The Claim
In resistance-trained men, performing one, three, or five sets per exercise for eight weeks results in similar increases in maximal strength (1RM squat and bench press) and upper-body muscular endurance, indicating no significant difference in outcomes across these training volumes.
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 men who regularly lift weights, doing one, three, or five sets of each exercise for eight weeks leads to the same gains in maximum strength and upper-body endurance.
See the scientific wording
In resistance-trained men, training with one, three, or five sets per exercise for eight weeks produces similar increases in maximal strength (1RM squat and bench press) and upper-body muscular endurance, indicating that training volume does not significantly influence these outcomes in this population.
In people who already lift weights, the nervous system reaches its maximum ability to recruit muscle fibers during heavy lifts and repeated efforts, so doing more sets doesn't make them stronger or more enduring — their muscles already respond fully at the lowest volume.
What the research says
1 studyStudy: Resistance Training Volume Enhances Muscle Hypertrophy but Not Strength in Trained Men
For guys who already lift weights, doing 1, 3, or 5 sets of exercises for 8 weeks all led to the same strength and endurance gains — so doing more sets doesn’t make you stronger or more enduring, even though it might make your muscles bigger.
