Years ago, when i was so severely debilitated by chronic fatigue and pain, I tried yoga, but it was excruciating, and triggered such severe pain in my hips that I ended up on crutches for several weeks. So then I switched to Tai Chi and loved it. It was perfect for me, and although I've forgotten most of the moves now, I still do the stretching exercises every morning. I found it gentle, yet perfect given all the arthritis that flares up with most other exercises.
