The supine morning stretch is a great stretch for improving length throughout the body. It can help reduce pressure on the spinal bones and improve postural alignment.
Begin lying on your back with legs straight and arms down by your sides.
Reach both arms up overhead. Lengthen both legs away from you, reaching with the heels while pulling your toes up towards you. Stretch as if you are trying to elongate your body, reaching your hands and feet away from each other. Hold for 5 seconds. Relax.
