Sitting with your back straight and shoulders down, tilt your head back so that you are looking at the ceiling. Close your lips so they are together but relaxed. Keeping your lips closed, open your mouth so it forms an “O” shape. Hold this position for 20 seconds. You should feel a contraction on both sides of your neck directly under your jaw line. Relax your mouth and lower your chin to return to the starting point. That’s one rep. Complete two sets of 10 reps each.
