I had frequent pain and throbbing on the side of one knee when I'd run, more times than not...turned out to be i.t. band syndrome, and it hung around for over two years. Bothered me when trying to bike sometimes too. I bought a brace, and took pain meds, neither of which helped much. The ideas in this concise manual did however.
Anyone who runs a lot or works out with regularity should get this book. If you've never had i.t. band syndrome, this is a good exercise approach to use. Very all-inclusive guide for protecting yourself, and making the i.t. syndrome heal up if you've had it strike.
