Abstract: An exercise apparatus, system, or kit that includes separate components that can be used together during a workout. In one embodiment, the exercise kit includes a hub having a monolithic body portion and sleeve portions thereon. During use, only the sleeve portions contact the surface upon which the hub is located. The hub also has an annular groove formed therein and a bore formed therethrough. The kit also includes an elongated bar that is configured to interact with the hub in multiple positions to enable user to perform difference exercises. The different positions include: (1) a first exercise position wherein the elongated bar is positioned within the bore and portions of the elongated bar protrude from the first and second ends of the monolithic body portion; and (2) a second exercise position wherein the elongated bar is positioned within the annular groove.

Abstract: An exercise system or kit that includes separate components that can be used together during a workout. In one embodiment, the exercise system includes a cylindrical body, an elongated bar, and one or more resistance bands. The elongated bar may be a one-piece bar or a multi-piece bar. The cylindrical body extends along a longitudinal axis and has an annular groove formed into its outer surface that surrounds the longitudinal axis and a bore extending through the cylindrical body in the direction of the longitudinal axis. The dimensions of the bar, the groove, and the bore are such that the bar can be inserted into and through the bore and the bar can be positioned within the annular groove to achieve different types of exercise. Furthermore, the resistance bands can be coupled to the elongated bar.
