Sit on your heels. Shift your left bun to the left, so that it is on the floor. Grab hold of your right ankle and place it to the left of your left knee. Straighten your left arm and place it across your chest, between your chest and your raised leg. Use that arm to push against your leg as you twist to the right. Twist as far as you can without hurting yourself, as you keep breathing deeply. Return to center and repeat on the other side: right bun to the right, left ankle over knee, right arm across chest, twist to the left, breathing.
