No, fitness needs to consume a lot of oxygen and water. Scientific research shows that people should not eat within one hour before and after strenuous exercise, because it may cause hypoxia in the body and trigger a reaction. Beef jerky still needs to absorb a lot of water in the process of absorption by human body, which makes people feel thirsty. Drink some water before exercise, and don't overeat after exercise. This will not only increase the burden on the gastrointestinal tract, but also be detrimental to the normal operation of the body. Hehe, I wish you success in fitness.
