The Claim

Low-load resistance training (25-35 repetitions per set) causes greater improvements in upper body muscle endurance than high-load training (8-12 repetitions per set) in well-trained young men over 8 weeks, with endurance measured by bench press repetitions at 50% 1RM to failure increasing by 16.6% versus a non-significant decrease of -1.2%.

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.

Cause and effect
1 study reviewed
In plain English

Lifting lighter weights many times in a row helps well-trained young men do more push-ups longer than lifting heavier weights fewer times, after 8 weeks of training.
