From Twisting Lizard, lie on your belly and extend your arms out in front of you.
Keeping your legs and pelvis grounded, slowly begin to walk your hands toward your chest. As your torso lifts off the floor, keep a slight bend in your elbows.
Walk your hands in until you feel a nice stretch in your abs. Relax your shoulders away from your ears and lengthen your neck. If it feels OK, lower your head back between your shoulder blades, and you'll feel a nice stretch in your chest and neck.
