Mark Bell's PowerCast: Dr. Andy Galpin (Part 1/2)

In this conversation with Mark Bell and Jim McDonald, I talk about the science of muscle physiology, why skeletal muscle is the largest organ in your body, how the body adapts to training, and why no single training methodology has all the answers. We also get into nutrition, fasting, metabolic flexibility, and why being too dogmatic about any one approach is probably holding you back.
