Begin in Mountain pose with feet together and hands on your hips, in prayer position or extended overhead. Step left foot back about 4–5 feet apart. Turn your left foot in about 45 degrees; your right heel should align with the arch of your left foot. Slowly bend the right knee until the thigh is parallel to the floor; keep the right knee either behind or directly over your ankle; be very strong and active in your left leg as you bend your right leg. Tuck your tailbone as you rotate your pelvis back. Inhale (bring hands to prayer position or extend overhead; allow face to follow hands). Hold this position and breathe evenly and comfortably through the nose. To come out of this pose, push into the floor with your left foot as you unbend your right leg. Repeat on the other side.
