Four out of five people in North America suffer serious lower back pain at some point, according to Vijay Vad. A sports medicine specialist and back-care adviser to professional golfers and tennis players, he asserts that more than 80 percent of lower back pain sufferers can heal with his Back Rx program alone. It's a well-thought-out, comprehensive program; it includes three series of exercises featuring, among other things, supine variations of selected poses and the Sun Salutation sequence. The book also provides a thorough explanation of how the back works, how to avoid and recover from injury, and how to cultivate back health in general.
