An exerciser (10) includes a floor engaging frame (14) and a forward upright post structure (18). Towards the rear of the frame (14) are attached left and right axle mount supports (22) and (24) which house a transverse axle (26). The axle (26) is bifurcated allowing the two halves to rotate independently of one another and connect to left and right drive wheels (30) and (32) respectively. Left and right foot link members (36) and (38) rollably engage the drive wheels at the link member's rear end portions (48) and (50). The forward end portions (42) and (44) of the foot link members rollably engage left and right inclinable guide ramps (60) and (62). The inclinable guide ramps (60) and (62) are biased rotationally upwardly, to resist downward forces, by biasing members, such as springs (74). Left and right foot support portions (54) and (56) are mounted on the foot link members. As the foot link members reciprocate forwardly and rearwardly along the inclinable guide ramps, the interaction of the oscillating weight of a running or walking user, together with the independently upwardly biased inclinable guide ramps (60) and (62), causes the foot support portions to travel along an elliptical path.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [34.] An exercise device, comprising:a frame having a bifurcated transverse, staionary, rotatable axle defined thereon, the frame configured to be supported on a floor;a first and second foot link, each foot link including a first end portion a second end portion and a foot support portion;a bifurcated drive system, each half of which is independently operatively associated with a respective foot link by rollably engaging the second end portion of each foot link;first and second tiltable guide ramps pivotally supported by the frame for directing the first end portions of the foot links mutually independently along the length of the respective ramps, the first and second guide ramps cooperatively associated with the first end portions of said first and second foot links respectively, such that the inclination of the ramps are related to the positions of the first end portions of the foot links along the respective ramps; andwhereby as the first and second foot links travel forward and aft, the foot support portions of the foot links travel along elliptical paths.
