T ai Chi is a 2,000-year-old Chinese martial art that, according to ABC News, is taking America by storm. It is the most popular form of exercise in the world today, practiced by an estimated 20 percent of the world s population. With its unique ability to heal on many different levels - physically, mentally, emotionally, and spiritually - T ai Chi has demonstrated its health benefits by being linked with everything from slowing the aging process and increasing balance and flexibility to lowering stress levels and enhancing the body s natural healing powers. The Complete Idiot s Guide to T ai Chi & QiGong Illustrated, Third Edition , will add to what is already the most comprehensive and illustrative book on the subject by being the first to offer a DVD complementing the 300 illustrations in the book by demonstrating a complete T ai Chi exercise consisting of 64 groups of movements.
