Dr. Brad Schoenfeld, PhD is one of the world’s leading researchers on muscle hypertrophy (muscle growth). He is a Professor of Exercise Science at Lehman College in New York, where he directs the Human Performance Laboratory. Over his career, he has published more than 300 peer-reviewed articles, book chapters, and textbooks on resistance training, body composition, and nutrition.

He is the author of Science and Development of Muscle Hypertrophy and The Max Muscle Plan, and has received prestigious honors such as the NSCA Young Investigator of the Year and the Dwight D. Eisenhower Fitness Award. Beyond academia, he has been a personal trainer and natural bodybuilding competitor, which allows him to uniquely bridge cutting-edge science with practical application.

Here's what he knows: the fitness industry has been selling you the wrong story. Not maliciously, but confidently. And most people are paying the price without even realizing it.

In this episode, Brad reveals why so many people are working harder than they need to while missing the basics that matter most. We discuss the beliefs keeping women from reaching their potential, the risks that sneak up when you avoid certain types of training, and what actually determines whether you stay strong and independent decades from now. He also tackles the myths around supplements, workout structure, and whether you're doing enough or too much.

If you're ready to stop spinning your wheels and start training smarter, this conversation will show you exactly where to begin.
