Drinking some energy-supplying drinks before exercise, that is, drinks with high sugar content or carbohydrate content, can ensure enough energy during exercise. After exercise, you can add some electrolytes-regulating drinks, such as Poukari Khan, Jianlibao, Gatorade and Pulse, which will make your body function recover quickly. If you want to gain muscle, you can also take a certain amount of protein powder and drink it with water.
