It gets hot outside occasionally. What's your go-to drink between rounds? Just water, or an energy drink?
all your hydration should be handled the day before. the older you are 2 days before. just normal sips of only water during competition.
Proper hydration, take your body weight, divide it in half & drink that amount of water every day, not just before a shoot especially if you're over 60 180 lbs--90 oz of water
