Downward facing dog is a popular posture done in yoga. Often used in sun salutations, it decompresses the spine, strengthens the legs, as well as many other benefits. Begin by coming to the back of your mat, and actually, it's nice to start downward facing dog in table. So, if you come into table, you have your hands right underneath your shoulders; check for that, your knees right underneath your hips; check for that, a nice straight back, and then you lift up your toes. And then, putting a lot of the weight onto the finger pads, straightening the legs, bring the torso so that it's in between the hands, and lifting the sitting bones up. Draw the shoulder blades back; bring the heels as far back as you can. You can walk your dog by lifting your heel up one at a time. So, we're decompressing the spine here; we're allowing blood to flow, helping the lymphatic system along, strengthening the legs. Firm your quadriceps; breathe, breathe, and breathe, and breathe. Engage your abs.
