Start with your hands, one on top of the other, behind your head, elbows wide and pinch your shoulder blades together to keep your back broad. Come up into your abdominals by drawing in your ribs.
Draw your right knee in and extend your left leg at a high diagonal. Turn your rib cage to the right by reaching your right elbow back. Reach your left ARMPIT to your right knee. Switch by drawing in your left knee and extending your right leg and reaching your left elbow back. Everything moves at the same time. Keep your shoulder blades off the mat. Add the breath as you switch sides. Keep your hips on the mat so you are not rocking back and forth.
