MAPS Abs & Butt is still 40% off: If your goal is a stronger, rounder butt and visible abs, this episode gives you the programming logic, the exercise selection, the rep ranges, the rest periods, and the mindset shift you need to actually make it happen. In this episode: • Rest periods are what make strength training strength training: resting two to four minutes between hard sets trains the energy system tied to muscle growth, while cutting rest short shifts you into aerobic, stamina-based work that does NOT build the butt • A study in the Journal of Applied Physiology...

In this episode the guys break down rep speed — slow reps, fast reps and pause reps — and what the data actually says. They cover why saying it doesn't matter for hypertrophy misses the nuance completely, why injury risk alone makes rep speed matter enormously, why slow reps are essential for mind muscle connection and targeted esthetics, when moving fast matters for performance and everyday functionality, and why the novelty effect of switching rep speeds over time likely builds more muscle long term. Adam also shares why he does fasted cardio even though studies say it doesn't matter for fat loss — and why all the behavioral cascades it creates are the real reason it works. They cover the explosive growth of the electrolyte powder market (LMNT went from $7 million in 2020 to $206 million in 2023 and created the category), reading Love and Respect by Dr. Emerson Eggerichs and why respect and love are fundamentally different needs for men and women, the challenges vegans face hitting protein and why Organifi plant protein is the best vegan protein they've used, and the upcoming Mind Pump pickleball tournament. Then they coach live callers submitted through mplivecaller.com.
