About this episode

This episode discusses optimal muscle training frequency for growth and common mistakes in bodybuilding programming.

How often should you train each muscle for maximum muscle growth? The answer isn’t as simple as “twice a week.” In this episode, we break down the science behind training frequency, why more sessions don’t always produce more muscle, and how elite physique coaches actually decide when to increase—or decrease—training frequency. We also discuss volume, specialization phases, recovery, exercise selection, and the biggest mistakes lifters make when designing their training splits. If you’re trying to build more muscle, bring up lagging body parts, or optimize your bodybuilding program, this episode will help you make smarter programming decisions.
