I was working with a teacher of the Alexander Technique earlier this week. The Alexander Technique more of an Un-Learning process than a teaching process. It focuses on letting go of old, unconscious patterns of movement.
We focused on leading movement with the Atlanto/Occipital Joint, as opposed to the top of the head. This cues you draws your head up and forward as opposed to down and back.

After hours of this practice, i went to train. My MN/PE2 is good, but my torso hadn't been reaching that full upright position similar to the video. However, with the mornings practice still fresh on my mind i decided to begin the straddle up leading from the A/O joint. My form was literally the best it has ever been! My torso was completely upright and my legs were pulling in further.
If you have been struggling with mn/pe2, try leading from the A/O Joint. It takes you on a more upward/diagonal direction, which, I believe, helped "pull" my torso more upright.
