The Claim

High repetition resistance training (20-28 repetitions maximum) produces greater improvements in local muscular endurance compared to lower repetition regimens in untrained young men, with the high rep group showing the most improvement in maximal repetitions at 60% of 1RM after 8 weeks of training.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

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 untrained young men build more muscle endurance than lifting heavier weights fewer times. After 8 weeks, they can do more reps before getting tired.

What the research says

  1. Study: Muscular adaptations in response to three different resistance-training regimens: specificity of repetition maximum training zones

    The study shows that doing lots of reps with lighter weights helps people last longer during exercise, just like the claim says.
