TRANSFER OF STRENGTH: WHAT CAN STRONGMAN LEARN FROM OTHER SPORTS? | Episode 3: Powerlifting as a Strongman Foundation, Maximal Strength Transfer and Limits of Specialization

Powerlifting as a foundation for Strongman: maximal-strength transfer and specialization limits

Powerlifting as a strength resource: foundation, not competitive equivalence

Powerlifting aims to express maximal strength in three standardized competition lifts: squat, bench press and deadlift. In strongman, the same broad muscular capacities may contribute to lifting, pushing and carrying objects, but results are also shaped by implement geometry, effort duration, grip, locomotion and event rules. The connection is strong enough to justify using powerlifting exercises in strongman preparation, but not simple enough to predict event performance from a three-lift total [1–3].

The International Powerlifting Federation specifies performance standards for depth and completion of the squat, paused bench pressing under commands, and controlled lockout of the deadlift. Such standards make competition more comparable, but they do not reproduce the entire challenge of an Atlas Stone, yoke carry or car deadlift. A conventional deadlift can closely resemble phases of a strongman movement while failing to reproduce its implement contact or event timing [1].

Understanding transfer requires separating strength potential from skillful application. A better squat may provide increased extensor capacity yet leave yoke pace limited by balance and gait. A larger deadlift may help lift an implement but cannot directly teach a grip transition around an irregular stone. Strength is a necessary resource for many events, not a sufficient condition for success in all of them.

Suchomel, Nimphius and Stone's 2016 review emphasized muscular strength as a major contributor to athletic force-time characteristics. It did not establish a formula translating additional squat kilograms into yoke meters. Transfer must be assessed through the target movement and its specific constraints. This episode therefore analyzes powerlifting's actual opportunities and limits rather than repeating the general framework already developed in the series introduction [2,3].

What the evidence establishes and what remains unknown

A 2019 systematic review investigated classic powerlifting performance, technique and training recommendations. Its authors identified a limited body of research and offered recommendations that require context. Their findings cannot demonstrate that the technique maximizing one powerlifting lift must also optimize a different strongman movement. Competitive rules define the valued performance in each sport. Low-bar squatting can maximize load in powerlifting without automatically reproducing frontal object carriage [4].

A longitudinal study published in 2022 examined records from 407 powerlifting meets involving 1,896 unique competitors and described changes in squat, bench and deadlift performance. The study offers valuable information on the long-term development of powerlifters, but did not test strongman transfer. Competitive records show what changed across years, without uniquely revealing the physiological mechanism or how many log repetitions would be gained [5].

A separate normative project analyzed hundreds of thousands of powerlifting entries, providing useful distributions of squat, bench and deadlift performance. Applying these norms directly to strongman is restricted by different participants, equipment, weight classes and outcomes. Exceptional relative strength does not guarantee superior performance when moving external loads over distance. Each prediction requires its own validated model [6].

The 2026 ACSM overview of 137 systematic reviews supports heavy resistance training as an effective means of developing maximal strength in healthy adults. Its findings justify including appropriately heavy work in strength development, but do not specify an ideal program for a highly trained strongman competing across numerous events. General training efficacy and transfer to a particular implement remain distinct questions [7].

On the strongman side, Hindle and colleagues documented a limited and heterogeneous biomechanics literature. We have strong general evidence that muscular strength matters and useful observations about selected events, but few controlled longitudinal studies directly comparing powerlifting programs with complete strongman outcomes. Powerlifting is consequently a rational training tool rather than a basis for invented event-specific transfer percentages [3].

Squat strength and the limits of axial loading transfer

The barbell squat develops force through coordinated hip and knee extension with torso stabilization. In powerlifting, bar placement, stance and depth are selected to achieve a valid maximal lift. In strongman, similar muscular resources may help the initial pickup of a yoke or a heavy stone, but the athlete must then walk or reposition the implement. Axial loading during squats does not automatically reproduce the coordination of walking with a yoke even when both impose large vertical forces.

A basic mechanical illustration helps explain the importance of position. A 200 kg mass contributes approximately 1,962 N of gravitational force. At a horizontal distance of 0.10 m from a chosen reference axis its idealized moment is 196 N·m; at 0.20 m the moment doubles to 392 N·m. These are not measured knee or lumbar moments: the complete system has multiple interacting forces. They simply demonstrate that equal nominal mass can impose different external demands when geometry changes.

Squat improvement may support more confident implement pickup or greater loading capacity. Yet yoke speed also depends on stride, object oscillation, traction and turning experience. An athlete may possess an exceptional squat and still waste time controlling a swinging frame. General strength improvement and event-specific coordination limitations can coexist.

There is no universal squat threshold after which strength development ceases to matter. However, very advanced athletes may improve more slowly while experiencing substantial fatigue from heavy training. In a strongman season, squatting needs to be scheduled around events stressing the same lower-limb and trunk systems. Potential transfer must be assessed alongside recovery cost.

A useful squat-to-yoke assessment separates initial frame pickup from the carry. Faster pickup without faster 20 m travel suggests phase-specific progress. Improvement in both is more suggestive of transfer, although practice and technical changes still need consideration. A single squat 1RM cannot stand in for every stage of the strongman task.

Deadlift and strongman: the most obvious resemblance can still mislead

Deadlifting appears to offer perhaps the clearest powerlifting connection to strongman. Many events require extending the hips and knees to raise a heavy object. But strongman deadlifts can involve thick bars, axles, car-lifting devices, different start heights, side handles and unusual mass distributions. Each variant changes center-of-mass placement, grip, trajectory and validation conditions. Standard barbell 1RM is a useful benchmark rather than a complete account of every derivative.

Powerlifting rules regulate grips, lockout and competition commands, while strongman may permit different equipment and scoring methods. An event can reward repetitions within a time limit rather than one maximum lift. An athlete with a high 1RM may have limited repeated-effort capacity over a taxing interval. Conversely, an athlete with a somewhat lower maximum may produce more repetitions through pacing and work tolerance. Neither capacity can be dismissed as false strength.

Winwood and colleagues compared the farmer's lift, deadlift and unloaded walking mechanics in a small group of experienced strongmen. They identified important differences in body position and ground reactions despite superficially related tasks. Their study was not longitudinal training research, but it provides direct evidence that picking up side handles is mechanically different from lifting a bar in front of the legs [8].

