From Mountain (Tadasana), step the left foot back and turn it toward the edge of the mat at 90 degrees. The right foot faces forward. Intersect the arch of the back, left foot with the heel of the right. Press down through the pinkie edge side of the back foot and lift the inner arch. This will activate the inner leg line. Check to make sure the right knee is directly over the right ankle and in line with the 2nd and 3rd toe. Bend the front knee at a 90 degree, right angle. Eventually the thigh will become parallel to the mat. Hips face the side of the mat. Stack your shoulders directly over your hips. Extend the arms out to a T, palms facing down. Keep the arms active. Line up the back fingers behind the back shoulder. Gaze over the right fingertips. Lengthen your tailbone and keep your front ribs in.
