Effect of Exercise on Body Composition and Bone Health in Patients With Thalassemia

Exercise for 30 min a day 5x a week with a choice between Aerobic or strength training. Subjects will choose an aerobic activity to perform 3x/week (e.g. brisk walking, hiking, jogging). They will start at 15-20 min/day depending on fitness level and build up by 5 min intervals/week as tolerated to 50 min/day or 150 min/week by 12 weeks. Subjects will choose strength exercises to perform 2x/week, on days separate from aerobic activity. They will start with 1-2 exercises (e.g. squats, lunges, planks with and without resistance) and gradually add exercises to include all muscle groups (arms, legs, chest, back, abdomen). Start with 2 sets of 10 reps, and work up to 3 sets of 15 reps of given exercises.
