1. An exercise device comprising:
- a frame;
a first curved track having a first portion pivotally connected directly to the frame;
a second curved track having a first portion pivotally connected directly to the frame;
a track drive connected to a second portion of the first curved track and a second portion of the second curved track, the track drive configured to raise and lower the first curved track and the second curved track, alternately, provide vertically opposed motions;
a first footpad movably supported along the first curved track, wherein movement of the first foot pad is independent of movement of the first curved track; and
a second footpad movably supported along the second curved track, wherein forward and rearward movement of the second footpad is synchronized with rearward and forward movement, respectively, of the first footpad and wherein the first foot pad and the second foot pad are configured to change between a plurality of different available paths in response to force applied by a person to the first footpad and the second footpad;
a first swing arm pivotally coupled to the frame and pivotally connected to the first footpad; and
a second swing arm pivotally coupled to the frame and pivotally connected to the second footpad.

22. An exercise device comprising:
-
a frame; a first curved track having a first portion pivotally supported by the frame; a second curved track having a first portion pivotally supported by the frame; a track drive connected to a second portion of the first curved track and a second portion of the second curved track, the track drive configured to raise and lower the first track and the second track, alternately, provide vertically opposed motions, wherein the track drive comprises; a first pulley; one or more flexible members suspending a second portion of the first track and a second portion of the second track from the first pulley; a second pulley coupled to the first pulley so as to rotate with the first pulley; a third pulley rotationally supported by the frame; a belt wrapped about the second pulley and the third pulley; a flywheel rotationally supported by the frame; and a lever arm having a first portion eccentrically connected to the third pulley and a second portion eccentrically connected to the flywheel; a first footpad movably supported along the first track; and a second footpad movably supported along the second track, wherein forward rearward movement of the second footpad is synchronized with rearward and forward movement, respectively, of the first footpad. - View Dependent Claims (23)
