Building a Champion - Episode 1: Genetics and Potential

BUILDING A CHAMPION - EPISODE 1: GENETICS AND POTENTIAL

A champion does not begin with a training program. It begins with an organism that has certain characteristics, some inherited, some built, and many shaped by continuous interaction with the environment. In Strongman, performance is multidimensional: maximal strength, power, muscle mass, anthropometry, muscle architecture, coordination, technique and training tolerance all meet on the same competition floor. Genetics can influence these components, but it does not lock them into a predetermined final number.

1. GENETIC POTENTIAL AND HERITABILITY
There is no single strength gene and no DNA value that tells us how much an individual will lift. Performance is a complex phenotype produced by interactions among many genetic variants, development, environment, nutrition, sleep, training and experience. Heritability is frequently misunderstood: a population estimate does not mean the same percentage of an individual's performance is genetic. Twin studies support a genetic contribution to strength and training response, but they do not produce an individual formula.

2. BODY STRUCTURE AND MUSCLE ARCHITECTURE
Strongman favors different biological combinations depending on the event. Body mass can help absolute strength, but mass is not equivalent to performance. Contractile tissue, mass distribution, limb lengths, joint dimensions, trunk length and force-transmission mechanics all matter. Physiological cross-sectional area, fascicle length and pennation angle influence the force-velocity relationship. The same anthropometry can help deadlift and be less favorable in overhead, Yoke or a medley.

3. STRENGTH, HYPERTROPHY AND TRAINING RESPONSE
Twin studies show individual variability in strength and adaptation. A 2024 genomic study assessed 440 previously inactive adults after 12 weeks of exercise and investigated genetic contributions to individual differences in muscle hypertrophy. The findings support a genetic component, but they do not provide a formula for predicting future muscle gain. One athlete may gain little measurable muscle and substantial strength through neural and technical adaptation; another may hypertrophy well but transfer less efficiently to an event. Potential should therefore be judged longitudinally through progression, volume tolerance, response to intensity, technique and transfer.

4. ACTN3, ACE AND THE CHAMPION-GENE PROBLEM
ACTN3 is the best-known gene in discussions of strength and power. The R577X variant affects alpha-actinin-3 expression in fast-twitch muscle fibers. A 2024 meta-analysis involving more than 14,500 participants found the R allele and RR genotype more common in power athletes than controls. A 2026 meta-analysis found associations between ACTN3 and selected measures of 1RM, maximal voluntary strength and jumping performance. These findings are scientifically relevant, but a population association is not an individual prediction. ACE is another example, with evidence too inconsistent to dictate programming. Modern reviews identify hundreds of markers associated with athlete status, strength, power or endurance, yet elite performance remains too complex to predict with a simple genetic test.

5. IDENTIFYING POTENTIAL
The most useful practical tool is longitudinal tracking. A very strong junior is not automatically a future champion. We need to see how quickly the athlete learns, responds to volume, builds muscle, recovers and transfers general strength into specific performance. Technical plasticity matters. A high-potential athlete learns quickly, accepts feedback, modifies technique and reproduces movement under fatigue. In Strongman, transfer is critical. An athlete may become very strong in the squat without becoming proportionally better at Yoke, while another may show a modest gym PR and a major improvement on Stones.

6. GENES AND ENVIRONMENT
Genes and environment build performance together. A favorable biological profile can remain unused without coaching, nutrition, sleep, equipment and years of work. An apparently ordinary profile can produce exceptional performance in the right environment. Early selection can confuse lack of experience with lack of potential. When we look at an adult champion, we see the final product of interaction between predisposition and experience, not DNA in isolation.

7. USING GENETIC INFORMATION
The scientifically cautious position is to treat genetics as context, not verdict. Genotype can generate a hypothesis; repeated phenotype can support or reject it. If an athlete progresses extremely well on moderate volume, training data should have priority over a commercial algorithm. If frequent technical exposure is needed, direct observation should lead the decision. Genetics should be neither an excuse nor a promise.

CONCLUSION
Do not search for the champion gene. Search for the combination of biological characteristics, adaptability, training response, technical skill, competitive psychology and environment. Potential is not simply what you have at the beginning. Potential is what remains possible after you have observed how the organism responds to intelligent, sufficient and repeated work. DNA can tell you something about the material. Only years of training show what can actually be built from it.
