Looks bad ass, especially the part where you drop the bar after your last set.
The cool thing about a power clean is that you either use enough force to be able to rack the bar, or you don't rack the bar. This thing removes that pesky racking deal, so how do you know if you "completed" it? It's kinda like a cool-looking barbell shrug, but you can't use as much weight as you can with a shrug. How did you like them when you used them? What did you use them for?
