Strong Opposition
In Chinese adults who lift weights for 12 weeks, people with a specific gene version (CC) tend to gain more bone in their arms than those with another version (CT). Men with this gene also tend to build thicker leg muscles, and women with it tend to get stronger at explosive movements after training.

VDR Gene Polymorphisms and Inter-Individual Variability in Response to Resistance Training.
Cohort Study
Human
2026 Jan 27The study found that people with the CT version of this gene, not the CC version, got more bone strength from training — which is the opposite of what the claim says. It did find CC helped men build leg muscle, but not in the way the claim described for bones or women.
Gold Standard Evidence Needed
