Hi @paelwell, You will notice that we moved your post to an existing discussion - PMR and exercise: What helps you?: https://connect.mayoclinic.org/discussion/pmr-and-exercise/ so that you can learn what other members have shared. It's good to see that you already have a response from @froehlich22. I too have experienced the "next day" effect after over doing it with exercise or activing when my PMR was active. The key for me was how much activity is too much and I'm not sure I ever figured that out 🙂
