Start Neutral and Relaxed

Chin to Chest
Drop your chin to your chest, but don't move your body. Hold for a few moments to feel the muscles let go of the tension.
Bring your head slowly back. Again, hold and feel the stretch. Keep your mouth closed. Breath through your nose. Relax the tension you feel in your throat.
Back to Center
Bring your head back to center
Head to Left Shoulder
Then drop your left ear to your left shoulder, without lifting the shoulder, as in the picture.
Head to Right Shoulder
Next, slowly move your head to the right, and hold on that side for a few moments.
Now, roll the head in a slow circle several times one way, then several times the other way. Do not move your shoulders. Keep the mouth closed, keep your eyes open when rolling to prevent dizziness, which may or not be a problem for some people. Breath through your nose.
Back to Center
Return your head to the neutral position.
