Hi guys I've got some mobility problems which are impacting my training at the
moment. Apparently the top of my thoracic spine is very mobile but the mid
back area (between my shoulder blades) is flattened and very inflexible,
according to my physio that happened due to overuse of my lower back erectors
which are now really strong as opposed to my mid back. Does anyone know any
mobility exercises that I could do for that area or anything that might help?
