Summary
The biggest lie in fitness is that you have to choose between being strong or being fit. In this episode of the Kris Gethin podcast, I join Jen Cohen on her Habits and Hustle podcast to break down why I've dedicated my career to proving that wrong.
We dive deep into the science of preventing muscle catabolism during cardio, the nutrition protocols that support both strength and endurance, and why most people's approach to body composition is fundamentally flawed. I share my personal biohacking stack for reversing biological age, including stem cell therapy, peptide protocols, and the silent meditation retreat that changed everything.
Jennifer Cohen is a leading fitness expert, bestselling author, and host of the Habits and Hustle Podcast. Known for her no-nonsense approach that cuts through industry BS, she's authored multiple books and is a trusted voice in wellness.
