Aerobic exercise refers to the 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, reaching a physiological balance. Aerobic exercise refers to low-intensity, rhythmic exercise, with a long exercise time (about 30 minutes or more) and moderate or above-average exercise intensity (60% to 80% of the maximum heart rate).

Benefits:

The purpose of aerobic exercise is to enhance cardiopulmonary endurance. In the process of exercise, due to muscle contraction, a lot of energy and oxygen are needed, and the demand for oxygen increases. The number of heart contractions, the amount of blood pumped out each time, the number of breaths and the degree of lung expansion all increase. Therefore, when the exercise continues and the muscles contract for a long time, the heart and lungs must strive to provide oxygen to the muscles and take away the waste in the muscles. And this constant demand can improve the endurance of the heart and lungs. With the increase of cardiopulmonary endurance, the body can engage in longer or higher-intensity exercise, and it is less likely to get tired.

The combustion of gasoline is inseparable from oxygen, so we can also call the work of the engine aerobic exercise. Similarly, human beings burn fuel when they exercise. The "fuels" of human beings are sugar, protein and fat. These "fuels" of mankind are stored in human cells. When you exercise, you will consume these "fuels" to gain motivation.
