Editorial Reviews


"Tim Grover is the master of mental toughness. This book is the blueprint for discovering what you are capable of achieving, getting results you never imagined, reaching the highest level of success--and then going even higher." (Kobe Bryant)

"I consider Tim Grover to be second to none in his knowledge of sports training, and he was an invaluable part of my training program. He is a take-charge person, with a deliberate but energetic and enthusiastic technique." (Michael Jordan)

"Tim Grover’s insight into leadership and excellence has taken the greats to the top, and his book will do the same for you. Relentless is about breaking the rules that hold you back and trusting your instincts to take you where you want to be."

(Mike "Coach K" Krzyzewski, Duke University and USA Men’s Olympic Basketball head coach, and bestselling author of Leading with the Heart)

This book will do for you what Tim has done for me--take you to the next level, and show you how to be the best at whatever you do. I have unbelievable trust and faith in him.”

(Dwyane Wade)

"In all the years that I coached, inspired and trained world class athletes there was no better resource to collaborate with than Tim Grover." (Pat Riley, 8-time NBA champion and NBA Hall-of-Fame coach)

"If you compete at anything--sports or business or life--you need this book. No one knows more than Tim Grover about competitive intensity, killer instinct and crushing the other guy. He is the best at what he does: Creating champions." (Charles Barkley)

“Grover finally marches the public behind the curtain of decades of work with the likes of Jordan and Kobe Bryant, a riveting read that balances the illumination of the work of those stars and how it can apply to everyone else. . . Magnificent.” (Adrian Wojnarowski Yahoo! Sports)

Straight up. one of the best books I've ever read. (Jim Rome)

“An opus on successful thinking.” (Sun Sentinel)

"A must-read... Grover calls upon his decades of experience working with the world's most eliteathletes to dissect what it takes not just to succeed, but to be the absolutebest." (

Customer Reviews

This book shows you the mindset of great athletes and how you can apply it to your life.
A lot of cliches are used and it leaves one with the feeling : 'Is that it'....Why write a book and say nothing... ?
If you want to know how they handle their business and "get it done," this book is for you.

Format: Kindle Edition
This wasn't a book. It was a mantra that is repeated for hundreds of pages. There isn't a single strategy in it to improve or accomplish anything. This was the first Kindle book I ever asked to return and receive a refund. It contains no explanation for how he has helped his clients or how you can help yourself in any form or fashion. The 13 traits shared aren't explained or given any sort of methodology. Rather then are all a form of circular reasoning, hence why the book reads like a mantra.

You're a cleaner. This is why you demand the last shot. Why do you demand the last shot? Because you are a cleaner. Why would you pass up the last shot, because you are a cleaner who has belittled or punched a teammate and they didn't sue you so they have earned the title of closer as bestowed by you with your cleaner mentality. Thus you can defer to a closer because you are a cleaner and give them the honor of the last shot.

If none of that makes any sense then you see the problem with the book as that is a summary of how the entire book reads. Cleaners are born, not made and he knows cleaners because he was born a cleaner. If you have to read his book, by definition you would never be a cleaner because a cleaner would be too busy being a cleaner to need affirmation and help to become a cleaner. He trains cleaners because they recognize each other as cleaners and he is a great trainer of cleaners because other trainers aren't cleaners.

Again if you find this hard to read, then you understand the problem with the book.

I am fairly sure that many who are drawn to this book are looking for anecdotes involving Jordan, Kobe and Wade. None here. At least nothing of interest, and the author himself says so by claiming that whatever happens between the client and him stays with them. Professional, but the advertising is very misleading.

With that out of the way, it's yet another one of those motivational books, except it doesn't seek to motivate you but goes on about how he (and Jordan, Kobe, and Wade) is naturally motivated. So are you, it goes on to say, as long as you keep in touch with your true self and not worry about how you are perceived. Then it keeps up this point by arbitrarily dividing people in to three categories: coolers, closers, and cleaners.

If you were looking for some sort of a motivational book, I'd probably give it 3 stars. If you were looking at some 'behind the scenes' stories of what makes great athletes great, including moments of their not-so-visible lives, you really have come to the wrong place and should move on.

Format: Hardcover
Obviously Mr. Grover should be applauded for his personal success however, his ability to communicate his message to an anxious audience is woefully inadequate. It appears you have to hire Mr. Grover personally to obtain the benefits of his experience because any usable information is glaringly missing from this effort.Further, it appears that Mr. Grover is a firm supporter of excess, which may explain some of the less enviable personal traits of his main characters, M. Jordan, K. Bryant and D. Wade. As a Marine, D-1 athlete, coach, father and grandfather, I'll be looking elsewhere to provide advice to those who seek it.

Has some good stories about elite level athletes, but offers zero practical advice on how to raise your level of performance. Not worth the time or money - I stopped reading half way through. Worst book I have read in a long time.

This book never finds its stride. I never did figure out whether it was a biography of Michael Jordan (whom the author seems to have a "man crush" on), a bio of Kobe Bryant or his own autobiographical experiences as a PE coach, or a sports psychology motivation book. There are some nuggets of wisdom interspersed, but then Grover keeps lapsing into his mantra that it's alright for Michael Jordan to be a complete pr*** because he dribbles a basketball better than other people. His term "cleaner" for a "relentless" person never resonates. It doesn't reach the iconic lexicon the author seems to be hoping for. It seems like he's watched "Pulp Fiction" one too many times and is completely enamored with Harvey Kytel's character. "Cleaner" just kept reminding me of what Michael Jordan, Kobe et al would work as in the local high school if they couldn't play basketball, since Jordan's only other talent seems to be losing money at casino gambling tables. His pseudo tough-guy vernacular is also contrived and distracting. Trying to come across as some no-nonsense bad a**, using a liberal sprinkling of "f***," "motherf*r," "a-h**," etc., just makes him sounds weak -- kind of like the gym rats who take a "boot camp" fitness class and suddenly think they know what it's like to be in the Marine Corps. Not very professional. But then again, maybe that's how they're teaching PE teachers to talk these days.

The author also talks about the people who know how to get the job done -- the ones who work late at night closing up restaurants, or other bottom-of-the-rung jobs, and work their way up in life, paying their dues, learning life's lessons and going on to be superstars. Fair enough, good lessons to be learned going that route. Yet none of his prima donna heroes did any of that.
