One of the issues being a modern human is that you end up living in the front of your shoulder capsule. If you spend any amount of time driving or working at a computer, chances are good that your shoulders have been resting in the fronts of the capsules to such an extent that your posterior shoulder capsules are extremely tight. This causes two problems. It makes it difficult to pull your shoulders to the backs of the sockets (achieve correct posture), and causes you to lose the capacity to generate effective rotation in your shoulders (achieve a full range of motion). This video just shows some simple mobilization techniques that help loosen bad tissue in your lats, traps, triceps and pecs so you can get back into those basic shapes that the shoulder makes pain free.
