Aerobic exercise means that during exercise, the human body mainly decomposes and metabolizes oxygen, which reflects that the human body exercises physically under the condition of sufficient oxygen supply, and the energy generated by the metabolism of sugar, fat and amino acids is supplied to the body. It is characterized by low intensity, fast rhythm and long duration. The main purpose of aerobic exercise is to raise your heart rate and exercise your heart, which is why aerobic exercise is also called cardiovascular exercise.

Anaerobic exercise means that the human body does some high-speed and strenuous exercise in a short time, but when the human body tries its best to exercise, the oxygen supply is insufficient, or the sugar in the human body can't be decomposed by oxygen, so it has to rely on "anaerobic energy supply", that is, the sugar in the body generates energy in the form of anaerobic glycolysis to supply the needs of the body. Metabolites of anaerobic metabolism can only be sugar, not fat and protein. Therefore, the effect of slimming is far less than aerobic metabolism.
