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. A pair of foot supports are slidably engaged on the beams and are moved along the beams for allowing the foot supports to move along an elliptic 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.
