The Claim
In trained females, progressive increases in training volume of two sets per fortnight and four sets per fortnight result in similar improvements in leg press one-repetition maximum and vastus lateralis cross-sectional area over a 12-week period, indicating a plateau effect beyond a minimum volume threshold.
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.
Among women who already train regularly, increasing leg workout volume by either two or four sets every two weeks leads to the same gains in leg strength and muscle size after 12 weeks, suggesting that going beyond a certain volume does not produce additional benefits.
See the scientific wording
In trained females, a progressive increase of two sets per fortnight and four sets per fortnight both lead to similar improvements in leg press one-repetition maximum and vastus lateralis cross-sectional area over 12 weeks, suggesting a plateau effect beyond a minimum volume threshold.
When muscles are trained regularly, they build more protein up to a certain point. After that, adding more workouts doesn’t make them grow any bigger or stronger because the muscle cells can’t use extra stress to make more protein.
What the research says
1 studyIn women who already lift weights, increasing leg workouts by either 2 or 4 extra sets every two weeks led to the same strength and muscle gains after 12 weeks—so doing more didn’t help beyond a certain point.
