"O'kay this clip is going to be double crunches so you are involving the upper and lower body. You are going to grab the ball with your feet once you get down on the mat, o'kay? Put your hands behind your head and now what you are going to do is extend the legs up at the same time you are crunching so it is going to be a double challenge. O'kay, hands behind the head and extend the legs up and then bring them back down. You still want to keep that orange and that grapefruit and keep that space between your chin and your chest so you are not putting too much stress on your neck. Exhale on the way up and bring it down nice and slow. Extend the legs up and then relax down and keep the arms nice and open. Provide just light support to the chin and the neck so you don't get a lot of tension. Bring your arms in just slightly but a lot of people bring their arms in too close and that definitely puts a lot of tension on the neck and shoulders."
