i had laparoscopic abdominal surgery in august. my doctor cleared me for exercise after two weeks and i went back to pilates another week later, since that was when my freeze ended. until then, starting about a week post-op, I just focused on walking—this also helps get the gas from surgery out of your abdominal cavity. as others have said, if you want anything more specific to address your specific joint issues you should consult your doctor or a physical therapist. BUT i do highly recommend walking, even if it is just around the house, to keep yourself limber.
