Start to open your shoulders and hamstrings in this variation of Uttanasana (Standing Forward Bend). Stand in Tadasana (Mountain Pose) with your hands on your hips. Inhale and extend the spine. Exhale and hinge from your hips forward, moving from your hips, not from your back. As in all forward bends, emphasize the lengthening the both sides of your torso as you fold deeper. Bend your knees slightly and thread your right arm under your right thigh, internally rotating your right shoulder to bring your left arm behind your back. Clasp left arm with your right hand by your right hip if possible. Otherwise just place your hands wherever they land and open your chest to the left as you try to straighten your legs and straighten your left arm (if clasped.) Continue to press the heels and the balls of your feet firmly into the floor and lift the sitting bones toward the ceiling to accentuate the stretch. Take 5 breaths here before exhaling to release the arms, inhaling to rise, and switching sides.
