Your plastic surgeon will always be your best resource when it comes to specific instructions in regards to returning to activities. Generally speaking, best to limit strenuous activity for at least 2 weeks after breast augmentation surgery, assuming you are doing well and there have been no complications. Care should be taken during the first two weeks after surgery not to allow for elevation of heart rate, blood pressure, and/or direct trauma/contact to the chest wall. Generally speaking, most my patients are able to return to lower body exercise at the 2 week post operative mark, wait to lift/run for about 4 to 6 weeks after surgery. Other exercises, involving the pectoralis major muscles, may resume several months down the line, if not longer. In my practice, I would ask that you avoid activity such as tennis or golf for at least two months after surgery. In other words, start slow and "listen to your body" as you gradually progress in intensity/duration of all activities. Best wishes.
