[0013] In certain embodiments, a variable stride system may be coupled to the pivotal linkage assembly. In some embodiments, a variable stride system may include a cam device. In certain embodiments, a variable stride system may include a spring device and/or a damper device. A variable stride system may be coupled to a foot member and/or a movable member. In certain embodimen...
Problems solved by technology
The fixed elliptical path length may either be too long for shorter users or too short for taller users.
Mechanisms for adjustment in such apparatus may add significant cost, may require input by a user to a control system, and/or may not react relatively quickly to user input.
Such increases in stride length, however, are generally a small percentage of stride length and are not generally perc...

Embodiment Construction
[0063] In the context of this patent, the term “coupled” means either a direct connection or an indirect connection (e.g., one or more intervening connections) between one or more objects or components. The phrase “directly attached” means a direct connection between objects or components.
[0064] Aerobic exercise apparatus may be designed to create a variable path (e.g., a closed path or a reciprocating path) in space for limb engaging devices. For example, an exercise apparatus may create an approximately elliptical or approximately circular closed path in space (e.g., as shown in FIGS. 1A and 1B) for foot pedals or footpads to simulate a climbing, walking, striding, or jogging motion. In some embodiments, an exercise apparatus may create an approximately curvilinear path in space (e.g., as shown in FIG. 1C) for foot pedals or footpads to simulate a walking, striding, or jogging motion. Footpads may move in a repetitive manner along a closed path. A closed path may be defined as a ...

Abstract
A variable stride exercise apparatus is described. A variable stride exercise apparatus may include a frame. A crank system may be coupled to the frame. A foot member may be coupled to the crank system. The foot member may include a footpad. A variable stride system may be coupled to the foot member. The variable stride system and the foot member may be coupled such that at least a portion of the variable stride system is under at least a portion of the footpad. The variable stride system may allow a user of the apparatus to vary the length of the user's stride during use of the apparatus. The foot of the user may travel in a substantially closed path during use of the apparatus. At least a portion of the apparatus may remain substantially stationary during use.
