One item that I would consider adding to this toolkit is Feldenkrais practice. It has a reputation as a gentle and highly personal method for retraining deeply engrained bodily habits. There are practitioners all over the world who can do one-on-one hands on therapy, or you can look for recordings of guided practices.

A quick google search found this lesson [1] and I'm sure there are plenty of others.
