Summary

This study said doing 5 to 10 sets of weight training per muscle group a week was just as good for building muscle and strength as doing 15 to 20 sets — and doing more actually made strength gains worse.

Surprising Findings

Higher training volumes (15–20 sets) led to smaller strength gains than moderate volumes (5–10 sets).

Most fitness culture assumes more volume = more progress. This shows excess volume may impair strength development in trained individuals.

Practical Takeaways

If you're a trained lifter, try reducing your weekly sets per muscle group to 5–10 and see if strength improves.