Side handles may permit different knee and torso geometry from a front bar. A thick axle changes the grip demands. A car-lifting device cannot be understood by simply citing vehicle mass because lever arms, pivot position and support points affect the actual forces experienced at the handles. Therefore stating that an athlete lifted a two-ton vehicle does not imply that two tons acted directly on the hands.

Deadlift transfer becomes more credible when the target is defined. Increased general strength may closely support a strongman barbell deadlift with similar equipment. For repeated car lifts or differently shaped implements, examine apparatus mechanics, grip, pacing, duration and recovery. A movement name alone cannot establish the magnitude of transfer.

Bench press and its actual contribution to strongman

The powerlifting bench press develops high force through pectoral, triceps and associated pushing musculature while the torso is supported on a bench and the lower limbs contribute to positional stability. Strongman overhead events operate under different mechanics: the athlete is usually standing, arms act at another orientation and the implement may have unconventional handles, diameters and mass distribution. Increased bench strength may create more capacity in elbow-extension muscles, but does not guarantee proportional improvement in strict press, push press or log lifting.

Transfer of a physical capacity differs from transfer of a movement pattern. The triceps extend the elbow in many exercises, but shoulder, scapula and trunk positions differ between horizontal and vertical pressing. During overhead lifting, stabilizing the object may become critical after elbow extension is nearly complete. An athlete with a large bench press may still be limited by overhead mobility, scapular control or balancing the implement above the support base. Excellent overhead athletes do not necessarily have equally exceptional relative bench results.

The classic powerlifting literature discusses grip and technical features that may maximize valid bench loads. Wider grips, legal arching and movement paths optimized for a barbell may increase competition performance. Such technical advantages cannot simply be imported to neutral-handled logs. Elbow position and implement trajectory have to be organized around different geometry [4].

Bench press can remain a useful auxiliary movement for muscular development and a controllable amount of pushing volume, potentially with less direct overhead exposure than repeated heavy log attempts. But the balance between bench and overhead work must reflect recovery and the actual competition limitation. If overhead stabilization is the bottleneck, additional bench may have limited immediate relevance; if elbow-extension force is inadequate, the rationale becomes stronger.

There is no validated equation by which a percentage of bench 1RM predicts log 1RM across athletes. Individual correlations do not establish causality. Transfer needs to be assessed against a defined strongman outcome while keeping specific practice and other training variables reasonably comparable.

Stones, sandbags and irregular-object pickup

Atlas Stones and heavy sandbags require hip and knee extension, secure contact and coordinated transitions that differ from standardized barbell deadlifts. A stone may be supported on the thighs before the arms are repositioned; its rounded or irregular geometry changes how far its center of mass lies from the torso. A sandbag can deform and redistribute its contents, introducing additional stabilization demands. Strength developed in squats and deadlifts may help pickup without automatically teaching the object interface.

Consider a 150 kg mass whose center of mass is 0.15 m anterior to a chosen reference axis. A simplified mgd calculation gives approximately 221 N·m. If the object shifts forward to 0.25 m, the value rises to about 368 N·m. These are not measured lumbar moments or muscle forces. They merely show how mechanical demand can change with geometry even when mass is unchanged.

Learning the actual movement affects the ability to express general strength. A competitor experienced at regripping and lap support may handle an implement that a technically untrained powerlifter cannot control, even if the latter has greater deadlift 1RM. This is a plausible scenario, not an experimentally demonstrated ranking of all athletes. Direct research is insufficient to calculate a universal average technical advantage for particular stone geometries.

Training should therefore combine appropriate general development with specific practice of contact, transition and stabilization. When an object is lost before the athlete reaches full extension, the reason should not automatically be attributed to posterior-chain weakness; friction, forearm positioning and implement shape need assessment. If contact is secure but the athlete cannot continue standing, general force capacity may deserve more attention.

Carrying stones or bags introduces a locomotor component absent from competitive deadlifting. Once the object is lifted, the athlete must control it through repeated steps, and fatigue can alter its position. General powerlifting strength addresses only part of that problem. Specific loaded locomotion and sustained-contact capacity must be evaluated separately [3].

Absolute versus relative strength

Powerlifting can be assessed through absolute loads, three-lift totals and body-mass-adjusted indicators. In strongman, body mass may have different consequences by event. Absolute strength can be crucial for maximal lifting, while in carries the athlete moves personal mass as well as external load. Additional body mass can therefore contribute to locomotor cost. In pulling tasks, the relationship among body mass, traction and downward force becomes more complex.

Assuming that a powerlifter deadlifting three times body mass will always outperform someone lifting 2.5 times body mass in a car deadlift is unjustified. Relative strength does not determine the actual force required at the handles of a lever system or repeated-effort capacity. Heavier athletes may possess greater absolute force but event outcome depends on mechanics. Powerlifting normative data are valuable for their own population rather than as a universal strongman qualification scale [6].

As a hypothetical comparison, Athlete A weighs 100 kg and lifts 250 kg, a ratio of 2.5. Athlete B weighs 150 kg and lifts 300 kg, a ratio of 2.0. Athlete A leads on the ratio, Athlete B on absolute weight. Their Farmer's Walk or truck-pull results cannot be deduced from those two values. Farmers require grip, handle geometry and speed; vehicle pulling requires traction, harness geometry and resistance.

Body mass also does not uniquely describe body composition. Athletes of similar weight may have different proportions and segment dimensions, affecting force production and implement support. Applied analysis can consider absolute and relative outputs while retaining the actual event result as its decisive measurement. Claiming any particular body composition necessarily wins without event-specific evidence would be speculation.

Muscle-mass development should be aligned with event requirements and any weight-class constraints. More total mass does not guarantee better performance, while aggressive short-term weight reduction can compromise recovery and force production. Decisions belong in a season-long performance and health framework rather than in pursuit of a single relative 1RM ratio.

One-repetition maximum versus time-limited repetition events

Powerlifters train to produce maximal force for one valid lift, while many strongman contests reward repetitions within a fixed period or sequences of events with limited recovery. Maximal strength can raise the ceiling of manageable load, but repeatability also depends on pacing, fatigue, technical efficiency and local recovery. No universal formula converts a powerlifting one-repetition maximum directly into log, axle or strongman deadlift repetitions.

Repetition calculators based on percentage of 1RM may offer rough estimates for comparable standardized barbell tasks, but are unreliable when transferred to unusual implements and fixed time limits. Athletes with equal maxima may have different pacing and local endurance. In strongman, rest between repetitions, regripping and contact rules can further change results. Generic 1RM equations are insufficient for such predictions.

