The best way to exercise to lose weight is to carry out low-intensity, rhythmic, long duration, at least more than half an hour of aerobic exercise, such as jogging, brisk walking, dancing, martial arts, jumping rope, swimming and so on. If the time is too short than half an hour, and the intensity is too large, the body cardiopulmonary function is not strengthened, the heart rate does not come up, the body oxygen supply can not meet the needs of the movement, the body movement is anaerobic exercise. Anaerobic exercise process, the body consumes only sugar, fat is not mobilized, so a short period of time exercise can not achieve weight loss, lipid effect. With the extension of time more than 20 minutes or more, the heart rate rises, cardiopulmonary function to strengthen the body’s oxygen supply to adapt to the demand for exercise, to meet the needs of the body, the body is involved in aerobic exercise. In the process of aerobic exercise, the body sugar and fat can be fully metabolized, consume excess calories and fat, play a good weight loss, fat-lowering effect.
