Now that people's living standards have improved, more and more friends want to keep fit through exercise. People pay more and more attention to the knowledge and concepts about sports and fitness. Maybe most fitness enthusiasts just know the surface, but they don't. Aerobic exercise and anaerobic exercise are divided according to whether the energy of muscle contraction during exercise comes from aerobic metabolism or anaerobic metabolism. Aerobic exercise, also known as aerobic metabolic exercise, refers to physical exercise carried out by the human body under the condition of adequate oxygen supply. That is to say, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance. So it is characterized by low intensity, fast pace and long duration. It is required that the exercise time should not be less than 1 hour, and it should be carried out 3 to 5 times a week. This kind of exercise, oxygen can fully ferment the sugar in the body, 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 of fitness. Common aerobic exercises include: walking, jogging, skating, swimming, cycling, playing Tai Ji Chuan, dancing, doing rhythmic exercises, etc. Therefore, if you are overweight and want to lose weight through exercise, you'd better choose aerobic exercise, such as jogging and cycling. Not only can it play a good role in consuming body fat, but it is also simple and easy to do. Therefore, if you want to lose weight through exercise, you should first consider taking part in some aerobic exercise.

The so-called anaerobic exercise refers to the high-speed strenuous exercise of muscles in the state of "hypoxia". Such as running, weightlifting, throwing, high jump, long jump, tug-of-war, muscle strength training and so on. Because the speed is too fast and the explosive force is too strong, the sugar in the human body cannot be decomposed by oxygen, so we have to rely on "anaerobic energy supply". This kind of exercise makes the body produce too much lactic acid, which leads to muscle fatigue, muscle soreness and shortness of breath after exercise. If you want to make your body stronger, you can go to the gym to take part in anaerobic exercise.
