Caution: If you have neck problems or an injury, keep your neck in the original position in line with your torso instead of moving it with your spine. If you feel any pain when you do this pose, stop. Talk to a yoga instructor about how to adjust the pose. Or ask him or her to teach you a different pose that doesn't cause pain.

Start out on your hands and knees on a mat or carpet with your body aligned so that your shoulders are directly above your wrists and your hips are in line with your knees. Your back should be flat, and your neck should extend out straight from your spine. Your gaze should be toward the floor below.
