Exercise prescription for obese patients should be individualized since they are not accustomed to exercise. When we prescribe exercise for obese patients, low impact exercises such as walking, cycling, swimming are recommended. We should pay special attention to obese patients with comorbidities such as hypertension, diabetes, ischemic heart disease or osteoarthritis when we prescribe exercise. For effective weight loss, it is necessary to improve exercise compliance and increase physical activity level.
