The catch

The idea of the power jerk is too to jump aggressively to apply as much power possible to the bar, and then too very quickly reverse the athlete's upward motion downward so the bar is caught with the arms locked and the athlete is semi-squat position. There is no pressing motion per say in this movement but punch those arms hard to the sky.