Consider two hypothetical attempts in a 60-second event. One athlete performs five repetitions in twenty seconds, then spends twenty-five seconds recovering the position and manages one more. Another completes one repetition every eight seconds and finishes with seven. The first may be faster early on, but the second produces the better overall result. This does not establish a universal pace; it demonstrates why energy distribution and consistent repetition quality matter.

Maximal strength training can be complemented by methods developing repeated-force capacity without making every workout a failure test. Excessive repeated maximal attempts can compromise recovery and create considerable mechanical exposure. The 2026 ACSM overview does not support a universal requirement to train to momentary muscular failure for optimal outcomes. Programming should match the targeted quality and the athlete's history [7].

Transfer assessment should include both maximal strength and repetition-event results when relevant. When 1RM rises without more event repetitions, pacing or event-specific endurance may be worth investigating. When repetitions improve with a stable 1RM, technical and tolerance changes become plausible explanations. Neither scenario identifies the mechanism alone, but each guides more precise programming.

Yoke and Farmer's Walk: where barbell strength meets its limits

Yoke and Farmer's Walk are frequently described as manifestations of maximal strength, but success also demands producing and sustaining force while moving. A yoke transmits heavy loading through a superior frame that must be stabilized through alternating support steps. Farmer's Walk uses separate side-held implements, making grip a possible limitation before lower-body force capacity is exhausted. Better squatting or deadlifting may assist pickup without automatically improving walking speed or uninterrupted distance.

Hindle and colleagues' strongman review and specific Farmer's Walk research describe meaningful differences among loaded walking, initial lifting and barbell exercises. In an experimental comparison involving six experienced strongmen, Winwood and colleagues identified differences in posture and force characteristics between a farmer's lift and deadlift, along with gait differences between loaded and unloaded walking. The small sample limits numerical generalization, but the finding establishes that side-held loads change movement mechanics rather than merely adding mass [3,8].

A yoke frame can oscillate during gait, requiring corrections absent during a stationary squat. Excessive acceleration may increase sway and reduce average speed. Frame height, support points and width can affect the mechanical challenge. No universal squat percentage predicts 20 m time across all yoke implements.

In Farmer's Walk, handle geometry and grip surface matter. A powerlifter accustomed to a standardized bar or mixed grip may need practice supporting two separate moving weights. Competition rules regarding accessories can change the limiting requirement. A very high deadlift 1RM does not eliminate the need for grip preparation appropriate to the event.

Practical analysis should separate pickup, early acceleration, middle-course speed and turns. Faster pickup after a squat-focused phase without faster walking suggests possible partial transfer. Faster walking with unchanged 1RM suggests technical or locomotor adaptation. Programming should respond to the observed limitation rather than assuming that every phase requires the same resource.

Powerlifting technique: legitimate specialization and reduced transfer

Powerlifting rewards efficient technique under tightly defined rules. Athletes learn stance, grip, bar path and timing that maximize one valid lift. Some technical choices increase result by reducing required displacement or placing joints favorably relative to the barbell. Such specialization is a legitimate feature of the sport. Difficulty arises only when a technique advantage under standardized rules is interpreted as a universal capacity that must appear in every loaded movement.

A low-bar squat may permit greater load than a high-bar alternative for some athletes, but an anteriorly held stone creates different lever arms and torso demands. The difference between squat styles therefore does not establish which is best for irregular-object pickup. Powerlifting research informs competitive technique preferences rather than supplying universal strongman prescriptions [4].

In deadlifting, conventional and sumo styles differ in stance, segment geometry and bar displacement. A strongman event with side handles or a higher start may favor yet another arrangement. Without analysis of the actual target movement, neither style can be recommended as universally superior across all implements. The same caution applies to trunk angle, footwear and grip.

Specialization also affects time allocation. An experienced powerlifter may possess exceptional force capacity in three lifts but limited loaded-carry or throwing experience. More practice solely in those three lifts may bring smaller marginal benefits than a period of event familiarization. Conversely, a technically skilled strongman whose maximal strength is clearly limiting may benefit from a focused general-strength phase.

There is no contradiction between real strength and technical skill. Both matter, and outcomes depend on their interaction. A capable coach can retain productive elements of powerlifting preparation while discarding specialized details that do not serve the new task. Transfer means choosing useful capacities and principles, not copying every aspect of competition technique.

Strength reserve: why a larger maximum can make a fixed load easier

Increasing 1RM can reduce the relative intensity of a fixed external load within a comparable exercise. If an athlete initially lifts 200 kg, a 150 kg load represents 75% of 1RM. If maximum rises to 240 kg, the same mass represents 62.5%. Within that exercise, the lower relative intensity may permit lower perceived effort or more repetitions, other conditions being equal. The ratio is mathematically correct; it does not demonstrate a particular percentage improvement during a different strongman carry.

A greater force reserve can support initial implement pickup while the final task remains constrained by grip or stability. Imagine an athlete capable of lifting a sandbag but losing it after the first meters. More deadlift strength might reduce the relative cost of pickup without correcting contact loss. The physical resource improves without removing the decisive bottleneck.

Relative 1RM percentage should not be equated with metabolic demand. A load representing 60% of maximum in one movement can still be extremely fatiguing when held for long periods with repeated walking cycles. Repetition count, sustained contraction and mass position influence the task. An athlete can possess strength reserve while remaining limited by local fatigue or difficulty breathing under frontal load.

A useful assessment compares maximal-strength changes with standardized submaximal event performance. If both improve under consistent conditions, practical transfer becomes plausible. If only the barbell maximum changes, other constraints require investigation. If the event improves with unchanged maximum, technical efficiency or pacing may explain some gains. No invented universal transfer ratio is needed.

A larger maximum can expand the athlete's options without requiring frequent maximal attempts. Some strength work can be maintained while more recovery resources are allocated to priority events. The decision belongs to the athlete's level and competitive calendar, not constant record chasing in every barbell lift.

Fatigue and recovery: why gym maximums are not always available in competition

Powerlifters prepare for a small number of maximal attempts with structured rest and event order. Strongman contests involve numerous heavy tasks, often over one or more days, including timed repetitions and loaded locomotion. Heavy training adaptations are not expressed in isolation. Accumulated fatigue from pulls, carries and overhead lifts can reduce later-event performance even when the athlete's rested 1RM is excellent.

