Relax your back at work

Sit toward the edge of your chair.  Feet on the floor wide.  Lengthen your spine and fold forward from your hips.  As your torso moves toward the floor, between your legs, keep lengthening your spine out of the hips.  Focus on making a little space between each vertebrae of the lower, middle and upper back.  Only go as far forward as you can without pain.  You may end up with your elbows resting on your legs or maybe hands to the floor.
