During training, you sweat, water leaves the body, and the electrolyte balance is disturbed. It is logical that thirst arises: the body needs to replenish the loss of fluid . Drink during and after exercise . It will absolutely not do any harm.
But do not pour in liters of water: it is enough to take a couple of small sips about once every 10 minutes . From a large amount of water during exercise, you may start to feel nauseous, pressure may increase, and your health will worsen. After training, also do not rush to drink water in large volumes, drink in small portions.
Sometimes, even from a small amount of water, stomach discomfort and seething may appear. If this is the case, don't drink the water, just rinse your mouth and spit it out .
Instead of water, you can try drinking isotonic . This is a special type of sports food that restores the balance of electrolytes and replenishes the loss of fluid in the body. It is especially useful for runners.
It is very important to listen to your body, it will not deceive. If you get thirsty, you need to drink!
During exercise, a lot of sweat is released, and with it salt. Therefore, it is logical that after each lesson it is necessary to replenish the water-salt balance, otherwise the body will become dehydrated.
Moderate and gradual water intake after training will only be for YOU FOR GOOD!
I slightly disagree with the answer above. Naturally, during training, it is necessary to replenish fluid reserves in the body, since you are actively losing it, which adversely affects the processes in your body, but drinking two to three liters is clearly too much (especially during intense but short workouts lasting up to 45 minutes) ... Such an amount of fluid will provoke a rather sharp increase in blood volume, which, in turn, will provoke jumps in blood pressure. You need to make sure that there is enough fluid in the body before and after exercise, and during exercise, replenish it in small, even portions. This is the first reason. And the second is a banal inconvenience. Both strength and cardio exercises are much harder to do when you've drunk two to three liters of water. For this reason, professional athletes during training and competition do not allow themselves to drink a lot, but only rinse their mouths to kill the urge to drink, but at the same time drink quite a lot of fluids in the periods before and after exercise.
Let's start with the fact that during training, whether it be strength or cardio load, all metabolic processes in the body are accelerated, and if you move actively enough, sweating will occur and the human body will lose a sufficient amount of water. It is recommended to drink 1 to 3 liters of water per workout, depending on your weight (conditionally). Since the human body is quite inert, the feeling of thirst is already a "wake-up call" to the fact that your body is dehydrated and needs a certain amount of fluid. Therefore, try not to bring the body to such a state, but after each approach or every 10-15 minutes take a few sips of water.