Multiple fatigue processes interact. Repeated contractions can reduce force and velocity, while grip and torso systems may have distinct endurance constraints. Losing a farmer's carry after heavy deadlifting does not mean maximal strength has permanently disappeared; performance may be transiently impaired. Training must account for actual competition sequencing and individual recovery.

A block with many heavy deadlift sets may provide a strong stimulus but temporarily compromise stones or yoke sessions. Accordingly, programming evaluates both theoretical benefit and weekly fatigue cost. Repeated maximal-effort volume without suitable recovery may reduce the quality of the practice that matters most. This observation supports fatigue monitoring rather than one universal weekly split.

For scientific comparison, a rested 1RM should not be treated as equivalent to an event performed after multiple previous challenges. To estimate exercise transfer, testing conditions should remain reasonably consistent. To anticipate competition, however, the ability to express capacities after other events also matters. Those questions require different tests.

Strategically, an athlete may accept a temporary reduction in gym performance in exchange for better event-specific preparation when overall contest results are the goal. In a multi-event sport, optimizing one maximum may properly be subordinate to developing a complete performance profile. This is not an argument against maximal strength, but against mistaking one test for the entire sport.

Programming maximal strength inside a strongman preparation cycle

Integrating powerlifting exercises into strongman does not require reproducing a powerlifter's entire season. During a preparation period far from competition, an athlete may devote more time to general muscular development and strength under standardized conditions. As events approach, emphasis can shift toward actual implements and rules while enough strength work remains to preserve important resources. This is a defensible programming possibility, not proof that every strongman needs an identical periodization model.

The 2026 ACSM synthesis supports heavier loading for developing strength while acknowledging flexibility in multiple training variables. Its populations were heterogeneous, so it does not determine a universally safe or optimal workload for elite strongmen. Currier and colleagues' 2023 network meta-analysis likewise helps compare prescriptions for strength and hypertrophy but does not predict exact strongman event outcomes from each method [7,9].

A rational program separates maximal capacity development from event-specific holding and movement ability. Squats, deadlifts and presses may remain important, but carries, throws and awkward implements require their own practice. A contest emphasizing very heavy maximum lifts may justify more maximal-strength training, whereas speed and carriage events may require greater loaded locomotion and skill emphasis. No magic ratio of training minutes applies across calendars.

Overlapping fatigue is a practical concern. Many heavy deadlift sets can degrade a subsequent stone session if recovery is insufficient. Heavy yoke work may make a later squat session difficult. The solution is not necessarily removing either exercise, but regulating their ordering and volume so priority sessions retain reasonable movement quality. Fatigue observations and reproducible performance matter more than copying an arbitrary number of sets.

Near competition the objective is often to express previously developed capacities rather than set new records in every assistance lift. Reduced fatigue may make existing strength more available. No single meta-analysis establishes one universal taper duration for strongman. The athlete's history, event demands and competition length matter. Maximal strength should remain valuable without consuming all recovery resources.

Measuring transfer without inventing coefficients

Assessment begins with a specific strongman task, such as picking up and carrying a yoke for 20 m. Verify mass, frame geometry, support height, ground surface, turns and timing. Record pickup and walking separately. After a squat-oriented intervention, repeat the test under comparable recovery conditions. Improvement confined to pickup is a phase-specific observation rather than proof that every component of carriage improved.

Suppose total time falls from 21 to 19 seconds, a two-second reduction or approximately 9.5% of baseline time. If squat 1RM rose by 8%, dividing the percentages does not reveal a transfer coefficient of 119%. The metrics describe different phenomena, have different errors and may be related nonlinearly. Carry practice or altered pacing could also produce some of the improvement. A simple ratio cannot establish causality.

Stronger evidence could compare athletes receiving the same event-specific practice but different auxiliary interventions, one including focused powerlifting and another an alternative of comparable training cost. Outcomes would be prespecified and measured consistently before and after. Elite strongman research is difficult because samples are small and implements vary. Those limitations require transparent protocols and uncertainty estimates rather than confident universal claims.

Training logs can still inform practice without randomization. Preserve squat, bench and deadlift results alongside implement conditions, segment speeds, valid repetitions and perceived fatigue. If a large deadlift improvement is not followed by better car-lifting performance, examine apparatus geometry and repetition capacity before declaring the deadlift irrelevant. If both improve, the relationship is encouraging but may still involve learning.

Repeatable submaximal assessments may be more useful than weekly maximal records. Health, safety and recovery deserve priority. Repeated extreme attempts can create fatigue without clarifying the mechanism. Performance should be measured in meaningful conditions, but not through unnecessary mechanical exposure.

Conclusion: powerlifting raises the ceiling, strongman requires its application

Powerlifting provides a coherent foundation for developing maximal force through heavy progressive work with standardized exercises. Squats can improve capacities relevant to supporting and picking up loads; deadlifts can have direct application to certain lifting events; bench pressing can develop resources used in pushing. None automatically solves gripping an irregular object, controlling yoke oscillation, moving under load or stabilizing a giant dumbbell overhead.

Powerlifting specialization is both an advantage and a limitation. The advantage is the ability to express high force in well-practiced lifts. The limitation is that results partly depend on the geometry and rules of those lifts. Different implements require new force organization and motor solutions. This does not diminish barbell training; it defines its place within multi-objective preparation.

Scientific evidence supports strength development through heavy training and shows that strongman implements can impose distinct mechanics from conventional exercises. Direct evidence quantifying the transfer of specific powerlifting interventions to every strongman event remains limited. Universal numerical predictions would replace research with guesswork. Credible advice identifies the target task, the observed constraint, training cost and a means of measuring improvement [2–9].

The useful question is not whether a powerlifter can become a strongman or whether maximal force matters. It is how much of the capacity developed through squat, bench and deadlift becomes expressible with a particular implement, technique and competition context. The answer varies by athlete and event. When mechanical rationale and reproducible improvement align, transfer can be considered useful. When the expected outcome fails to appear, programming should change without dismissing the value of general strength.

Across this series, powerlifting and Olympic lifting are not competing ideologies. One can be especially helpful for building a large maximal-force reserve; the other offers tools for force-production velocity and explosive coordination. Strongman can integrate them selectively with implement-specific practice and transparent performance assessment. What matters is not the prestige of the borrowed exercise, but what it demonstrably changes in competition.

Joint angles and lever arms: strength is not a uniform reserve

Maximal exercise performance depends on the positions through which the athlete must move. In squatting, gravity and the barbell create external moments that are balanced through muscular actions and ground reaction forces. Hip, knee and ankle angles change throughout the descent and ascent. In deadlifting, bar position relative to the legs and torso changes the balance of demands among body segments. No single value called leg strength describes every joint angle and every lifting task.

