The Claim
When training volume is increased beyond habitual levels (e.g., from 18 to 33 sets per week per muscle group), no statistically significant difference in muscle hypertrophy, as measured by cross-sectional area, is observed, despite higher absolute 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.
Doing more sets at the gym than you're used to—like going from 18 to 33 sets a week per muscle group—doesn’t make your muscles grow significantly more, even though you might see a little more growth overall.
See the scientific wording
Increasing training volume beyond habitual levels (e.g., from 18 to 33 sets/week per muscle group) does not produce statistically significant differences in muscle hypertrophy when measured via cross-sectional area, despite higher absolute gains.
What the research says
1 studyThe study found that doing more sets didn’t make muscles grow much more after a certain point — even people doing the most sets didn’t get significantly bigger than those doing fewer sets, so going way overboard probably doesn’t help.
