Some aerobic exercise is likely to be needed to appropriately metabolize and store fat.
To date, there are some small studies that suggest benefit to body shape through exercise. We are hoping more data will support this notion. However, please be aware that exercise, like other interventions, should be monitored to assure that you get maximum benefit at minimum risk. A physical therapist may be able to provide you with an evaluation of your current exercise and assist you in designing a program that benefits you. Then, head to the dietitian periodically to quantify body composition and any body shape changes.
