The Claim
Low-load resistance exercise training (20-25 repetitions to failure) produces comparable increases in maximal strength during multi-joint movements (21% improvement) as high-load resistance exercise training (3-5 repetitions to failure) in resistance-trained individuals.
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 lighter weights many times until you can't do more builds muscle strength just as well as lifting heavy weights a few times until you can't do more, for people who already work out.
See the scientific wording
Low-load resistance exercise training (20-25 repetitions to failure) produces comparable increases in maximal strength during multi-joint movements (21% improvement) as high-load resistance exercise training (3-5 repetitions to failure) in resistance-trained individuals, suggesting both loading strategies can effectively improve compound movement strength when performed to volitional failure.
What the research says
1 studyThe study found that lifting lighter weights many times and lifting heavier weights fewer times both made people equally stronger in big movements like squats, just like the claim said.