The strongman problem is more complex because the object does not necessarily have the same mass distribution or path. A sandbag's center of mass can shift slightly as its contents settle. A log's handles alter arm geometry. A car deadlift apparatus modifies actual handle resistance through levers and supports. Consequently, gains at one position in a barbell lift may contribute without guaranteeing that every critical phase of a different object becomes easier.

A simple model shows how lever arms matter. For an external gravitational force of approximately 2,000 N, a perpendicular distance of 0.10 m corresponds to a 200 N·m moment; at 0.25 m it corresponds to 500 N·m about the chosen reference axis. These figures are not measurements of muscle force or intervertebral disc compression. The complete human-object system has many interacting forces and contacts, and clinical internal-force estimation would require a substantially more detailed model. The illustration shows only why unchanged mass can create different mechanical requirements as position changes.

Partial-range exercises, rack pulls and other modified movements may emphasize particular positions, but they do not universally replace broader-range strength training. Nor should they be selected solely because they permit greater nominal loading. The 2026 ACSM synthesis reported advantages of full range of motion for some strength outcomes in the populations studied, without establishing that every partial-range application is useless [7].

For strongman, the question is where the actual bottleneck appears. If the implement rises rapidly from the floor but cannot clear a platform edge, analyze the mechanics of that later phase. If a stone cannot be raised from a low pickup position, extra strength only near deadlift lockout may have limited immediate value. Training a relevant range can be plausible, but the improvement has to be assessed on the target implement, not solely on bar height in the gym.

Grip geometry can change together with joint angles. An athlete may have sufficient extension force but be unable to maintain contact through the transition. An analysis focusing exclusively on the knee or hip could miss the cause. Biomechanics should therefore be used to diagnose the integrated athlete-implement-ground system rather than to justify a single favored exercise.

The distinction also cautions against interpreting absolute kilograms without setup information. A rack pull performed above the knee and a full deadlift from the floor can have very different moment profiles despite sharing a name. Neither can be translated directly into a given strongman object merely by comparing maximum loads. Researchers should describe start height, implement dimensions and movement path before attempting such comparisons.

A defensible intervention would test whether the chosen exercise changes the event phase that was identified as limiting. Improvement in the auxiliary movement alone shows local adaptation. Improvement in the specified event phase is stronger evidence for practical transfer, though familiarization and other training still need consideration. The actual event remains the final test of whether the new capacity is usable.

Force availability over time: from a maximal attempt to implement acceleration

A powerlifting maximum is important, but the time allowed for force application varies among tasks. A maximal deadlift can proceed slowly because success depends on overcoming extremely high resistance along a specified path. A heavy carry or vehicle push may demand initial acceleration followed by sustained movement and repeated forces during each step. Increasing 1RM can raise the force ceiling without automatically improving how quickly force becomes available during the crucial part of a faster event.

Reviews of muscular strength and athletic performance indicate that stronger athletes often have favorable force-time characteristics, but do not prove that a particular 1RM increase guarantees an equivalent gain in sprint or yoke performance. Coordination and task specificity influence actual transfer. For someone capable of supporting a load but slow to accelerate it, exclusive emphasis on maximal attempts may become insufficient even while maintaining maximal strength remains valuable [2,10].

Mechanical impulse is relevant because a net force acting through time changes momentum. In a simplified example, a constant-mass 300 kg object receiving a net impulse of 150 N·s changes velocity by approximately 0.5 m/s. This does not determine the athlete's actual pull force in a car deadlift or truck event because the resisting forces and contact interactions have not been specified. It illustrates why mass, net force and time belong in the same mechanical analysis.

Training can combine appropriately heavy lifts with faster actions without assuming that every repetition must be maximal or that uncontrolled acceleration is desirable. The ACSM synthesis identified loading and movement characteristics associated with power development that differ from those tending to maximize conventional 1RM gains. These findings concern broad healthy-adult populations and do not dictate one strongman prescription, but they support distinguishing the qualities being trained [7].

Individual failure in a speed-based event can arise from insufficient maximal strength, inadequate force production within the useful interval or inefficient movement strategy. A single video may not identify which explanation is correct. Standardized submaximal tests, phase-by-phase observation and performance history are valuable. If squat improves while yoke acceleration remains unchanged, a technical or locomotor intervention may deserve investigation before further maximal-load increases.

A practical distinction is between the initial attempt to move an object and maintaining motion once it is already moving. Static friction or other resistance conditions may differ from dynamic conditions. A better deadlift can help at initiation without necessarily producing optimal cadence later. A coach who measures only the final completion time may overlook such phase-specific transfer or its absence.

The ability to apply force in the appropriate direction also matters. A strong athlete can waste effort when a harness, handle or body position directs force unfavorably. Mechanical coaching can improve how available strength reaches the object without changing the underlying 1RM. This is a useful reminder that force capacity and efficient transmission are different outcomes.

Ultimately, powerlifting offers a force resource from which strongman performance can be developed. Expressing that resource within the target implement's time window, direction and stability demands is a separate problem. This distinction helps justify combining training methods from different sports while refusing to treat any one method as sufficient for every event.

Equipment and rules: the instrument defines what strength is measured

Rules define a valid competitive result. In powerlifting, barbell characteristics, plates, squat depth, commands and lift completion are standardized to allow comparison. In strongman, an organizer may use a lever apparatus, oddly shaped object, route or scoring format that substantially changes the task. A conventional deadlift maximum cannot be compared with a car deadlift while ignoring the difference between nominal vehicle weight and the actual force experienced at the handles. Those quantities are not necessarily equal.

In an idealized lever, moment depends on force and perpendicular distance from the pivot. If a load acts at a 0.50 m moment arm and the athlete applies force through a handle at 1.00 m, a simple static balance suggests handle force of about half the relevant load force, ignoring device mass, friction and other interactions. In real equipment, lever arms and resistance can vary with angle and displacement. The illustration shows why lifting a car cannot automatically be reported as deadlifting its full mass.

Some strongman events use thicker bars, unconventional handles or equipment rules different from powerlifting. A grip supporting an enormous standard-bar maximum may not be available in the target event. When grip contact fails, additional hip-extension capacity cannot be expressed through that object. Equipment is therefore not an incidental detail outside performance; it defines part of the mechanical task.

