After training juice spritzer? For Sure! Non-alcoholic beers? Of Course! ... The first half liter is with me but after prolonged or strenuous units for over a year Ultrasport. Immediately after training, even before showering in and well. Apple juice and beer can after eating always relaxed or drink.
On cold days, like, so that the body does not cool down even more with warm tap water.
Whether it works? Well :-) It tastes and has a lot of content, we can use athletes definitely good.
