Abstract: An exercising device for use by a child or an adult. This device includes a hollow plastic crossbar, and one or more hoops preferably hollow. Each hoop has an outer curved portion and two elongate straight portions with respective end portions. Each end portion has a fixed connection to the crossbar. The fixed connection is a pair of holes in the hollow crossbar, which receive a part of the straight portion with a press fit. The straight portion is adjustable relative to the crossbar by applying more than a preselected force thereon. The hoops are spaced apart at an equal angle spacing in a peripheral direction.
