Here’s a way to get the that delicious back stretch of Adho Mukha Svanasana without having to bear your own weight. Your back muscles will release simply because they are supported in letting go.
You can do this pose over the back of a soft, stuffed chair or by padding a yoga chair with blankets. You drape your body over the blankets, with the top of the chair at the hip creases which tractions your legs away from your hips and spine. Bend your knees if that is more relaxing.
