After accumulating some weight-lifting and sport-related injuries in my early 30s, an older mentor who had been through similar injuries recommended that I read this book. I did find some benefit to the book, but I'd say for the average person doing sports, less than half of it is useful. Anyone who is in a teaching, training, or sports therapy position such as a coach or a personal trainer may find that there are a lot of useful sections, too. I'll keep it on my shelf to "troubleshoot" any aches and injuries I develop in the future, and hopefully the tips I picked up in this book will help me to prevent injuries in the first place
