The Claim

High-load resistance training (8-12 repetitions per set) causes greater increases in maximal strength than low-load training (25-35 repetitions per set) in well-trained young men over 8 weeks, with back squat strength improving by 19.6% versus 8.8% and bench press showing a trend toward greater improvement (6.5% versus 2.0%).

What the research says

Supports is higher

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

Challenges
0score

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 heavier weights for fewer reps makes well-trained young men stronger faster than lifting lighter weights for more reps, especially in exercises like squats and bench presses.

  1. Study: Effects of Low- vs. High-Load Resistance Training on Muscle Strength and Hypertrophy in Well-Trained Men

    This study directly tested the same training methods and found that lifting heavier weights for fewer reps made people stronger faster than lighter weights for more reps, just like the claim said.
