I am in my 3rd bout of PMR. My first was in my 50’s and I was an avid exerciser. My rheumatologist at that time said I should do range of motion exercises, but no weights over 2 pounds due to risk of tendenitis. I continued with aerobic classes, walking rather than running, light weights. I did get tendonitis twice from overdoing and benefited from Physical Therapy. I am now 73 and on my 3rd bout of PMR. I walk 60 minutes a day and do an on-line aerobic class with light weights 2-3 times a week. I think the range of motion exercise is really good, but I have avoided heavy weights. I have talked with physical therapists, but I often have to explain what PMR is.
