"The X3 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 and conditioning coach for the Miami Heat, USA Strength and Conditioning Hall of Fame

"This book will no doubt be controversial, but the results were evident when I applied the osteogenic loading method for six months to myself. I gained strength in all my lifts and achieved new personal records. But more importantly, my research applying Dr. Jaquish's innovations will give information to the aerospace industry. This method could perhaps be modified for long-duration space flight to avoid strength and bone density loss in a microgravity environment."

"Musculoskeletal health is vital to disease prevention, function, and longevity. 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

"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."
