As for the intake of carbohydrates before exercise, it should be arranged according to your personal exercise time. If you are used to exercising in the morning, I suggest you eat nothing in the morning, drink some water, then go out to exercise and come back for breakfast after exercise. During fitness, it is recommended to eat less carbohydrates such as noodles, steamed buns and steamed buns, and buy some whole wheat bread with protein foods, such as eggs and milk.
If you exercise in the afternoon and evening, it is recommended to supplement some energy two hours before exercise, but don't eat too much, which will not affect exercise. It's best not to eat anything containing carbohydrates after exercise. It's close to evening, and it's easy to get fat if you eat these again.
