Hi Leslie - yes the headrest was up intentionally, however, it can be changed according to preference. It should definitely be lowered for Short Spine.
Love the cueing, the tempo and your voice. Nice mentioning of the planes. However, I still think that there is too much elongation in your neck when doing the bridge with the headrest up.
Michal - having the headrest up was appropriate for the person in front of me. Likewise, you should adjust the headrest to suit your need or the needs of your client.
