"This book takes practical, real-world, time-in-the-trenches thinking to a whole other level. It’s not often I come across a training manual that teaches you how to eliminate chronic pain, balance your hormones, detox your body, maximize fat-burning efficiency, and even hack your brain waves. This truly is the last book you’ll ever need in order to master endurance, health, and life." Author: -Chris “Macca” McCormack, Ironman World Champion
