1, aerobic exercise refers to the human body under the condition of adequate oxygen supply, because the primary energy of physical exercise comes from the oxidation of fat and sugar in the human body, and aerobic exercise is mostly low-intensity and long-term exercise.

2. Anaerobic exercise refers to our high-speed strenuous exercise in the state of "hypoxia". Because the speed is too fast and the explosive force is too strong, the fat and sugar in the body cannot be oxidized and differentiated, and anaerobic energy supply is needed, resulting in excessive lactic acid in the body and muscle fatigue and soreness.
