The Claim
In untrained young men, six weeks of resistance training performed twice weekly at 8-repetition maximum intensity results in measurable increases in strength for both knee extensors and elbow flexors, with no difference in outcomes between one and three sets per exercise.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
In untrained young men, doing resistance training twice a week for six weeks at a weight they can lift eight times increases strength in the quadriceps and biceps, whether they do one set or three sets per exercise.
See the scientific wording
For untrained young men, six weeks of resistance training with two sessions per week using 8-repetition maximum intensity produces measurable strength gains in both knee extensors and elbow flexors, regardless of whether one or three sets are performed.
When someone lifts weights, the brain sends stronger signals to the muscles, causing more muscle fibers to turn on and fire faster, which makes the person stronger without needing bigger muscles.
What the research says
1 studyThe study found that doing three sets of leg exercises made people stronger than doing just one set, but for arm exercises, one set was enough. So, the claim that it doesn’t matter how many sets you do is wrong — for legs, more sets help more.
