From Good to Great to Unstoppable

This book can be downloaded and read in Apple Books on your Mac or iOS device.


For more than two decades, legendary trainer Tim Grover has taken the greats—Michael Jordan, Kobe Bryant, Dwyane Wade, and hundreds of relentless competitors in sports, business, and every walk of life—and made them greater. Now, for the first time ever, he reveals what it takes to achieve total mental and physical dominance, showing you how to be relentless and achieve whatever you desire.

Direct, blunt, and brutally honest, Grover breaks down what it takes to be unstoppable: you keep going when everyone else is giving up, you thrive under pressure, you never let your emotions make you weak. In “The Relentless 13,” he details the essential traits shared by the most intense competitors and achievers in sports, business, and all walks of life. Relentless shows you how to trust your instincts and get in the Zone; how to control and adapt to any situation; how to find your opponent’s weakness and attack. Grover gives you the same advice he gives his world-class clients—“don’t think”—and shows you that anything is possible. Packed with previously untold stories and unparalleled insight into the psyches of the most successful and accomplished athletes of our time, Relentless shows you how even the best get better . . . and how you can too.

From Publishers Weekly

Jan 28, 2013 – Grover ( Jump Attack) spends half of his second book making a sales pitch for his sports-performance training services (at Attack Athletics in Chicago), and the other half lamenting the fact that most people are little more than slackers. The book is written in an unremittingly abrasive style ( When people rip me for being an asshole... it means I m on a level they can t attain ) that s bound to irk some as much as it inspires others. Grover explains the differences between three types of individuals Coolers, Closers, and Cleaners whose competitive focus and passion are, respectively, good, great, and unstoppable. A Cleaner is the most intense and driven competitor imaginable, someone whose ultimate success comes from tapping into his or her dark side and acting on instinct. Grover builds the book around the Relentless 13, a baker s dozen of Cleaner characteristics that can be applied both on and off the field; they include attacking opponents weaknesses, being feared more than liked, and never recognizing failure. He must know what he s talking about Grover is, after all, Michael Jordan s personal trainer, and he served as the director of sports performance for the United States 2012 Olympic basketball team but his approach is truly, relentlessly irritating.
