The rhomboids are the very thin muscles located in your upper back between the shoulder blades. Since the rhomboids connect the shoulder blade (or scapula) to the spinal column, the relatively small muscles are responsible for a heavy burden that includes pulling your shoulders back for correct posture. Weakness or tightness (or both) in the rhomboids not only causes bad posture, but also eventually leads to pain.
