During physical training it is important to keep your body hydrated, to avoid injuries and dehydration problems that can cause a lot of damage to health. Much is said about drinking water during physical activity, but it is important to drink water before and after physical activity. This is because drinking water before exercise allows the individual to start exercising with an adequate level of hydration and drinking water after exercise allows the individual to reestablish the balance of water and electrolytes, which is essential for the body's recovery process.
