The Cobra Pose is a chest-opening backbend that extends your entire upper body and can help if you have tension in your shoulders, lower back, upper back, or consistent pain around your arms. The upper torso (chest, shoulders, upper abdomen) and neck are pulled upwards in the final pose, resembling a serpent or snake (perhaps a Cobra). It falls within the category of "laying down on the stomach"; therefore, it's classified as a prone yoga pose.
