i was thinking the same thing, but then i was thinking that maybe after a long time of training at that time his body has gotten used to it and like "saved" all the energy till then lol (is this even possible) im thinking that its possible like when you try to sleep for 6 hours a night and your body is used to 8 hours eventually your body doesnt need 8 hours it only needs 8 so its not that bad then...im not even sure if this makes any sense lol
