I have been doing yoga 3/4 times a week for the last four years. I had to stop briefly while I figured out why my body was so sore but once I was diagnosed and on the prednisone I resumed. I do a class called yoga for flexibility and also ball yoga. I love it. I believe it has kept me more agile and flexible. I do still get sore some days as I taper. I started at 20 mg last Aug and am down to 7 now. I also was just diagnosed with severe osteoporosis so have added some weight lifting to my routine. I believe keeping moving has helped .
