Half Moon Pose (Ardha Chandrasana) invites you to tap into both the calm, balancing energy of the moon and the fiery force of the sun. The pose teaches coordination and can help you understand the interdependence of the actions in your body. Half Moon Pose can also help you develop strong legs and open hips.
Perform Extended Triangle Pose (Utthita Trikonasana) to the right side, with your left hand resting on the left hip. Inhale, bend your right knee, and slide your left foot about 6 to 12 inches forward along the floor. At the same time, reach your right hand forward, beyond the little-toe side of the right foot, at least 12 inches.
Exhale, press your right hand and right heel firmly into the floor, and straighten your right leg, simultaneously lifting the left leg parallel (or a little above parallel) to the floor. Extend actively through the left heel to keep the raised leg strong. Be careful not to lock (and so hyperextend) the standing knee: make sure the kneecap is aligned straight forward and isn’t turned inward.
Rotate your upper torso to the left, but keep the left hip moving slightly forward. Most beginners should keep the left hand on the left hip and the head in a neutral position, gazing forward.
Bear the body’s weight mostly on the standing leg. Press the lower hand lightly to the floor, using it to intelligently regulate your balance. Lift the inner ankle of the standing foot strongly upward, as if drawing energy from the floor into the standing groin. Press the sacrum and scapulas firmly against the back torso, and lengthen the coccyx toward the raised heel.
Stay in this position for 30 seconds to 1 minute. Then lower the raised leg to the floor with an exhalation, and return to Trikonasana. Then perform the pose to the left for the same length of time.
