Before exercise, we must first ensure that the body is in a good state, one of which is to maintain the blood sugar level in a normal state. In the process of exercise, the first energy substance consumed is blood sugar in the body, which is consumed during exercise. Without eating, the blood sugar level is in a low state. Coupled with the consumption of exercise, hypoglycemia symptoms, dizziness, inattention, black eyes, fatigue and so on are bound to appear during exercise. To avoid this situation, it is necessary to take proper carbohydrates and glycogen before exercise to ensure the state of the body during exercise!

The interval must be well controlled, at least when you go to exercise, the food has been basically consumed, otherwise the stomach needs energy to digest the food, and training without complete digestion will cause stomach cramps and nausea and vomiting!
