Try using a strap to connect your hands behind your back. Hold the strap in your right hand as you reach up, dropping the strap end down your back. Rotate your left shoulder forward and reach up your back with your left hand to grasp the strap; now, roll the top of the left shoulder back. Your feet can be touching or slightly wider than your hips. Just as in the full form, pull your hands in opposite directions. Sit tall and straight through the torso, neck, and head as you breathe smoothly.
