In this episode of Barbell Shrugged, I had the chance to return and talk about one of my favorite topics: physiological flexibility. Anders Varner and Doug Larson asked some great questions as we dug into the four pillars I use to help people build a more resilient and adaptable physiology—temperature regulation, pH balance, expanded fuel use, and breath work.
We broke down what it means to train your body to handle extremes: staying sharp through big temperature swings, managing pH shifts from diet and exercise, tapping into different fuel sources efficiently, and using breath control as a performance tool. These aren’t just abstract ideas—they translate directly into better performance, faster recovery, and stronger long-term health.
If you want to understand how to push your body further while making it more adaptable, this conversation is one you won’t want to miss.
