While each patient's postoperative instructions may be different due to technique of the surgery and/or thoughts of the surgeon, I can only tell you what I tell my patients. I've been using the rapid recovery technique for 20 years or so and we tell our patients to lift their arms over their head even before they leave the recovery room and have never seen a problem coming from those instructions. While jumping jacks would not be the best idea, for my patients, lifting of the arms should not be a problem. We do tell them however, to avoid squeezing the arms together to put pressure on the pectoralis muscle for a few weeks. Hope that's helpful.
