Anaerobic exercise is generally to exercise muscles by doing some weight lifting exercises. In this process, carbohydrates stored in muscles are decomposed because the human body needs to provide energy for the body by consuming carbohydrates. Once the carbohydrates stored in the body are decomposed, the fat in the body will begin to be consumed. Compared with anaerobic exercise, aerobic exercise consumes more fat. So before aerobic exercise, you can consume carbohydrates through anaerobic exercise first, and then consume fat through aerobic exercise. This can get twice the result with half the effort.
