Why do tai chi?

Karen has done something that answers this question.
When she first started class, Karen's arms were suffering from repetitive strain injury. This was the result of her job.
The joints were stiff, immobile and insensitive.

By working closely with Master Waller, being mindful at work and doing tai chi exercises at home, Karen has managed to totally free up her joints, release tension and ease the discomfort.
The positive effects will persist as long as she continues the ongoing treatment.

Karen and Master Waller are now working to release tension in the sacroiliac, lower back and buttocks. Given the success of Karen's work on her arms, they are very optimistic.

Why do tai chi?
To improve the quality of your life.
