The benefits of exercise to the body are described in the following list of exercise methods. In the treatment of diabetes, exercise therapy is an important part, especially for elderly patients and obese patients. The importance of exercise in the rehabilitation of diabetes was recognized early in Chinese medicine, and the “Treatise on the Origin of the Diseases” of the Sui Dynasty and the “Secret Principles of Wai Tai” of the Tang Dynasty both documented physical therapy for the disease of thirst. Since then, it has been discussed by medical practitioners in all generations. By the middle of the 18th century, some famous foreign medical doctors also began to advocate that diabetic patients should do appropriate physical activity, and listed physical activity, diet control and medicine as the three major treasures in the treatment of diabetes. Some patients with mild diabetes can achieve blood glucose control by only adhering to physical exercise and combining it with diet control. （All diabetic patients undergoing exercise therapy should be given a comprehensive medical history and physical examination, especially for patients over 35 years of age or with a long course of disease.
