Mark Bell's PowerCast: Dr. Andy Galpin more #musclescience (Part 2/2)

Contributor: Dr. Andy Galpin

This is part 2 of my conversation with Mark Bell and Jim McDonald, we chat about vitamin D, creatine, tracking calories, supplements, probiotics, fiber, fasting, sugar, the post-exercise anabolic window, cold and heat therapy, and low carb diets — breaking down what actually works, what probably doesn't, and what works for some people but lacks proof. We also get into why intentionally choosing hard things: fasting, cold exposure, skipping your pre-workout — training your ability to perform when conditions aren't perfect, and why that carries over into every other area of your life.
