Exercise increases the blood supply to skin and therefore, exercise is useful in improving the grafts survival and its blood circulation. As a result, gentle exercise such as jogging, mild weight lifting(a few kilograms) can be undertaken after 24 hours from the surgery. Contact exercises such as football and basketball and heavy lifting and fast running can be started from one week after the surgery when the grafts are integrated with the skin. Before one week, there is a possibility of physical damage to the grafts.
