The Claim
In untrained young men, low to intermediate repetition resistance training (3-11 repetitions maximum) produces greater muscle hypertrophy compared to high repetition training (20-28 repetitions maximum), with significant increases in cross-sectional area for types I, IIA, and IIB muscle fibers observed only in the low and intermediate rep groups after 8 weeks.
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.
Lifting weights with fewer reps (3-11) builds more muscle than doing lots of reps (20-28) in young guys new to training, especially after 8 weeks.

Low to intermediate repetition resistance training (3-11 repetitions maximum) produces greater muscle hypertrophy compared to high repetition training (20-28 repetitions maximum) in untrained young men, with significant increases in cross-sectional area for types I, IIA, and IIB muscle fibers observed only in the low and intermediate rep groups after 8 weeks.
What the research says
1 studyThe study tested the exact same workout methods and found that doing fewer reps with heavier weights built more muscle than doing many reps with lighter weights, just like the claim said.
