<p>An oblong hoop formed of six tube pieces fitted together end to end has tube junctions at each of four beveled corners. A pair of telescoping side junctions preferably connects side tubes together to make the oblong hoop extendable and retractable in length. The hoop can be used in three ways during three stages of learning - first, with the pupil supported in the front region of the hoop and an instructor within the hoop and close behind the pupil, second, with the pupil remaining forward in the hoop and the instructor moving to a rear region of the hoop, and third, with the pupil remaining in the forward region of the hoop, and the instructor moving outside the hoop to hold onto a rear region of the hoop.</p> |
