The Claim

In trained men, a resistance training volume of 5 to 10 sets per muscle group per week over 24 weeks is associated with significant improvements in muscle strength, while volumes of 15 to 20 sets per muscle group per week do not provide additional strength gains.

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If you're already fit and lift weights, doing 5 to 10 sets per muscle group each week will make you stronger—but doing more than that (like 15 to 20 sets) won't make you any stronger, no matter how hard you push.

See the scientific wording

In trained men, resistance training volume of 5 to 10 sets per muscle group per week is associated with significant improvements in muscle strength over 24 weeks, with no additional benefit observed at higher volumes (15–20 sets).

What the research says

1 study

  1. Study: Evidence of a Ceiling Effect for Training Volume in Muscle Hypertrophy and Strength in Trained Men - Less is More?

    In trained men, doing 5 to 10 sets of weight training per muscle group per week gave the best strength gains — doing more (15–20 sets) didn’t help any more and sometimes made progress worse.
