In this tutorial, Jessica Cassity from Prevention Magazine guides us through how to do the downward-facing dog yoga position. This is a great anti-aging yoga move that also strengthens bones. This is a great move for anyone that is just beginning to do yoga. To get into position, get on all fours on a yoga mat on a flat and hard surface. Curl your toes under, and bend up pushing your head down and raising your stomach into the air. Firm your shoulder blades against your back and keep your head between your arms. Do this for 10-15 seconds, then stretch back down into your legs. Do this often to help loosen the muscles and stretch out the body.
