Did you know that when you raise one arm above your head, your upper thoracic vertebrae need to rotate and laterally flex?! When you raise both arms they need to extend. And when they can’t the soft tissues in the shoulder joint take the brunt of it. The upper thoracic spine is the part of our spine that is most prone to stiffness and congestion. Mobilising the upper thoracic vertebrae means we can raise our arms above our head with greater ease and less stress on the shoulder joints. It also takes a lot of pressure off our neck! This exercise is very simple and very effective. Try raising your arms above your head, notice how that feels… do the exercise, raise your arms again, and notice the difference. Your shoulders will be so much happier!
