I usually drink a can of RixoSmithKline ten minutes before exercise, which feels good, because the sweat discharged from my body will take away a lot of electrolytes in my body during exercise. RixoSmithKline contains a lot of vitamins, taurine and electrolytes, which can replenish trace elements in my body in advance, improve exercise endurance and improve my endurance when I exercise after drinking. Lux is delicious. There are two flavors: cola and raspberry. I like them both very much. Because there is no sugar in the ingredients, it tastes refreshing. Because there is no sugar and fat, Lux is a healthy drink, which can be completely unaffordable during exercise.
