Because aerobic exercise will disturb the fibers in the body, once aerobic exercise stops, aerobic decomposition will also stop, which is not conducive to the later equipment exercise. Moreover, people first provide energy glycogen in aerobic exercise, and when glycogen is consumed, the body will start to consume the stored energy source (fat). If you do the instrument first, you need to consume energy, which will consume muscle glycogen and liver glycogen. In this case, when we start doing aerobic exercise, we will consume fat directly, which will help us to lose fat quickly. In addition, girls can also do anaerobic, add some strength exercise when reducing fat, which can make fat reduction get twice the result with half the effort. Many girls don't do strength exercises because they are worried that strength exercises will become "muscle girls". In fact, this is also a misunderstanding. Because aerobic exercise will accelerate muscle decomposition. And for women, developed muscles are difficult to practice.
