What if the ability to look, feel, and perform at peak capacity wasn't the stuff of lore but instead was within easy reach? Sure, some of us find ways to hit peak performance in one area or another - there are professional poker players, computer programmers, and race car drivers hunched over card games, keyboards, and steering wheels with optimized minds; UFC and NFL gladiators fighting for glory on television with optimized bodies; and monks and meditators roaming the planet with optimized spirits. But in a perfect world, you would be able to have it all: complete optimization of mind, body, and spirit. In Boundless, the New York Times bestselling author of Beyond Training and health and fitness leader Ben Greenfield offers a first-of-its-kind blueprint for total human optimization.
