The ball will help you to gain your balance in this challenging posture.
Stand with the ball about 2 feet in front of you. Place your right palm against the top of the ball. Shift your body weight over your right foot. Exhale as you lift your left foot in toward your buttocks and grasp your left ankle with your left hand. Inhale as you reach back through your left leg, deepening the posture. Hold for 30 seconds, breathing normally, and then release and repeat on the other side.
