Query: Real and Satisfying Exercise

When surgery left me spending much of my time in a wheel chair, I was concerned to find some means of exercise that would keep me in reasonable physical shape. I formerly did T'ai Chi, so it was with interest that I discovered the existence of this videotape. But I had reservations, too; could a seated T'ai Chi form replicate the many benefits of the original thing?So far, although I have used the video for a limited period of time, I am convinced that it provides a good T'ai Chi experience, and real and satisfying exercise. The motions I went through with the instructor were the motions I remembered so well. Even with my limitations I was able to do most of them, and the tape left me with a pleasantly raised pulse rate and a desire to continue using it on an everyday basis. I recommend it highly.
