I started to exercise recently, and I felt more and more tired after a week, and my strength was not as good as when I first started. Why?
It depends on your age. If you are young, personally, I think your fitness is definitely just a small matter, but it is really good for strengthening shaping. In addition, protein and carbohydrates should also be supplemented. As long as it is not greasy, it is best not to feel hungry often. Fatigue may also be physical endurance. It is recommended to take a proper rest for two days so that the muscles are not tired.
