Abdominal fat increases by 300 percent between age 25 and 65— while muscle mass decreases by 20 percent between age 40 and 60. Increased abdominal fat promotes inflammation and impairs blood sugar regulation— both of which increase the risk of heart disease and type 2 diabetes. A review of literature by Harvard University researchers concluded that weight training reduces abdominal fat and inflammation and increases muscle mass. Weight training does not burn as many calories as aerobics. However, muscle mass is an important measure of blood sugar control. Weight training is a critical exercise for middle-aged and older adults because it preserves muscle mass, prevents abdominal fat accumulation, decreases inflammation and promotes blood sugar control.
