Reviews from Amazon.com

“Knowledge is power and it is my hope that others can use this book as a guide to making informed and effective choices, to prevent injuries and maximize workouts."

"Excellent critique of Cross fit's lack of accreditation by any sports training organization or physical therapy association. A book that should be reviewed by anyone considering beginning Cross fit or any other more advanced exercise program. The randomization of exercises and the use of advanced olympic lifts/movements without proper training is discussed in detail. A must read for anyone considering beginning this type of exercise regimen!"

"Love it. Amazing. Read the entire book in less than a day."
