STEPS : The body is parallel to the earth, and supported by straight arms and one knee. The other leg is extended off the earth and reaches back with active toes. The abdomen is pulled up toward the spine. The pelvis is tucked. The neck is a natural extension of the spine. The chin is slightly tucked. The palms are flat and the elbows are close to the side body. The joints are stacked with the wrists, elbows and shoulders in a straight line perpendicular to the earth. The gaze follows the spine and the eyes are focused down toward the earth.
