I have joined a health club and managed to swim 200 metres at a time. Could do more, but my arthritic shoulder complains. I have also started using the static bikes and have had a walk on the treadmill. I have put on 15kg since I got PMR last year and desperately need to get rid of the excess - apart from anything else, my wardrobe is full of garments that I can't wear at the moment! Now on 4.5mg of pred and responding well to the reduction. I am still getting very tired and find myself glued to my chair every evening. I'm taking OEP but is there any other supplement that would boost my energy?
