On average what is the most common rep range that shows to have the best muscle mass gains, i hear alot of pro bodybuilders are in the 8-12 rep range, while powerlifters do 1-3 reps for strength, some like khali muscle do up to 30 reps which i didn't think could build much size. What rep range to you is the best for building mass and what rep ranges do the pros use.
Best rep range for building mass?
