The exercise suitable for obese people is to continuously move the whole body muscles and stimulate the heart and lung organs for a long time. Such as walking, jogging, swimming, cycling, aerobic exercise, playing badminton and so on. Weight sports such as weightlifting and explosive sports such as sprinting and tug-of-war are not only ineffective in losing weight, but also harmful to health. Such sports should be avoided as far as possible. It is best to choose low-impact sports such as walking, cycling and swimming to reduce the influence of sports on legs and feet. However, high-impact sports such as running and mountain climbing will cause ankle and knee injuries due to heavy load, so such sports should be avoided in the early stage of sports. Swimming, aerobics and baseball are the best choices to lose weight. Obese children generally like swimming and aerobic exercise, and they can adjust their intensity and speed freely without putting a burden on their hearts and lungs. In addition, taekwondo, baseball or softball (especially catcher) are more suitable for obese children. At the beginning of sports, we should choose some sports that are difficult and easy to master, so that children feel confident and no longer afraid of sports. Encourage children to gradually get close to sports, fall in love with sports, improve their physical strength through sports, and exercise step by step.