Useful documentation includes verified mass, starting position, handle height, bar or apparatus type, permitted accessories and judging requirements. Without these details, comparisons between events or between gym and field results may become misleading. A large number on an official results sheet can be valid within its own contest without representing the same mechanical exposure as an identical number obtained elsewhere.

The details can guide exercise selection. When a strongman deadlift closely resembles a conventional barbell deadlift, focused general strength work may transfer more directly. When an unusual lever or object interface dominates, equipment familiarization and analysis of actual resistance deserve greater priority. This does not deny strength developed through powerlifting; it specifies how that strength can reach the target task.

The principle extends to apparently simple carries. Farmer's Walk handle diameter and the load's center of mass can affect holding difficulty without changing nominal mass. Yoke support height influences body and implement geometry. Results should consequently be interpreted alongside implement specifications, and powerlifting analogies should be used carefully.

The same concern applies to the use of straps or other permitted assistance. An event that permits external grip support has different limits from one that demands unaided hand contact. A deadlift test using one equipment configuration should not be assumed to predict another configuration with a different limiting mechanism. Comparing athletes fairly means comparing the same rules and equipment, not merely the same displayed kilograms.

From a research perspective, standardizing apparatus geometry reduces unwanted variance and makes longitudinal conclusions more credible. From a coaching perspective, understanding differences prevents misdiagnosis. An athlete may not need more general pulling strength if the main difficulty is an unfamiliar lever path. Mechanical diagnosis can save substantial training effort while preserving the benefits of strong barbell foundations.

Breathing and trunk stabilization across standardized and awkward loads

Very heavy lifts require athletes to control the torso while external forces create moments about body segments. Bracing strategies, including changes in intra-abdominal pressure, can contribute to managing position. Yet the core is not a single muscle or a fixed force quantity transferable unchanged between squats and stone carries. A bar supported across the back, a stone pressed into the abdomen and two masses suspended from the hands distribute their demands differently.

A powerlifting maximum is performed within a limited movement period, and athletes may adopt breathing strategies suited to that effort. During a prolonged strongman carry, sustaining the same breath-holding pattern can become impractical and risky. Frontal pressure from an object can alter breathing comfort, while walking requires repeated support cycles. Recommending one breathing maneuver for every event because it was effective during a single deadlift is unjustified.

Functional trunk stabilization should be understood as controlling movements that threaten the implement while allowing movement necessary for the task. During a heavy squat, the athlete follows a relatively constrained descent-and-ascent path. During yoke walking, pelvis and torso continually adjust to alternating steps. Effective stability in the two conditions may therefore require different motor strategies even though several muscle groups are shared.

There are insufficient direct studies to assign a precise percentage transfer of bracing capability from squatting to a Húsafell carry. Anterior-load-carriage and Farmer's Walk research provide plausible mechanisms, but their participants, loads and interfaces differ from many competitive events. Individual observation can assess implement sway, regripping and speed deterioration without pretending to measure every internal muscle force.

A coach can differentiate lack of general trunk capacity from poor implement positioning only by observing the full system. An object gradually moving away from the body increases external moments and may make the athlete appear less stable, even if intrinsic muscular capacity has not changed. Improving contact or handle position may reduce demand and permit better use of existing strength. More barbell load is not always the immediate answer.

Respiratory behavior also matters for monitoring fatigue. If an athlete begins a carry with controlled breathing but later loses rhythm and posture, performance degradation may reflect several interacting constraints rather than one weak muscle. Timing and video can document when changes occur, although internal physiological explanation requires more elaborate methods. Interpreting a symptom from one video frame is not sufficient.

For safety, unusual breathing difficulty, dizziness or persistent symptoms should prompt stopping and appropriate evaluation rather than being treated as proof of effective bracing. A technique tolerable for one maximal repetition may be unsuitable for prolonged or repeated efforts. Training should allow controlled breathing and safe implement release under conditions consistent with the athlete and rules.

Barbell exercises can build general trunk-related resources while implement training develops task-specific contact and movement control. These directions complement one another, but their outcomes should be evaluated separately. An athlete may squat more than before and still need substantial experience to carry a large stone securely against the chest.

Importantly, different tasks also create different opportunities for recovery during an attempt. A powerlifter can generally set down the bar after completing the repetition; an athlete midway through a long carry may be unable to rest without terminating the event. Breathing and bracing strategies must therefore fit the time structure and the rules of the task, not simply its peak load.

The broader lesson is that trunk strength is only meaningful when its operational definition is stated. A longer isometric hold, a heavier squat and a steadier yoke all provide information, but measure different combinations of physical capacity and skill. Treating them as the same outcome obscures both the opportunities and limits of transfer.

Strength across years, not weeks: what powerlifting records can teach

Maximal strength performance develops over long periods through interacting muscular adaptations, technique, recovery and competition experience. Latella and colleagues' longitudinal study examined 407 meets and approximately 1,900 unique athletes, describing changes in squat, bench and deadlift results over time. Outcomes differed between lifts, and athletes already at very high strength levels could improve more slowly than less advanced competitors. This helps set realistic expectations, but it is not an individualized forecast for every strongman [5].

Competition archives contain an important selection issue. Athletes who continue participating and therefore appear in repeated records are not necessarily representative of those who retire or compete infrequently. Official results also depend on attempted loads, meet strategy, body mass and preparation. Long-term improvement cannot be attributed to one specific training method without intervention data. Archival work describes performance development rather than causally establishing transfer.

For an advanced strongman, pursuing new records in all three powerlifting lifts may become increasingly expensive in time and recovery as marginal gains slow. This does not imply abandoning maximal strength. It creates a reason to allocate some resources toward implement skills where the athlete may still improve substantially. A competitor unfamiliar with a carry may improve rapidly during early practice, whereas another five kilograms on a highly developed squat could require lengthy preparation.

Comparing athletes across sex or body-mass categories requires care. Normative data derived from hundreds of thousands of powerlifting entries provide distributions within that sport rather than a shared ranking of strongman carrying ability. Identical body-mass-to-1RM ratios do not imply identical loaded-locomotion performance. Body proportions, implement geometry and specific experience can influence results.

Long-term preparation should distinguish general capacity development from seasonal specialization. Athletes competing frequently in strongman may need periods emphasizing maintenance of maximal strength while prioritizing recovery and event practice. Beginners may receive substantial value from building a barbell strength base. The deciding considerations are training level, prior exposure and observed competition limitations rather than chronological age alone.

