Does anyone go on a regular basis to a fitness club? I feel compelled to do something other than walk for 1 hour per day. I can feel myself getting in worse shape. Has anyone gone to a place like "Curves" or any circuit training gym? I am afraid to commit to this as I feel that I have already had the workout without the exercise. Can our muscles be agravated by exercise? I have sciatica Or piriformus syndrome if you ask both my Fam Dr. and Chiro. Two conflicting opinions. My chiro says don't exercise until my condition improves and my fam doc thinks back exercises will work leaving me in the dark.
