Drop the left arm down and bring it around and up so that the arm extends over the head and the left ear and bicep are approaching each other. Rotate the chest to the left and feel a long diagonal line from the outer edge of your back foot  through your left finger tips keeping the spine and back leg and top arm in one line. Relax your left shoulder away from your left ear. Keep a deep bend in the right knee forming a right angle so the knee is directly over the ankle. Send energy into the back leg so that you are not collapsing into the front leg. Keep the torso lifting and opening preventing it from resting on the front leg. There is so much going on physically in this pose it is important to remain focused and to breath deeply exploring the all of the mini movements and adjustments created by breath. This adds a deeper understanding of the pose.

Utthita Parsvakonasana also provides a nice stretch in the groin. The muscles of the torso are also working to rotate, extend and hold the pose .This helps to tone the waist and hips.
