The Claim

Resistance training performed to muscle failure results in greater decreases in repetitions per set over time relative to volitional interruption training among untrained men, suggesting increased fatigue accumulation.

Cause and effect
1 study reviewed
In plain English

When untrained men lift weights until they can't do any more reps, they get more tired over time compared to stopping earlier, meaning their muscles wear out faster.

See the scientific wording

Resistance training to muscle failure causes greater decreases in repetitions per set over time compared to volitional interruption training in untrained men, indicating higher fatigue accumulation.

What the research says

1 study

  1. Study: Effect of Resistance Training to Muscle Failure vs. Volitional Interruption at High- and Low-Intensities on Muscle Mass and Strength

    The study looked at muscle failure training and stopping early in untrained men and found both methods worked about the same for building muscle and strength, so it doesn't support the idea that muscle failure causes more fatigue.
