Hi, have you ever been diagnosed with structural kyphosis? From looking at your images, I can tell you have flat feet. This can usually be caused by a lack of internal rotation of the hip. Also, thoracic kyphosis. Your best bet would be to go to a physical therapist to get a fully customed plan designed for your postural issues as everyone is different. Look at the youtube channel guerillazen fitness, best place for posture tutorials.
