Abstract: An exercise device comprises a pair of wheels on opposite ends of an axle, and a pair of foot-receiving stirrups on the axle between the wheels. A user positions his or her feet in the stirrups, assumes a basic push-up position on a support surface and exercises either by walking along the surface on the hands, rolling the feet behind, or by maintaining the hands in stationary position and using the body to roll the wheels toward and away from the hands.
