Let the trail elbow prop your hands to the top
Porzak coaches that you should not consciously lift the hands to the top of the backswing. With the right elbow kept underneath the hands through the turn, the hands get propped up on their own from the elbow's structure. He rejects the common 'get your hands up' cue and says you turn your hands to the top instead, letting elbow position create the height.
