Yoga is a mind and body practice with a 5,000-year history in ancient Indian philosophy. Various styles of yoga combine physical postures, breathing techniques, and meditation or relaxation.
Here's a book that teaches you how to benefit from yoga, but without the traditional 'woo-woo'. So if you have the attention span of a goldfish, or if you are uninterested in chanting mantras and opening your root chakra, this is it. You will be feeling light as a feather and flexible as a rubber band in no time. You'll be able to touch your toes in no time.
