So I see guys that are swole up drinking something out of a milk jug the entire time they work out. Then on a Planet Fitness commercial where the big guy keeps saying "I pick things up and put them down" he's got a jug and drinking out of it. I've even seen MMA fighters drinking something like that during training.

What is it?
