Another book/person I'd recommend HIGHLY is Kelly Starrett. He recently did a 2 day seminar on Creative Live about resolving pain, preventing injury and optimizing athletic performance. He's also coming out with a book at the end of April called "Becoming a Supple Leopard". You can check out a 50 page preview of the book below:
