ABSTRACT:
An exercise device having a two-sided support, a first double crank journaled in the support, the first double crank having an offset, outwardly extending axle on each side of the support and a second double crank journaled in the support, the second double crank having an offset, outwardly extending axle on each side of the support. A pedal is disposed on each side of the support for the user to stand on, the axle of the first crank supporting the pedal near one end, this axle adapted to move longitudinally relative to its respective pedal, and the axle of the second crank journaled near the opposite end of the pedal, the pedals operable in a cyclic manner to turn the first and second cranks. One of the cranks is rotationally advance relative to the other, and the cranks are connected by a timing belt so that they turn in unison. Handlebars may extend upwardly from each pedal.
