Is there a name for this?  Preloaded barbell, held vertically, moving hand over hand up and down it. Saw a guy in the gym doing this:

He had a preloaded barbell, and was holding it vertically and moving hand over hand up, the way that kids would see who picks first in a baseball game.  He'd get to the top of the bar and then move back down it.

It looked incredibly strenuous, and he was pretty in-the-zone w/ headphones in so I didn't stop to ask him if it had a name.

Any ideas?
