So I have a hunchback from as long as I can remember. I don't know if it is rounded back or rounded shoulders. But when I try to do the wall slides my elbows touch the wall but the back of my hands cannot. So there is a wide angle between the wall and my arm. Is it because my back is too thick and rounded? I mean my upper back is quite far away from the back of my head. Ideally they should be more or less in the same line right? I also cannot keep my hands over a rod when I keep it at the back of my neck. My hands are always at the back of the rod.
