The Claim
In trained women undergoing 24 weeks of resistance training, performing 20 sets per muscle group per week was associated with smaller improvements in muscle strength and size compared to lower-volume programs (5–10 sets), suggesting that excessive training volume may be less effective for hypertrophy and strength gains.
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 women who already work out do too many sets each week, they might gain less muscle and strength than if they did fewer sets.

What the research says
1 studyStudy: Evidence for an Upper Threshold for Resistance Training Volume in Trained Women
The study found that women who did more sets per week didn’t get stronger or more muscular than those who did fewer sets—doing too much might actually be less effective.
