Performing additional sets of resistance exercise does not inherently result in greater increases in muscle size compared to lower volumes.
Practitioners should not assume that increasing the number of sets will always lead to greater muscle growth.
StrongRefutesmedium confidence
Current literature suggests that the performance of additional sets of resistance exercise within a single training session and training week does not inherently result in greater increases in muscle size compared with groups or conditions that perform lower volumes of resistance training.
Why this rating
The claim is based on a review of current literature indicating no linear relationship.

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
