Thank you for your question. Every surgeon will have his/her own preferences as to recovery for specific procedures. I have patients wait at least 3 to 4 weeks before running or exercise. It's best to be sure that everything is healed. There is always a chance of causing bleeding if you start much before that time. When you start, listen to your body. You will be a little out of condition and a bit sore. But you will get back to where you were before surgery very quickly.
Plastic surgeons may vary in their recommendations. It's always good to see what your surgeon's protocol would be. I advise my patients to take it easy for a week (no sex, for example) so as to minimize their chance of postoperative bleeding. I further advise that they can return to the treadmill by the 21st day. I hope this information helps. For more information on this and similar topics, I recommend a plastic surgery Q&A book like "The Scoop On Breasts: A Plastic Surgeon Busts the Myths."
