This is a very intensive neck stretch. The upper body is supposed to be on the wall, the chin too. With time one can move lower and lower with the arms. Not only the neck, but the entire upper back is challenged including the shoulders. Holding the pose for quite some time and breathing in a relaxed way supports the stretching activity.

The picture shows: There is a long way to go.

I don’t feel stuck anymore as I’ve learned so many new exercises that I can integrate in my daily practice.
