An exerciser includes a pair of levers and a pair of cranks pivotally secured on a base and a pair of beams secured between the levers and the cranks for allowing the beams to move along a circular path.

Two further cranks are secured to the cranks and are pivotally coupled to the foot supports by a pair of links for allowing the links to move the foot supports along the beams.
