When I started to go to the gym to exercise my muscles, the coach said that I only need anaerobic exercise, because anaerobic exercise is used to exercise my muscles, so every time I go to the gym, I will lift dumbbells to exercise my muscles, and sometimes I will do some push-ups and sit-ups. But if I want to exercise my muscles, I have to eat a lot of food containing protein, such as eggs and milk. Only in this way can you exercise your muscles better.
