The Claim

Increasing resistance training volume beyond 40–60 sets per week does not improve maximal strength gains in trained male athletes and is associated with a small but statistically significant reduction in deadlift strength, with no significant difference observed in back squat or broad jump performance.

Cause and effect
1 study reviewed
In plain English

For trained male athletes, doing more than 40 to 60 resistance training sets per week does not lead to greater increases in maximal strength and may slightly reduce deadlift strength, while having no measurable effect on back squat or broad jump performance.

See the scientific wording

Increasing resistance training volume beyond 40–60 sets per week does not improve maximal strength gains in trained male athletes, as evidenced by no significant difference in back squat or broad jump performance and a small but statistically significant reduction in deadlift strength with higher volume.

Why this might work

When athletes do too many heavy lifts in a week, their nervous system gets worn out and can't activate muscle fibers as strongly, making it harder to lift maximum weight even if muscles are big.

  1. Study: Exploring the Upper Limits of Resistance Training Volume for Muscle Hypertrophy and Strength in Trained Athletes

    For strong athletes, doing more than 60 weightlifting sets a week doesn’t make them stronger in squats or jumps, and might even make their deadlifts a little weaker compared to doing about 40 sets.
