Hi @priscillat, My PMR is currently in remission but when it was active I still tried to do some exercise and activities to keep moving. I had the same feeling of my muscles seemed like they are agtrophying. I also had 2 bouts with PMR. The first one was the worst and lasted 3-1/2 years. I didn't exrecise as much the first time around but when it came out of remission six years later I knew I didn't want the weight gain and started making lifestyle changes with more exercises and better nutrition eating habits. I do think it's sound advice not to do heavy lifting and overdo exercising until you ache so I stuck with mild exercising, walking, working in the yard and some moderated resistance training. If you are looking for ideas, this might be helpful.
