When people exercise, nerve cells will secrete a compound called adenosine, which will make people feel tired. Drinking coffee can prevent adenosine from playing its role, improve people's sense of pleasure during exercise, and make people more motivated to exercise. The average exercise time is 1 1%.
Caffeine can also improve our endurance sports ability, which can make us run faster and ride farther. Drinking a cup of black coffee about 20 minutes before long-distance running to lose weight and then drinking more water can improve your nerve excitability and improve the effect of running to lose weight.

Diet before fitness
Eat some high-fiber biscuits, or yogurt, raisins, or fresh fruit between 0 and 2 hours before exercise. This will make you more energetic when you exercise.
If you want to take part in a running race or other races, you should have a low-fat and high-carbohydrate meal two or three hours before the race. Eat something that you are familiar with and easy to digest. Fruit, yogurt, bagels or a bowl of cereal are all good choices.
