This stretch targets the muscle that shrugs your shoulders, the Levator Scapulae. It attaches to the top of your shoulder-blade, and to the sides of the uppermost bones of the neck. To stretch, first side-bend your head away from the side you want to stretch, and hold for a couple of breaths. Secure the arm on the stretching side behind your back to keep your shoulder down. Next, gently rotate and nod your head so that your nose is pointing into your armpit. Increase the stretch if desired by gently pulling your head farther into the stretch with your opposite hand. Hold for 30 seconds or until a release is felt.
