Abstract
The present invention provides for a variable stride exercise device having a variable size close curved striding path during use. The exercise device described and depicted herein utilizes various configurations of linkage assemblies, cam members, and other components, connected with a frame to allow a user to dynamically vary his stride path during exercise. An exercise device conforming to aspects of the present invention provides a foot path that adapts to the change in stride length rather than forcing the user into a fixed size path. A user's exertion level may have several components impacting the stride length provided by the machine, such as leg power, torso power, and (in embodiments with arm supports or exercise components) arm power. Other embodiments of the exercise device include a lockout device that selectively eliminates the variable stride features of the exercise device and allows the user to exercise in a stepping motion.
