For over twenty years, Michael Jordan, Kobe Bryant, Dwyane Wade, and hundreds of other fierce competitors in sports, business, and every other field have turned to famed trainer Tim Grover to help them reach their full potential. For the first time, he lays out the steps to complete mental and physical supremacy, teaching you to be unrelenting in your pursuit of success.

Grover is direct, harsh, and brutally honest as he lays out the requirements for unstoppability: you persist when others give up, you flourish under stress, and you never allow your emotions to weaken you. In “The Relentless 13,” he lays out the core characteristics held in common by the world’s greatest athletes, businesspeople, and performers of all stripes. If you’re looking to learn how to trust your gut and enter “The Zone,” how to maintain command in any circumstance, and how to exploit your opponent’s vulnerabilities, then go no farther than Relentless. Just “don’t think,” as Grover tells his A-list clientele, and you’ll see how easy it is to achieve your goals. Relentless reveals how the greatest become better… and how you can, too, with never-before-told anecdotes and unmatched insight into the minds of today’s most successful and accomplished athletes.
