Exercise can lose weight and turn fat into muscle. The key is to see how you exercise. If it is aerobic exercise, such as walking, jogging, skating, swimming, cycling, playing Tai Ji Chuan, dancing and doing rhythmic exercises, these exercises are characterized by low intensity, fast pace and long duration. This kind of exercise, oxygen can not only fully burn (that is, oxidize) the sugar in the body, but also consume the fat in the body, enhance and improve the cardiopulmonary function, prevent osteoporosis, and adjust the psychological and mental state, which is the main exercise mode to lose weight. If it is anaerobic sports, such as sprinting, weightlifting, throwing, high jump, long jump, tug-of-war, push-ups, diving and muscle strength training, these sports are all high-speed and intense sports in the state of "hypoxia". Anaerobic exercise is mostly an exercise with high load intensity and strong immediacy, which is difficult to last, and the time for fatigue elimination is also slow, so that muscles are developed.
