Tai chi is an exercise system in the most practical sense. You can achieve so much by learning even a few basic things and practicing consistently. Your body can benefit physically, mentally, and energetically—from better circulation, stronger posture, clearer concentration, better memory, and feelings of well-being and much more.
Tai chi is also meditative ... ideal for tapping into skills of observation and concentration that everyone already has developed in life. Learn to move with precision to obtain the very best benefits that tai chi offers. Focus your attention on a point in your body and move from there.
