I never linked calories with water intake but I could see the relationship. I always tried to follow the the piss clear idea. Now after a morning multi vit/min, 45 min. of cardio and during a mid cycle of Tren... No one is pissing clear. lol
Assuming your training takes 2 hr., you can down a gallon of water in that time?
Slightly off topic but man, with all that heat and all the water displacement in your guts, how the hell do you eat?
