I don't know if you have heard of HIIT. If you often do some fitness exercises or watch some fitness videos, then you can definitely understand what HIIT is. Many fitness bloggers all over the world are doing HIIT fat burning exercise, because they think that HIIT can effectively make their bodies better, so we all know that the weight loss effect of HIIT is very efficient, so why do many people still have no way to lose muscles through aerobic exercise?

For people who exercise regularly, I think the word HIIT is familiar to everyone. You can see the fat burning movement of HIIT on many sports software, but do you know the fat burning movement of HIIT? Let's understand its meaning. Actually, these English letters need to be understood separately. In fact, it is short for high-intensity interval training, and translated into Chinese is high-intensity interval training.

This kind of high-intensity interval training is usually used to exercise your cardiopulmonary function and impact speed. At the same time, if combined with other sports, it can make fat loss efficient, which is more popular in Europe and America. So why are we all trying to do this exercise, but we still can't effectively lose our muscles? In fact, when we do HIIT exercise, because the body will secrete lactic acid at the same time, fat will be converted into muscle protein, and then it will be decomposed and oxidized. So from the point of view of exercise, most of the fat in the body has been converted into muscle, and muscle has no time to digest at all, so this is the reason why HIIT can't lose weight.

Compared with other aerobic exercises, this kind of HIIT exercise is very intense and has an impact on muscles, so if you can keep trying this kind of exercise, you can rest assured that you will not consume muscles while doing aerobic exercise, and HIIT can realize aerobic exercise without losing muscles.
