How often should you train a muscle each week?
The short answer
A meta-analysis of 25 studies found no meaningful advantage of higher frequency for muscle growth when training volume was equated.
In practice
Use frequency to make your week workable. If you dislike long sessions, you can spread the work over more sessions. If you have few free days, you can choose a different structure.
The nuance
This does not mean that an unlimited amount of work in one session is just as good. The conclusion is limited to the frequencies and programmes studied; recovery and feasibility remain relevant.
