This posture uses the hook hand called cranes beak. Form this hand gesture by touching all four fingers to the thumb and bending the wrist until the fingers point straight down.

1. Sink your weight to the rear leg letting your fingers remain in place. This means that the arms stretch a bit and straighten.
2. Lift your right toe and turn your waist to the left until you face northwest. Let this waist turn pull your arms and right foot with it. Both arms are straight at shoulder height and face northwest.
3. Sink the weight back to the right leg (Northeast) and draw the right elbow in to the waist. The right arm forms a cranes beak. Your left arm rotates down and in, ending resting on the right hip with the palm facing up.
4. Turn left to face northwest. Rotate on the left toes and extend the right hook arm to the Northeast. The right arm is slightly bent and level with your shoulders.
5. Sink on the right leg and step to the Southwest touching the heel down first. Step forward and outward to ensure you will have adequate width in the resulting forward stance. 
6. Roll your weight onto the left leg and let that sinking action rotate your left arm at the elbow until your fingers point straight up. The left palm faces toward you. Once your weight is securely on the left leg lift the toes of your right foot and turn your waist to the left (toe in). This action pulls your waist and your right foot into a right forward stance facing west. Your left arm rotates until the palm faces out. You now face west.
7. Sink and expand the body.
