Exercises Illustrated: Ancient Way to Keep Fit

Chi gung is a 3,000-year-old physical discipline that practitioners consider to be more essential to health than cardiovascular exercise. The ancient system, called the "internal martial arts," emphasizes improving the life force flow, chi, by opening the body's energy centers. These simple exercises derive their power from repetition. They are illustrated in more than 300 watercolors based on ancient Chinese scrolls and cave paintings.
