Claim Text:
1. A compact portable leg exercise device, comprising: a base member positionable on a support surface; a top platform disposed above and generally parallel to a plane defined by the base member and configured to move generally axially relative to the base member, the top platform configured to receive a user's foot thereon during use of the leg exercise device; a resilient member interposed between the base member and top platform and extending about an axis of the device; and a frame assembly fixedly coupled to and interposed between the top platform and base member, the frame assembly being co-axial with the resilient member, the frame assembly configured to move between an extended configuration and a collapsed configuration to facilitate axial movement of the top platform relative to the base member while inhibiting twisting of the top platform about the axis, the frame assembly comprising a plurality of hinged sections where each hinged section is defined by a pair of members that fold onto each other and gradually contact each other when the frame assembly moves toward the collapsed configuration, thereby inhibiting noise generation by the frame assembly during use, wherein in the extended configuration the top platform is supported solely by the resilient member and the frame assembly, wherein during use a user presses the top platform with their foot to move the top platform generally axially toward the base member and against a force exerted by the resilient member on the top platform during said motion.
