Abstract

The exercise device (10) exercises both the upper and lower body in associated motion, while preventing derailment or other related instability of the lower body linkage, due to the connection and force imparted from the upper body linkage. The device includes a frame (12) which has a forward upright member (20). The axle mounts (30) and (32) are attached to the rear region of the frame (12) and support a transverse axle (34) which is preferably operatively connected to a flywheel (36). The ends of the transverse axle (34) rotatably engage left and right crank arm assemblies (40) and (50) that are coupled to the left and right foot links (60) and (70) so that the foot links travel in an arcuate reciprocal path as the transverse axle rotates. The forward ends (62) and (72) of the foot links terminate in rollers (68) and (78), which engage guide tracks (42) and (52) that are mounted to the frame. The forward ends (62) and (72) of the foot links are operatively connected to safety engagement assemblies (100) and (110), which in turn are operatively connected to coupling regions (86) and (96) of swing arm mechanisms. The swing arm mechanisms are rotatably connected to the forward uprig…
