Interpretation of results Morbidly obese: very low VO2max, very high percentage of body fat, obese class III BMI, at risk waist–hip ratio, poor flexibility, and is normotensive with treatment. Sedentary by choice: fair VO2max, moderate percentage if body fat, overweight BMI, a good waist–hip ratio, good flexibility, and blood pressure requiring observation if not treatment. Goals Goal for sedentary by choice is to create a program of exercise that at minimum compensates for the risks of the inactive lifestyle and at best prepares them to follow the adult’s requirement for exercise. Goal for the morbidly obese is to increase the frequency and hours involved in the activities of everyday living in order to expend sufficient energy to achieve weight loss, improve mobility, and mitigate cardiovascular risk.
