From a sitting or standing position, stick out your lower lip as far as you can to form a pout (place a finger on your chin; the skin should feel wrinkly and puckered). Hold this contraction for one second. Then, with your lip still out, contract the muscles at the front of your neck to lower your chin to your chest as far as possible without rounding your upper back. Pause and hold for another second, then relax your lips and straighten your neck to return to the starting position. That’s one rep. Complete two sets of 20 reps each.
