A rolling exercise device with a low profile includes an elongated handle, a pair of separate support bodies, connections securing the support bodies at their facing inner sides to opposite ends of the handle so as to maintain the support bodies and the handle in a fixed relationship with respect to each other, mounting seats provided beneath each of the support bodies, and rollers rotatably mounted in the mounting seats so as to adapt the support bodies to be freely rolled by the rollers across a support surface as a user gripping the handle supports a portion of his or her weight on the handle. The device has a modular construction in the sense that the support bodies are interchangeable with one another with respect to their relationships to the opposite ends of the handle.
