Welcome @anniekirby, I'm happy to hear your PMR is in remission. Mine is also in remission and I try to do daily exercises to help build my leg strength as well as work on my balance. I do have some Nordic walking sticks to use if I go on a long walk but don't use them for everyday walking. They really help with my balance. Walking is really good too. Here are some exercises I found that might be helpful if you haven't already tried them.
