Before exercising, people need to drink a proper amount of water, but it is absolutely inappropriate to drink too much water. Excessive drinking water before exercise will not only make people want to go to the toilet during exercise, but also affect the speed and progress of fitness, and excessive drinking water will cause excessive gastrointestinal burden.

Therefore, it is recommended to drink 300-500ml of water between half an hour and two hours, once every half hour, 100- 150ml each time.
