16. JJ Virgin: The Real Reason You’re Not Building Muscle (+ What to Do Instead)

Extend Podcast with Darshan Shah, MD

Ever find yourself putting in the time at the gym, only to feel like you’re barely moving the needle? Or notice that staying in shape seems to get tougher every year? Here’s the thing: muscle health is the backbone of your metabolism, strength, and long-term vitality, but it’s often the missing link in most people’s routines.

In this episode, I’m thrilled to sit down with JJ Virgin. Together, we dive into why muscle matters for more than just strength, how to use high-intensity interval training to hit your fitness goals faster, and practical hacks for optimizing your protein intake—no more wasting time on ineffective routines. JJ Virgin is a leading voice in health and fitness, a best-selling author, and a nutrition and exercise expert. With over three decades of experience, she is dedicated to helping people maximize longevity and metabolic health through science-based, personalized strategies. As a pioneer in the field of powerful aging and fitness for women, JJ blends science and practical advice to promote a strong, active approach to aging.

➡️ If you're ready to understand how to work with your body’s natural strengths instead of fighting against it, this is the episode for you.
