The core strengthening device includes a base having a first base section and a second base section. Each of the first and second base sections includes a connection mechanism with which to connect together to form a unitary device. The connection mechanism is detachable to separate the first and second base sections to form a two-part device. The device further includes a handle connected to a top surface of each of the first and second base sections. The device further includes two or more load-bearing rolling devices such as ball transfers or casters connected to a bottom surface of each of the first and second base sections to enable smooth movement over a surface by a user via the handles of the first and second base sections, either as the unitary device or independently as the two-part device. |
