Lay on your back with feet planted firmly on the ground. Place hands at the nape of your neck, and raise one shoulder blade off the ground, as if to reach your elbow to opposite knee. Lower gently and switch sides. The strength in this movement should come from your core, not from your hands pulling head forward (hands only job is to gently support the neck).
