For young active men, doing lighter weights with more reps three times a week for a month might cause less muscle damage than lifting heavy weights with fewer reps, based on a blood test that measures muscle stress.

Measuring the Parameters of Maximum Muscle Strength, Muscle Mass, Muscle Damage in Active Adult Males after Low–Load High–Repetition with High–Load Low–Repetition Resistance Training

Cross-Sectional Study

Human

The study looked at the exact same training methods and people described in the claim, and it found that low-weight high-repetition training really does cause less muscle damage than high-weight low-repetition training.

Similar Assertions

Lifting heavy weights fewer times, three days a week for a month, helps young active men build more muscle and get stronger than lifting lighter weights many times.

Lifting heavy weights to the point of exhaustion three times a week for six weeks makes untrained young men much stronger than lifting lighter weights, even though both types of training build similar amounts of muscle size.
