A foot-operated exercising device comprises a frame having a longitudinally-extending frame bar terminating at its opposite ends in a pair of transversely-extending frame legs for supporting the frame bar on a horizontal surface, and a pair of foot pedals rotatably mounted on the frame bar about a horizontal, transversely-extending axis. The device further includes a pair of variable-length arms pivotably mounted to one of the frame legs about vertical axes to permit pivotting the arms to an operable position extending at a desired angular relationship axially behind the frame legs, or to a non-operable position in folded relationship with respect to the frame legs.
