I generally recommend no heavy lifting or strenuous activity (no exercise) for 4 to 6 weeks after tummy tuck. After six weeks, I encourage patients to slowly resume exercise routines *gradually*. Remember, during the six week postoperative period - you will be deconditioned. I do prepare patients do notice some increased swelling once exercise is resumed. Over the next several weeks, this post-exercise edema will no longer manifest. Exercise itself will not help reduce this swelling. If swelling manifests during your workout routine, you may benefit from use of compression garments. But please check with your surgeon with respect to his/her specific recommendations. Enjoy your results!
