This book is wonderful and has allowed me to assess what exercises I need to do and how to move, lift, and sit to avoid problems. I have read at least 20 books on back care and this is the ONE!! It is not for those who want a "quick read" as you must read several sections in order and then assess your personal condition. However, the results for me have been truly amazing in about 3 weeks time.
One word of caution: This book is not (nor does it pretend to be) a substitute for getting a proper diagnosis and, if needed, seeing a physical therapist for advice.
Highly recommended.
