Hi Esther, I'm just starting on the exercises in your book.
My main problem is thoracic pain, and I think my thoracic spine is probably overly curved due to scheuermann's disease. My lower back is rarely painful.
I have found that my thoracic spine gets very tired and sore doing the stretch sitting and wonder if I am doing something wrong (in the same way it gests sore while sitting or deskworking, in general), or should I persist?
Are there any additional considerations for me?
