Type 2 diabetes mellitus is a major risk factor for excess morbidity and mortality. The excess vascular risk in type 2 diabetes is attributable both to hyperglycemia1,2 and to other metabolic disturbances associated with abdominal obesity, insulin resistance, and compensatory hyperinsulinemia. Sedentary lifestyle is also a major cardiovascular risk factor,3 and regular exercise attenuates the vascular risks associated with type 2 diabetes.4,5 Aerobic exercise refers to activities such as walking or jogging with continuous, repetitive movement of large muscle groups for at least 10 minutes at a time, whereas resistance exercise refers to activities such as weight lifting that use muscular strength to move a weight or work against a resistance load. Aerobic exercise for individuals with diabetes has been recommended for many decades,6 but the American Diabetes Association only began recommending resistance exercise in 2006.7
