Review
"The title ... lives up to its hyperbolic name by subverting everything you thought you knew about exercise"
--Entrepreneur
"The result was X3 [Bar], a product that is making waves with professional athletes and experienced lifters alike. It's a combination of Dr. Jaquish's passions--science (specifically movement), problem solving, entrepreneurship and inventiveness--come to life."

"I admit I was skeptical of the system in this book. I'm a convert now. I use it two or three times a week, and for only about ten minutes in the morning. I've put on at least four pounds of muscle, and I was already in great shape. I even quit my gym. I save a few hours a day and a few thousands dollars a year, and get better results."
--Tucker Max, 4x New York Times bestselling author
"I can tell you guys, this is legitimate stuff. I'm really impressed with it...If you're a biohacker...you might want to check out the X3."

"Dr. Jaquish's new book lays out the most interesting research and discoveries he uncovered during his process of creating what I consider to be some very smart and innovative fitness tools. He highlights key takeaways about optimizing human physiology through physical interventions, and I would consider it to be a fascinating and illuminating read with good, actionable insights for anyone interested in improving their health and fitness."
--Ben Greenfield, New York Times bestselling author of Boundless, and host of one of the world's top fitness podcasts
"The X3 [Bar] concept described in this book is a great addition to our program. It is joint friendly, and the variable resistance with diminishing range of motion is a game changer. We have not been able to duplicate it with any other equipment. With the crazy NBA travel, it makes for great workouts on the road as well."
--Bill Foran, strength & conditioning coach for the Miami Heat, USA Strength & Conditioning Hall of Fame
"Resistance training with heavy loads is one of most effective ways to build and preserve our vital lean muscle mass. The X3 Bar (the technology/advancement discussed in this book) is a highly effective, time- and equipment-efficient way to safely produce the necessary loads with the added benefit of variable resistance to further stimulate aggressive muscle growth!"
--Shawn Baker MD, orthopedic surgeon, CEO MeatRx.com, X3 bar user and author of The Carnivore Diet, Multi-Sport World Champion
"In a systematic, evidence-based way, Dr. Jaquish has completely changed my understanding of the physiologic effects of exercise, the benefits of variable resistance, and the profound impact of intermittent fasting."
--Raghav Tadepalli, M.D., board certified anesthesiologist, Assistant Chief of Service, Anesthesiology, Kaiser Permanente Riverside Medical Center
"[This] book definitely takes a different approach and doesn't repeat a lot of things that I have ever read before. There are footnotes and there are citations all throughout the book where you are documenting studies."
--Author Hour
