Dead Hangs are great for creating space in the shoulder joint. It targets the Lat muscle which is a powerful internal rotator of the humerus (arm bone). The relaxation of this muscle may allow the shoulder to sit in a more neutral position. By driving the buttbone down , we may also create more space between the segments of the spine for decompression. If unable to do this, you may find a lat pull down machine, load it up with more weight than you weigh, and just hold on and slowly sit down.
