9) Head Hang Backward, click here.
This stretch is the opposite of the Head Hang. It should also feel very easy if you have proper ROM through the cervical flexors. Much like the Head Hang, if you have trouble with this stretch you should seek professional hands-on assistance to get your best results. Place your hands on your chest and pull down while you lift your chin to better stretch the platysma muscle in the front of your neck.
