　　Aerobic exercise should last for more than 20 minutes to burn fat

　　As long as you exercise, fat is burning. “If you want to lose weight, more than 20 minutes of aerobic exercise is essential. We often hear this, but in fact it is a serious misunderstanding. After you start exercising, the first step is to break down sugar and convert it into energy to support exercise. The next step is to burn fat. However, it does not mean a strictly defined sequence of decomposing sugar in the first 20 minutes and fat in 20 minutes. Just exercising will burn body fat.

　　In a busy life, it is impossible to concentrate on exercise for a period of time, so use the scattered time in work and life to carry out simple exercises. If you add up, you can achieve the same fat-burning and weight-loss effect as in the gym.
