ABSTRACT:
An exerciser (10) includes a floor engaging frame (14), towards the rear of which are attached left and right axle mount supports (22) and (24), that house a transverse axle (26). The axle (26) connects the left and right drive wheels (30) and (32). Rear portions of left and right foot link members (36) and (38) rollably engage the drive wheels. Front portions of the foot link members rollably engage left and right inclinable guide ramps (60) and (62). The inclinable guide ramps are biased rotationally upwardly, by a ramp return assembly (70) that causes one ramp to pivot downwardly as the other ramp pivots upwardly. Forward and rearward pulley and belt systems (72) and (76) are connected to the foot links and provide flexibly coordinated motion which substantially relates the movement of the first and second foot links to each other, while permitting some degree of uncoordinated motion between the foot links. When the foot link members reciprocate along the inclinable guide ramps, the interaction between the oscillating weight of a user and the upwardly biased guide ramps, causes the foot support portions to travel along elliptical paths.
