so do i neglect the upper body movement and just keep it locked, and use all my leg power, the bar will fly in place.
Yes. There is a saying in Olympic weightlifting that states “when the elbows bend, the power ends.” Basically, this means that all power should come from the legs and low back. In all but the best Oympic weightlifters the arms bend only in response to the bar flying upwards.
