1. An exercise device comprising:
a body, the body having a top, a bottom, a first end located at an edge of the body, a second end located at an opposite edge of the body, and first and second sides extending between the first and second ends;
a first wheel assembly comprising a first wheel, the first wheel assembly connected to the body proximate to the first end;
a second wheel assembly comprising a second wheel, the second wheel assembly connected to the body proximate to the second end;
a shaft having opposing first and second shaft ends eccentrically and rotationally coupled to the first and second wheels, respectively, wherein the shaft is rotationally locked to the first and second wheels, and wherein the shaft extends from the first wheel to the second wheel;
a first energy storage device, wherein the exercise device is configured for the first energy storage device to be loaded and unloaded by a moving of the first wheel,
wherein when the first wheel is rotated in relation to the body from a rest position, the first energy storage device is loaded and applies a resisting torque to the first wheel, and when the first wheel is moved or allowed to move back to the rest position, the first energy storage device applies a restoring torque to the first wheel to urge the first wheel toward the rest position.
