I'm 5'10 and 70kgs.
I go to the gym 4 times a week hitting a different muscle group each time. I am actively training in martial arts (very intensely) and average 1-3 hours training 6 days a week.
I drink around 2 gallons of water a day but I am constantly feeling thirsty...
Should I be worried or try to drink closer to 3 gallons instead?
