At the same time, after a full meal, the digestive system of the body needs a lot of blood to help digest food and absorb nutrients.

Blood supplies digestive system and muscle tissue at the same time, which easily leads to digestive dysfunction, indigestion and exercise effect.
Second, the best time between dinner and exercise.
According to the intensity of exercise, you can take a walk, walk, square dance, Tai Ji Chuan and other light exercises from half an hour to one hour after meals. Moderate exercise such as jogging, weight-loss exercises and cycling can be carried out one to two hours after meals. High-intensity sports such as long-distance running, skipping rope, playing football and basketball should be carried out two to three hours after meals.
According to the appetite, if the appetite before exercise is large, and the food you eat is mainly protein and fat, these foods are difficult to digest, so it is best to exercise for more than two hours after meals. If the amount of meals is small and the food is mainly carbohydrates, vegetables, fruits or liquid food, the interval between meals and exercise can be relatively shortened according to the intensity of exercise.
