The Claim
In intermediate-trained women, performing one repetition per set with 70–85% 1RM twice weekly for 8 weeks improves maximal strength but does not maximize gains in heavy-load strength or muscle hypertrophy compared to higher fatigue protocols.
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.
In intermediate-trained women, doing one repetition per set at 70–85% of maximum strength twice a week for eight weeks increases maximal strength but does not produce the greatest gains in strength under heavy loads or muscle size compared to protocols that induce higher fatigue.
See the scientific wording
In intermediate-trained women, performing only one repetition per set (0% velocity loss) with 70–85% 1RM twice weekly for 8 weeks improves maximal strength but is insufficient to maximize gains in heavy-load strength or muscle hypertrophy compared to higher fatigue protocols.
Doing just one repetition per set with heavy weights makes the nervous system better at turning on muscles quickly, which increases maximum strength. But because the muscles don't get tired enough, they don't experience the chemical changes needed to grow bigger or get stronger under very heavy loads. More repetitions that push muscles to fatigue trigger chemical signals that build muscle and improve strength under heavy loads.
What the research says
1 studyIn trained women, doing just one bench press per set makes you stronger, but doing more reps until you slow down makes you even stronger and builds more muscle. So, one rep helps, but more reps are better.
