Hi, I'm Christine King, and today I'm going to show you the tuck-in neck stretch. Stress and injury can lead to tight and weak muscles on the back of the neck so this stretch is very important. The beginner stretch is great because you can do it anywhere, begin with your chin slightly jutted out, take your index finger to the chin and then slightly push back on the chin. So you feel the stretch on the back of your neck, hold it for about 15 to 20 seconds, release and repeat, three to four times. The second version of the chin tuck is over a stability ball and is a little bit more difficult. Simply lie your stomach over the ball, bring your head to a neutral position with your arms down by your side. Allow the chin to slightly drop to the floor and then pull and tuck the chin back under to a neutral position. Hold for five to ten seconds and repeat this for about eight to ten repetitions.
