Rotational exercise device

Abstract

A rotational-exercise-device (device) is disclosed. In some exemplary embodiments, the device may comprise: a handle-member and a rotational-member. The handle-member may be an elongate member. The handle-member may further comprise a first-handle-member and a second-handle-member. The first-handle-member may removably attach to the second-handle-member. The handle-member may include a longitudinal-axis which runs down a center-longitude of the handle-member. The rotational-member may be a substantially ovoid shape. The rotational-member may comprise a hollow cylindrical cavity passing through a longitude-center of the rotational-member. A portion of the handle-member may pass removably through the longitude-center of the rotational-member. The rotational-member may be configured to rotate about this portion. When assembled and in use, a user may grip each handle-member (or portion thereof) and perform various exercises by placing some of the user's weight upon the rotational-member, while the user causes the rotational-member to rotate against some surface, such as a floor and/or wall.
