2895: Should You Train Each Muscle Twice a Week? The Data Says Yes - Here's Exactly Why
Short answer: yes. Training each muscle group twice a week builds more muscle than once a week — the data is clear on this, and Sal, Adam, and Justin break down every reason why in this episode. From how fatigue silently kills your volume to why junk sets pile up when you try to cram everything into one workout, they pull back the curtain on what's actually happening inside your body when you split things up. You'll also learn why total training volume — not just sets, but reps AND weight — goes up automatically when you split your body across two sessions, and why that matters more than almost anything else for building muscle long term. The guys connect the science to real-world scenarios: bad weeks, missed workouts, leg day mental prep, and how to fuel the sessions you want to crush. They also walk you through the brand new MAPS Upper Lower program, a four-day-a-week upper/lower split built around exactly this training philosophy. It's the first four-day-specific program they've ever built, it comes in both male and female versions, and it's 40% off right now during the launch window.
