Stand tall in fourth position (from first position take one step forward with your left foot, keeping it turned out, and cross it in front of your right) with your right hand resting on the back of the chair, left arm in second position. Rise up onto the balls of your feet, and then plié bending both knees out to the sides. Extend your right leg straight (keeping heel lifted), as you lift your left knee out to the side and lightly touch your left (pointed) toes just outside your right knee. Bring your left arm overhead into third position.
Lower your left foot back into fourth position and return your arm to second position (heels should remain lifted for the entire set). Repeat 20 times total with the left leg, 20 times with the right.
