An elliptical stepper includes a base, a damping device mounted on the base, two crank devices respectively laterally mounted to two opposite sides of the damping device. Each crank device has a stepping device mounted thereon and each stepping device has a roller set mounted to a bottom thereof, wherein the roller set is universally rolled relative to a corresponding one of the two stepping device. The base includes two opposite sides each having a guiding structure disposed thereon. Each guiding structure includes at least one rail having a front end outwardly extending relative to a center line of the base. Each roller set is moved along a corresponding one of the two guiding structures such that each stepping device provides a wiggling effect when moved along an elliptical route.

An exercise apparatus having a pulley, a pair of stabilizing assemblies each configured to couple a front portion of a respective pedal element to each side of the pulley, a looped belt configured to couple the pulley to a resistance assembly, a tension stabilizer configured to maintain a tension of the looped belt on the pulley, and the resistance assembly configured to assert an adjustable resistance to the pedal elements through the looped belt, where the resistance is adjusted by changing a distance between a flywheel element and a corresponding magnetic plate element of the resistance assembly, the magnetic plate asserting a magnetic force over the distance on the flywheel element and the looped belt looping around a co-rotating extension from the flywheel element.

An exercise device for performing a variety of movement patterns. The exercise device has a pair of linkages, each including an upper link pivotally mounted to a frame and a lower link pivotally coupled to an upper link. A foot support is provided on a distal end of each lower link. A transfer system is coupled to the frame and both upper links for transferring both tensile and compressive forces. Separate torque elements are operably coupled to the frame and each lower link via a transfer member for independently resisting movement of the associated lower link.

An exercise device for performing a variety of movement patterns is provided, having an upper link pivotally mounted to a lower leg link and a foot support on a distal end of the lower leg link. A first transfer system is movably coupled to a frame and including a first transfer member coupled to the first upper leg link and a second transfer member coupled to the second upper leg link, thereby enabling substantially reciprocating motion of the first leg link relative to the second leg link. A second transfer system is also provided and may be movably coupled to the frame and including a pair of third transfer members coupled to each of a pair of fourth transfer members by way of each of a pair of transfer couplings, each movably mounted to the frame. The fourth transfer members may be coupled to the first lower leg link and the second lower leg link, whereby movement of the first lower leg link causes movement of the second lower leg link irrespective of movement of the upper leg links thereby providing a stable platform for the user and also enabling an infinite number of gait patters by the user.

An apparatus including a frame; a drive wheel coupled to the frame; first and second foot links operably coupled to said drive wheel to transfer power to said drive wheel so as to propel the apparatus; and each of said first and second foot links including a pivoting foot platform for receiving an operator's foot, said pivoting foot platform pivotally coupled to one of said first and second foot links so as to allow angular travel of the pivoting foot platform, the apparatus including one or more features to limit the angular travel of said pivoting foot platform.

An exercise device featuring a pair of knee joints, each pivotally coupled to a pair of calf linkages having foot pedals at their opposite lower end that support low impact user-defined natural exercise gait patterns. The knee pivots joints are supported and directed to travel by linkage and/or carriage systems that operate substantially below the user hip area, and direct the knee pivot joints in a variety of travel paths, ranging from having a constant arc, linear pathway, to having a variety of irregular arc shaped paths, as well as, pathways that may change during use. A secondary system coupled to the knee pivot support system, provides lift and dampening forces to influence the responsiveness of the foot pedals via the bending and straightening of the calf linkage about the knee pivot joint, yet do not restrict the back and forth travel of the knee joint.

Embodiments of an exercise machine are disclosed. In one embodiment, an exercise machine includes a base supporting frame, a handlebar assembly, a seating assembly, and a stepper assembly. The base supporting frame having a front end and a rear end is adapted to be positioned on a support surface. The handlebar assembly is positioned at the front end of the base supporting frame and is adapted for the user to hold onto while the user is standing on the pedals. The seating assembly is positioned at the rear end of the base supporting frame and is adapted for a user of the exercise machine to sit on the seating assembly while the user's feet are placed on the pedals. The stepper assembly is positioned between the seating assembly and the handlebar assembly and includes a pair of first and second reciprocating pedals rotatably mounted on the stepper assembly.

An exercise machine includes a joint assembly. The joint assembly includes a pivot rod, a first component connected to the pivot rod, a second component connected to the pivot rod, and a bushing mounted on the pivot rod between the first component and the second component. The bushing includes a body with a first side and a second side, the body comprising an elastic, flexible material; a first plate connected to the first side of the body; and a second plate connected to the second side of the body.

An exercise device including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.
