Anyone who is used to doing aerobic exercise knows that "aerobic exercise" must last for more than 20 minutes to be effective. But why "20 minutes"? A well-known Japanese fitness coach explained that the energy of the human body comes from fat and carbohydrates. At the beginning of exercise, you will consume a lot of carbohydrates first, and then burn fat slowly, and "20 minutes" is the time when the body turns to burn a lot of fat.

In addition, when doing aerobic exercise, it is not time but "load" that affects fat burning. Heavy load aerobic exercise (panting) mainly consumes sugar, while light load aerobic exercise (slightly speeding up breathing and talking to others) consumes fat.

10 minutes of aerobic exercise can burn fat.

It is suggested that as long as you do 10 minutes of aerobic exercise, you can achieve the effect of burning fat. Even after 5 minutes of exercise, you can still achieve the effect of 10 minutes of exercise after taking a break and exercising for 5 minutes.

As for what type of aerobic exercise can reduce fat? Nakano, a famous Japanese fitness coach? James. Xiu proposed in his book "The Lower Body Determines Your Second Life" that high-performance aerobic exercise is a "fast walking method", and a little change in walking style can achieve a more effective oil throwing effect than running.
