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.

Are electrolyte powders actually improving your workouts, or are most bodybuilders paying for something they don't need?

In this episode of the J3 University Podcast, we break down the science behind electrolytes, hydration, sodium, potassium, magnesium, sweat loss, and resistance training. We explain when electrolyte supplements can improve performance, when plain water is enough, and the few situations where adding extra sodium actually makes sense during contest prep or training in extreme heat.

If you're a bodybuilder, physique athlete, or coach looking to optimize hydration and performance without wasting money on unnecessary supplements, this episode gives you the evidence-based answer.

Has science-based bodybuilding started creating more myths than answers?

In this episode, we break down five popular "science-based" training concepts that may be doing more harm than good when taken to extremes.
