The squat is much better. Look at the difference between the first rep and the last four. First is wrong, last four are good. Burn this into your little minds.
The 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.
