<p>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.</p> |
