Is ready: you use sportswear, has a good footwear and a good song already flowing through your ears. Genial !, but before going to the gym, take a bottle of hydrate yourself? Drink water while performing physical activity is very important.
The main purpose of the water is to avoid dehydration, but this is not enough during exercise: you also have to do this before and after. In this sense, if you start physical activity with some degree of dehydration, however minimal, its performance will be worse. In fact, it is likely to feel bad, your muscles will not respond well and can suffer cramps.
On the other hand, if you find yourself well hydrated will make more productive and longer sessions. Everything will be simpler, and your heart will not have to work as hard to pump blood, nutrients and oxygen can be more easily transported to the muscles of your body.
First of all, it's important to stay hydrated throughout the day. So try to have a glass of water always around. You have to drink between 450 and 600 milliliters of water, one or two hours before physical activity. Just before you begin, it needs between 200 and 300 milliliters. And during exercise, drink 200 ml every 15 minutes or so.
Whenever you exercise for less than an hour you will not need to resort to energy drinks. The water will be all you need.
