FWIW, sometimes pain within reason is a good thing. It might mean your body is making progress. Like I said, within reason! Don’t overdo it. Like the old expression No pain no gain. FYI, I go to a gym 4times/week.
I can attest to this! I’ve been gyming for 35 years. Without any doubt, exercise helps me! I don’t use aids in walking at all and have had SCA for 34+ years. My brother doesnt work out and it is so obvious. I get dizzy and it helps 100%. I do cardio and weight train. It works wonders!
