How many days a week should you work out to build muscle — and is a 6-day workout plan in the gym actually better than training 3 days a week? We put over 200 lifters through a 10-week experiment comparing a 3-day vs 6-day push/pull/legs split, plus a third group that packed the full 6-day volume into three full-body workouts. The results reveal some important lessons about how often you should work out, how many times a week you should work out each muscle group, and when more training stops paying off. Here’s what we found, what the best workout split actually is, and how to tell if some of your sets are being wasted.
