Real Stories. Lasting Transformation.

Hear from our clients about their transformational journey.

Shaun Zetlin’s book is unique in that he shares his own struggles, both emotional and physical, and how they led him to be the man he is today. He is not only a Master Fitness Trainer, but an incredibly self aware individual. As such, he is able to make the mind-body connection as no-one else I have encountered has.

 

In his book, Shaun outlines five Master Mantras, all of which spoke to me. However, the one that touched me most was “Believe That You Are Worthy!” As one who has struggled with depression and anxiety as well as eating disorders my whole life, this approach to fitness is refreshing. It has helped me see why my past attempts at fitness may have failed and led me to believe that I deserve to be healthy. Shaun also talks about shame and thus his approach to fitness is never shame-based; something incredibly important to me.

 

Throughout, Shaun makes you feel he is on your side with his judgment-free attitude. His enthusiasm is palpable. He truly wants each of us to be the best version of ourselves.

Shaun Zetlin is the real deal. He is an expert fitness trainer. His knowledge of how the body works and how best to care for it are beyond compare. This books supports the intertwined emotional piece. Shaun is brave and reveals the work he has done to overcome trauma. Through his work he has crafted a new gym bag that finally ties how our emotional worlds impact self care. He reinforces the idea that we are all where we need to be right now. I turn to his emotional guidance techniques for strength, in particular, using visualization to help focus before an exercise and move fear to positivity. This book is important and Shaun is a trustworthy guide. He helps you become open to more than physical power. Don’t miss the opportunity to progress to a new level of fitness - both physical and emotional. Thank you!

Shaun Zetlin's book has helped me add an important piece that's been missing from my workouts--the emotional component. As a Master Trainer, he has incredible knowledge of the ways to strengthen the body--his exercises and fitness progressions are top notch. But in this book, he takes you to another level to make you stronger in both body and mind. Shaun's Master Mantras and Emotional Guidance Techniques help you visualize and move toward a greater self. He shares honestly about his journey toward his own fitness, which is something I really appreciate in a self-care book. He's worked through his own struggles and now brings that knowledge and experience to the table. You can trust him to help take you on your own journey.

-Rebecca F

“I have been training with Shaun for the past eleven years. As a result, my body has completely changed- for the better, of course! I have great muscle definition- back, abs, arms- and am one of the strongest women in the gym. Shaun has helped me achieve my goals with his innovative workout routines. The workouts he designs are both challenging and fun. He is continually supportive and really helps me be my best. I can't praise him enough!”
