Abstract
A reciprocator for use with a stepper-type exercise machine has a channel as a rocker element. The channel has left and right ends which rotate about a pivot axis below the pedals. Rollers are mounted at each end of the channel. The rollers have a groove to engage with arcuate roller engagement structures attached to the underside of each pedal. The rollers are each mounted on a mount bar which spans the opening of the channel at the left and right ends. A pair of springs are positioned at each end to urge the roller away from the sides of the channel.