This perspective also improves interpretation of an individual result. A brief deadlift plateau does not mean further strength development is impossible. A single personal record does not prove a permanent change either. Repeated measurements under comparable conditions and adequate recovery offer stronger information than reactions to isolated performances.

The same reasoning applies to the relation between strength and technique. An advanced powerlifter may be close to personal technical limits in the three competition lifts but comparatively inexperienced with strongman objects. That athlete's next meaningful performance gain could come from learning rather than from muscle development. Another strongman might possess superb implement handling and little remaining technical opportunity while still having clear room for greater general strength.

Consequently, broad norms and averages can help frame expectations without dictating the next exercise. Individual monitoring should identify where the athlete is now, what competition demands and which constraint appears modifiable at an acceptable cost. That is the useful connection between long-term powerlifting evidence and strongman programming.

Interpreting failed attempts: force, technique or strategy?

A missed attempt is an external outcome, not a complete diagnosis. When an athlete cannot lift an implement, the cause may be inadequate force in the critical position, but also grip loss, an unfavorable path, accumulated fatigue or timing error. Strongman events can involve several mechanisms simultaneously. Analysis should identify where movement stops rather than reflexively prescribing more deadlifts for every failure or dismissing every failure as a technique issue.

A lateral video can reveal approximate trunk orientation and object movement, while a frontal view can expose asymmetry and balance loss. Without calibration, however, angles and velocities remain approximate, and internal muscle forces cannot be identified directly. If an athlete lifts a stone to the thighs but cannot bring it to the chest, contact geometry, movement access or force capacity may be responsible. Video generates testable hypotheses rather than precise physiological diagnoses.

Consider a hypothetical athlete whose deadlift improves from 260 to 275 kg over eight weeks while repetitions on a car deadlift remain unchanged. The 15 kg change demonstrates progress in the barbell test if conditions are comparable. It does not establish improvement in the vehicle event. The lever apparatus may produce another resistance profile, or pacing and recovery may be limiting. Two numbers do not identify the mechanism.

In a different scenario, 1RM stays at 260 kg while the athlete achieves two additional repetitions on the same car apparatus. This may reflect technical learning, breathing organization, pacing or better repeated-effort tolerance. It would be incorrect to conclude that strength does not matter: completing each repetition still requires adequate force. What improved may be the capacity to express the existing force reserve over time.

A rational decision requires repeated observation. If failure occurs during initial pickup while rested, start position and force production deserve attention. If performance collapses near the end of the time limit, duration and pacing become more relevant. If the athlete loses position only during turns, locomotion and stability may dominate. These observations suggest different training options, and several bottlenecks may coexist.

It is especially important not to confuse perceived effort with the cause of failure. An athlete may report that a movement felt impossibly heavy when an unfavorable grip actually increased the required muscular effort. Another may feel confident in the grip but fail because the available external moment cannot be overcome. Subjective experience is valuable context, not a substitute for mechanical analysis.

Training interventions can also create misleading short-term observations. After a demanding maximal-strength phase, a strongman may be fatigued and perform worse on event day even while general capacity has improved. Repeating the event test after appropriate recovery can help distinguish transient fatigue from persistent failure to transfer. Conversely, unusually good performance after a rest period may represent readiness rather than a permanent change in strength.

When a new implement is introduced, learning effects are likely. The first few exposures should not be taken as stable baseline measures without familiarization. If athletes improve simply through becoming comfortable with the object, claiming that an auxiliary powerlifting exercise caused the change overstates the evidence. Event practice must be documented as part of the intervention context.

A complete evaluation may include the barbell strength change, event-specific outcome, movement-phase timing and implement conditions. When these measures tell different stories, the discrepancy is informative. It may reveal where the transfer hypothesis was too broad or where the actual bottleneck lies.

Powerlifting-to-strongman transfer is therefore a differentiated diagnostic problem. Squats, bench presses and deadlifts develop important capacities, but their greatest practical value arises when directed toward observed demands and evaluated on competition implements. Without that connection, gym results and competition results may evolve differently even though neither measurement is invalid.

Load tolerance and risk: preventing the foundation from becoming a fatigue burden

Maximal strength develops through progressive exposure to substantial resistance, but strongman programs already contain considerable loading of the torso, legs and upper limbs. Adding large volumes of heavy squat, bench and deadlift work to yoke, stones, carries and overhead sessions can increase fatigue without proportionate competitive benefit. Training needs to account for total work and overlapping tissue demands rather than looking only at percentage of one-repetition maximum in the primary barbell exercise.

The strongman injury literature documents musculoskeletal problems among athletes, but does not provide universal individual safe-loading thresholds. Familiarity from powerlifting does not make an exercise risk-free, and the unusual appearance of strongman implements does not mean every such activity is inherently unsafe. Risk depends on exposure, progression, technical control, medical history and training environment. There is no universally safe count of heavy repetitions per week.

Unusual persistent pain, functional loss, neurological symptoms or other significant physiological problems deserve stopping and appropriate assessment rather than being treated as tests of mental toughness. Position loss during a maximal lift can alter external loading substantially; during awkward-object work, dropping the implement can create additional impact hazards. Training space, qualified supervision and controlled release procedures therefore matter.

A practical criterion is the relationship between stimulus and recovery. If deadlift results improve while yoke-session quality consistently deteriorates from fatigue, the program needs adjustment. Options may include reducing volume, changing session order or maintaining strength with a smaller training dose. No single configuration suits every athlete. The objective is better overall contest performance rather than the largest gym number in isolation.

Simple monitoring can include load, repetitions, perceived difficulty, session duration, sleep quality and performance in specific events. These observations do not replace medical care and should not be marketed as precise injury predictors. They can help identify trends and inform scheduling. When a powerlifting intervention produces strength progress but persistent declines in event practice, its useful transfer must be reconsidered alongside the recovery cost.

Preparing for strongman through powerlifting does not mean taking every exercise to failure every week. It means using maximal strength as a capacity that can be built and maintained rationally. Clear objectives, appropriate rest and realistic testing offer greater practical value than undifferentiated accumulation of maximal efforts.

Exercise selection should also consider the difficulty of safely abandoning the load. A barbell in a designated rack or on an appropriate platform creates different escape options from an awkward object held against the chest or a heavy frame moving at speed. Exposure progression should reflect these differences. A general-strength exercise that is productive in one setting may need modification when equipment, space or supervision changes.

