The Claim
Among trained individuals, a higher proportion experience muscle hypertrophy exceeding the typical measurement error when following an individualized resistance training volume protocol compared to a standardized one, with an estimated difference of 50% (95% CI: 21.2–78.7%).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who already train regularly are more likely to see real muscle growth when their workout plan is customized for them, rather than using a one-size-fits-all routine — and the difference is about half as many more people seeing real gains.

What the research says
1 studyThe study found that when people with workout experience follow a personalized training plan instead of a one-size-fits-all plan, more of them see real muscle growth — and the numbers match exactly what the claim says.
