The Claim
In trained individuals, individualizing weekly resistance training volume based on personal training logs results in greater increases in vastus lateralis muscle cross-sectional area compared to standardized training volume, with a mean difference of 1.08 cm² after 8 weeks of training.
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.
If you adjust your weekly weightlifting routine based on your own workout history, you’ll likely build more muscle in your thigh compared to following a one-size-fits-all workout plan—after 8 weeks, the difference is about the size of a small coin.

What the research says
1 studyThis study gave people different workout plans: one based on their own past workout logs, and one that was the same for everyone. After 8 weeks, the group using their personal logs grew their thigh muscles more—by exactly the amount the claim says.
