Many of us spend hours upon hours in the gym to sculpt our physiques. But just how many sets will maximise our results for each muscle group?

If your goal is to build muscle, Dr Mike Israetel just might have the answer.

Dr Mike is perhaps the world’s most famous and influential exercise scientist, at least in the sphere of social media.

Before he became YouTube famous, Dr Mike was publishing excellent blog content for RP Strength (Renaissance Periodisation), mostly focusing on building muscle. He developed several concepts to map training volume landmarks for muscle growth, including minimum effective volume and maximum recoverable volume.

This article explores these principles and outlines how many weekly sets are optimal for each major muscle group to maximise growth.

Training Volume Landmarks

Dr Mike discusses six different training volume landmarks, which are defined below.

These concepts are specified in the context of a whole-body training program. Think about it, if you only ever train your arms, then they’re going to be able to handle a lot more volume than if you train ten different muscle groups equally.
