Tai Chi is an ancient Chinese martial art practiced in many styles. The “sun” style, which is the form Andy will be offering in Hampden, has been the subject of rigorous scientific studies that reveal its health benefits, including cardiovascular support, improved muscle strength and flexibility, and increased balance for fall prevention. The practice entails a fluid movement and flow produced through the integration of mind and body. It has in fact been called “meditation in motion” and that phrase probably captures the essence of the practice better than any other. It is about balance, both physical and mental.
