Aerobic exercise can be understood as an exercise that can ensure smooth breathing and relatively low intensity during exercise, and achieve the purpose of losing weight through continuous or repeated exercise. The advantage of aerobic exercise is that it can ensure adequate oxygen intake. Although the effect of losing weight is slow, it helps to enhance the functions of various organs of the body. And as long as there is enough exercise time, the effect of losing weight is not worse than anaerobic exercise. In addition, aerobic exercise with relatively low intensity is more suitable for people with poor physical fitness and the elderly, and will not cause excessive load on the body. For example, it is not suitable for high-intensity anaerobic exercise after meals, but walking for 45 minutes has no effect, and it also helps to promote digestion and help to lose weight and keep fit.

Anaerobic sports can be interpreted as high-intensity, high-frequency and intermittent sports, such as sprinting, weightlifting and diving, which all belong to anaerobic sports. Because of the intensity of anaerobic exercise, its consumption of body energy is also very huge.

At the same time, the fat-reducing efficiency of anaerobic exercise is definitely higher than that of aerobic exercise, but the problem is that anaerobic exercise is not very sustainable. If the anaerobic exercise time is too long, it is likely to cause lactic acid accumulation in muscles, make muscles sore, and may also cause blood vessel damage and hemoglobin exudation, which is not conducive to health.

Therefore, it can be concluded that anaerobic exercise has high short-term weight loss efficiency, but low adaptability, which is not suitable for most people to lose weight and keep fit.
