The Claim
In young untrained men, 11 weeks of 3-set resistance training leads to a 41% improvement in lower-body strength, compared to a 21% improvement with 1-set training, demonstrating a dose-response relationship between training volume and strength gains in novice lifters for leg exercises.
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're a new guy to lifting weights, doing 3 sets of leg exercises 3 times a week for almost 3 months will get you way stronger than doing just 1 set — like 41% stronger versus 21%.
See the scientific wording
Young untrained men show a 41% improvement in lower-body strength after 11 weeks of 3-set resistance training, compared to 21% with 1-set training, indicating a meaningful dose-response relationship for leg exercises in novice lifters.
Doing more sets of leg exercises pushes muscles to work harder and longer, which forces more muscle fibers to activate and grow bigger over time, making the legs stronger.
What the research says
1 studyWhen new guys lift weights, doing three sets of leg exercises instead of just one makes them much stronger — and this study proves it.
