The Claim
In trained females, increasing resistance training volume from 22 to 30 or 38 sets per week over a 12-week period does not result in significantly greater increases in summed lateral thigh muscle thickness compared to maintaining a volume of 22 sets per week.
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.
For women who already train with weights, doing more sets per week—up to 38—does not lead to noticeably bigger thigh muscles after 12 weeks compared to doing 22 sets per week.
See the scientific wording
In trained females, increasing resistance training volume from 22 to 30 or 38 sets per week over 12 weeks does not lead to significantly greater gains in summed lateral thigh muscle thickness compared to maintaining 22 sets per week.
When muscles are trained regularly, they build new protein at a certain maximum rate. After a certain number of workouts per week, the muscles can't make protein any faster, so doing more workouts doesn't make them grow any bigger.
What the research says
1 studyFor women who already lift weights, doing more sets per week — even up to 38 — didn’t make their thighs noticeably bigger after 12 weeks compared to doing 22 sets. More sets helped with strength and one muscle measurement, but not the overall thigh thickness.
