Mark RippetoeThe hang clean is unweighted and is of little use to watch, except that it shows a problem known as a Donkey Kick. As the jump occurs, the heels come up in the back and then stomp back down into place. This is a terrible waste of time and energy, and contributes nothing to making the bar go up. Stop doing this immediately or I will have you killed.
