In this episode, I’m sharing a special rebroadcast of my chat with Dr. Mikki Williden all about physiologic flexibility, including how to train your body to handle stress and adapt better. We cover metabolic flexibility, heat and cold exposure, sauna and cold therapy, lactate and buffering systems, plus CO₂ and O₂ tolerance. You’ll learn how these systems connect to boost performance, recovery, and body composition in a healthy, sustainable way.Sponsor:Physiologic Flexibility Certification Course open Monday, Oct. 13 to Monday, Oct. 20: https://miketnelsons.samcart.com/products/physflex/
