Stretching
We knew a guy who had knee pains so bad that they woke him up in the middle of the night. Chiropractors wanted to manipulate, surgeons wanted to cut, and even after trying a wide range of solutions, the guy's pains showed no improvement. One day, however, he happened upon this book, learned about a quad stretch that he started doing from that day forward, and almost as immediately as he started the stretch, the pains disappeared. See why we like this book? No hype, but results by the bucket load. 192 pp.