Recovery cannot be inferred from one universal number of hours. Training age, recent volume, nutritional status, sleep and the specific tissues stressed all contribute to readiness. Monitoring useful event performance helps determine whether general strength work is supporting or competing with competition preparation. The athlete's response is more informative than assuming everyone should tolerate the same weekly program.

Importantly, risk management is not the enemy of high performance. The capacity to train consistently over months can itself become a competitive advantage. A program that occasionally produces an exceptional gym maximum but repeatedly disrupts specific practice may deliver less long-term value than one balancing general strength and event work more consistently.

Experimental design and a critical conclusion about strength transfer

A modern study of powerlifting-to-strongman transfer should begin with a precisely defined task rather than the vague category functional strength. Researchers might choose a standardized carry or a particular strongman deadlift apparatus, documenting verified mass, contact geometry, start height and validation rules. Athletes would receive comparable familiarization and be assigned auxiliary interventions for a sufficient period. One group might emphasize maximal barbell strength while another follows a different method with reasonably similar workload and recovery costs.

Assessment should include the actual competitive outcome together with intermediate variables such as barbell 1RM, pickup time, segment velocity and regripping frequency. If a group achieves greater squat gains and also shows reliable improvement on the target event, evidence for useful transfer becomes stronger. If only the barbell test improves, local adaptation has been demonstrated, but transfer to the specific event has not. Interpretation needs uncertainty estimates and individual-response information.

Recruiting large elite samples is difficult, while repeated maximal strongman attempts may be unsafe or impractical. Manageable standardized tasks can be combined with actual contest records. The essential requirements are transparent methods and outcomes that are not redefined after seeing the data. A study showing strength improvement without target-event benefit provides important information rather than a failure to deliver positive results.

A more modest coaching evaluation might obtain several baseline observations, introduce a defined block and retest after comparable recovery. This is weaker than a controlled trial for causal inference but far more informative than assuming a squat record must automatically become a yoke record. The training log becomes a learning instrument when it includes hypotheses that were not confirmed.

The central conclusion is that powerlifting develops valuable force capacity while its technical specialization restricts automatic transfer. Strongman requires expression of strength through different implements, time limits, contacts and movement paths. A large force reserve can help pickup and support, but successful performance depends on the whole system of demands. Intelligent integration retains maximal strength development while adding the capacity to use it.

This relationship captures the complementarity between disciplines. Powerlifting may build the strength ceiling, while strongman tests how that ceiling can be applied under varied constraints. A strong program does not choose strength instead of skill. It measures both and invests in the currently important limitation while protecting long-term recovery and health.

In research reporting, a distinction should remain between stronger evidence for general resistance-training adaptation and weaker evidence about direct transfer to uncommon elite implements. A systematic review of healthy-adult training can provide useful background, but a clinical or recreational sample is not identical to competitors handling loads at the extremes of human performance. Expressing this limitation is necessary even when the proposed mechanism is sensible.

Likewise, an association between high deadlift strength and strongman success would not prove the isolated causal effect of increasing deadlift 1RM. More successful athletes may also be more experienced, heavier or better coached. Longitudinal comparisons, stable implement conditions and explicit documentation of specific practice are needed to reduce such alternative explanations.

Coaches can still act under uncertainty. Training decisions rarely wait for perfect experiments, and practical expertise can identify plausible priorities. What matters is presenting them as hypotheses, monitoring outcomes and changing course when the evidence from the athlete contradicts expectations. That approach respects scientific reasoning without denying the constraints of real training.

The final standard is concrete: a stronger athlete must become a more capable competitor in the event that matters. Sometimes the barbell maximum rises and event performance follows; sometimes the athlete needs more coordination, grip or sustained effort. Neither result is paradoxical. Powerlifting provides an important foundation, while strongman determines whether that foundation is being used effectively.

Performance transparency: what should accompany a record

A powerlifting record is interpretable only alongside the conditions under which it was achieved: competition rules, equipment, validated loading and performed movement. Comparable principles apply in strongman, where implement geometry, pickup height, course distance and scoring criteria must be documented. A result can be impressive and legitimate without being mechanically equivalent to another result from a differently equipped contest. Acknowledging this limitation does not diminish either athlete's accomplishment.

Research on cross-sport transfer would benefit from technical specifications for implements and simple, repeatable performance protocols. Without these, correlations between barbell one-repetition maximum and strongman results can be distorted by equipment and familiarization differences. Coaches can still collect valuable individual data by testing under consistent conditions and documenting any changes.

Data comparisons should distinguish absolute loads from task difficulty. Two athletes moving nominally equal kilograms may experience different grip, posture or resistance demands. Similarly, a lever-based deadlift apparatus cannot be described fully through the vehicle's mass alone. Interpreting results requires information about the mechanical interface that connects athlete to load.

The same standard applies to apparent improvements over time. When a competition changes its course length or lifting apparatus, the new result cannot automatically be compared with the old as a direct measure of physiological progress. A better time might reflect an easier course or more effective strategy, while a worse time might reflect more demanding equipment. Progress should be assessed with those conditions visible.

Transparency also matters when an athlete switches sporting emphasis. An experienced powerlifter can bring excellent maximal strength to strongman while learning novel techniques. Early gains may be dominated by familiarization, not rapid changes in muscle capacity. Recording both barbell results and event-specific performance allows a more useful picture of the process than reporting a combined number without context.

The practical conclusion is straightforward. Strength built through powerlifting is a valuable resource, but its transfer must be established on the actual strongman task. Objective, repeatable measurements can identify when the resource becomes useful and when another constraint still limits performance. Such an approach respects the strengths of both disciplines without claiming that their competitions measure identical abilities.

Interpreting transfer also requires caution about time. Results measured during temporary fatigue, after a particularly favorable recovery period or on unfamiliar equipment may differ substantially from the athlete's stable ability. A stronger deadlift and a faster carry observed in the same period do not demonstrate that the former caused the entire improvement in the latter. Both might reflect improved training quality, better recovery or increased event-specific practice. Repeated comparable tests and transparent training records provide a stronger basis for interpretation than a convenient pair of personal records. Coaches can act on plausible evidence while distinguishing observation from causal certainty. The value of barbell strength should be recognized without assigning it an invented percentage of every strongman result.

A final methodological safeguard is to preserve implement mass, geometry, course and judging requirements whenever performance is compared over time. If any of these variables changes, report the change explicitly. Without that information, apparent improvement may reflect a different task rather than a stronger or more skillful athlete. Transparent reporting makes both favorable and unfavorable findings more useful for future programming decisions.
