The worst I have ever seen is a guy who would sweat buckets while we would be doing techniques (Aikido) you couldnt even hold onto his wrist because it was so slippery or when he would pin you and you were on the ground you could feel the sweat run off of him and hit you in the back off the head. another was this kid who just went along with everything didnt put any restraint or any strength making alot of the moves difficult for some reason it just got frustrating because he was like a dead fish.
