Think you need hours in the gym to build muscle? Dr. Michael Israetel, one of the world's leading muscle-building experts, says the fitness industry has been lying to you. In this episode, Adrian Wells sits down with Israetel to expose why most people are wasting massive amounts of time with inefficient routines that actually hurt their progress.
🎯 What You'll Learn: • Why 45-75 minutes per workout is the sweet spot for maximum muscle growth • The 2-3x per week training frequency that beats traditional body part splits • How your muscles actually grow during the 24-72 hours AFTER your workout, not during it • Why doing more than 16-20 sets per muscle group per week can sabotage your results
👤 Perfect for: lifelong learners and anyone who wants to build muscle without living at the gym.
Israetel breaks down the science behind why less can be more when it comes to resistance training. You'll discover the three-day method that's helping people build more muscle in less time, plus the recovery principles that most trainers completely ignore. This isn't about shortcuts, it's about working smarter with evidence-based strategies.
