It depends on your workout - and your surgeon.I encourage all of my patients to do some gentle walking starting the day/night of surgery. Most folks aren't very interested in discussing a return to their exercise routine until at least 2 weeks after their tummy tuck with muscle tightening. At that point more moderate walking/easy hiking may be well tolerated. Usually at some point between 4-6 weeks postop, many patients feel ready to get back to their routine. If it's light cardio or weights (jogging, elliptical, light lifting at the gym), I advise them to start slow and build up their strength and endurance gradually. More active workouts (CrossFit, kickboxing, even yoga/pilates) might require a little more time.Check with your surgeon about his/her preferences to help you maintain your results after surgery.Hope this helps, and take care.Dr. Lim
