Lower the bar down to the knees, as if you were doing a Romanian deadlift.
Explode into a vertical jump while holding the bar. Do not pull the bar. The arms stay straight.
Don't lower the bar too slowly. Just keep it under control. Be sure to finish the hip extension; make yourself "tall." Don't be surprised if you jump backward a bit when you get it right.
Dave doesn't waste words. In fact, when he met his wife, he just pointed to what he wanted. Same thing with his articles. No build up. No smooth talking. He just gets right to the point.
