This research study will assess the effects of two different programs on weight, body composition, mobility and improved health. Measures of health will include functional abilities, and physical performance. The 2 programs being tested will be provided the same physical activity program which will include aerobic activity and resistance (weight) training. The intervention study will last up to 1 year with follow-up at 6 months and yearly phone calls thereafter.
