glycogen

In order to provide, when glycogen is insufficient, it will be consumed.

fat

Protein in the body is a structural substance, which is eventually consumed. So when you exercise your muscles, you will lose fat.

I have been working out, too. I remind you that you must pay attention to nutrition when you exercise. If you exercise too much and don't replenish enough energy, your muscles will be consumed. Pay special attention to the supplement of high-quality protein, such as egg white and lean beef, and eat more fruits, which can supplement minerals and sugar and help to balance water and salt in the body. It is good to eat a banana half an hour before exercise.

I hope you are satisfied with it.
