"Gray's premise is beautiful in its simplicity: Training movement can fix muscles, but training muscles rarely fixes movement. Since all of sport is movement, his 80/20 approach is then astounding in its effectiveness. For the time invested, the FMS and its cousins are the best tools I've seen for producing bullet-proof athletes and pain-free non-athletes in record time." Tim Ferriss, author of the #1 NY Times bestseller, The 4-Hour Workweek Exercise "We have integrated many of Gray's movement principles and corrective strategies into our programs to help accomplish our mission of preserving and maintaining the Commander s combat power. The FMS screening and assessment tools are very useful in establishing the baseline for our performance training system." Mike Strock, US NAVY, Human Performance Consultant "Once a decade comes out a book that you will keep reading, rereading, and crowding with notes until it falls apart. Then you buy a new copy and enthusiastically start over. In the 1990s it was Verkhoshansky and Siff's 'Supertraining.' In the 2000s McGill's 'Ultimate Back.' Enter the 2010s and Cook's 'Movement.' It is a game changer." Pavel Tsatsouline, author of Enter the Kettlebell! --Pavel Tsatsouline, author of Enter the Kettlebell!
