Just done Day 15 - Thoracic Mobility. This bridge feels quite comfortable and I struggle to feel a stretch, however when I look at the video, it doesn't seem as though I have much extension or arch in the Thoracic spine. What are your thoughts and how can I increase this? Btw, I am concentrating on really engaging the glutes, pushing shoulders away from my ears and rotating my chest up to the wall behind my head.
Really appreciate any guidance.
