There is growing evidence that this mind-body practice, which originated in China as a martial art, has significant value in treating or preventing many health issues. It is easy to get started even if you aren't in tip top shape or the best of health. In this low-impact, slow-motion, dance like exercise, you go without pausing through a series of motions with names such as, "Wave Hands like Clouds" or "Grasp the Bird's Tail".

As you move, you breathe deeply and naturally, focusing your attention on your posture and bodily sensations. Tai Chi differs from most other physical types of exercise in several respects. The movements are usually circular and never forced, the muscles are relaxed rather than tensed, the joints are not fully extended or never straight, and connective tissues are gently stretched. Tai Chi can be easily adapted for anyone, from the most fit to people confined to wheelchairs to advanced martial artists.
