An exercise device includes first and second crank arms configured to rotate 180 degrees out of phase with respect to one another about a first axis; a track; first and second foot links, first and second footpads carried by the first and second foot links between the first link portion and the second link portion and first and second front arms. Each of the first and second foot links has a first link portion that moves along the track while pivoting. Each of the first and second front arms has a first arm portion pivotally coupled to one of the foot links and a second arm portion pivotally coupled one of the crank arms. In one embodiment, a disc rotates in response to movement of the first foot link along the track, wherein a magnet facing the disc forms an eddy brake.

In an exercise system having a remote communication system adapted to communicate with an exercise device, a method for generating an exercise program includes receiving route information identifying a route traveled by an individual during a real world exercise session, receiving audio information identifying a musical selection listened to by the individual during the real world exercise session, using the route information and the audio information to generate an exercise program. The exercise program includes control signals that cause an exercise device to substantially simulate the topographical characteristics of the route traveled by the individual during the real world exercise session, and audio signals representative of the musical selection listened to by the individual during the real world exercise session so that the musical selection is presented during a performance of the exercise program.

A vertical stepping machine includes a frame, a crank wheel connected to the frame, a crank arm extending away from a rotational axis of the crank wheel, and a pedal beam connected to the crank arm. A linkage assembly is connected to the frame at a fixed frame location and to the pedal beam at a fixed pedal beam location. A first linkage member of the linkage assembly has a length that forces the pedal beam to travel along an elliptical path as the crank wheel rotates.

A vertical stepping machine includes a frame, a crank wheel connected to the frame, a crank wheel connected to the frame, a pedal beam having a first end and a second end, wherein the first end is in mechanical communication with the crank wheel, a pedal connected to the second end of the pedal beam, a linkage assembly connected to the frame and to the pedal beam, an arm support rotatably connected to the frame, an arm linkage connecting the arm support to the linkage assembly, and a rotary resistance mechanism positioned above the crank wheel when the vertical stepping machine is in an upright orientation. The pedal beam moves in an elliptical path when the crank wheel rotates and the elliptical path has a vertical major axis and a horizontal minor axis when the vertical stepping machine is in an upright position.

An elliptical trainer has a main frame having two opposite sides, each having a linking device, a stepping device and an interlocking device mounted thereon, wherein the interlocking device is provided to connect the linking device and the stepping device. A damping device is mounted on the main frame and operated with the two interlocking devices so as to promote exercise on the elliptical trainer. A longitudinal axis of an elliptical foot motion of each stepping device is adjusted due to a step force from an operator for changing a working stroke of the elliptical trainer.

An exercise device is provided with a frame, two pedals, two first swing arms, two second swing arms, a resistance device, two link rods, two cranks, two limiting rods, and two roller assemblies. Each first swing arm has two ends, in which one end pivotally connects to the frame, and the other connects to one of the two second swing arms. Each second swing arm has two ends, in which one end connects to one first swing arm, and the other connects to one pedal. The resistance device has an axle. Each crank includes two ends, one end connecting to the axle, and the other connecting to one link rod. Each link rods includes two ends, one end connecting to one crank, and the other connecting to an area of one second swing arm. Each roller assembly connects to one second swing arm, and can slide along one limiting rod.

An exercise apparatus may provide a novel linkage assembly suitable for linking circular motion to relatively more complex, generally elliptical motion. Left and right rocker links may be rotatably mounted on a frame rotatable about a first axis. Left and right cranks may be mounted on the frame rotatable about a second axis. Left and right force receiving members may be movably connected between respective rocker links and cranks in such a manner that the force receiving members move through variable paths of motion that may change as a function of user applied force.

An exercise apparatus comprises a frame, left and right foot link supporting left and right foot pads. The left and right foot pads synchronously move out of phase through an elliptical path having an adjustable step height. The apparatus may include left and right side arms pivotally connected to the left and right foot links and pivotally supported by the frame. Left and right cranks eccentrically support left and right crank guides. Left and right links each have a first end pivotably connected to left and right foot links and a second end operably coupled to the left and right crank guides, respectively. A movable adjustment member is connected to left and right flexible members operably coupled to the left and right foot links. Movement of the adjustable member adjusts an extent to which the left and right flexible members wrap about the respective left and right crank guides.

Provided is an elliptical machine, including: a left cantilever and a right cantilever hung at a rear end of a frame body; and a left guide arm and a right guide arm pivotally connected to the left cantilever and the right cantilever respectively, where a first matching structure is arranged at a first end of the cantilever, a second matching structure is arranged on the guide arm, and the first matching structure and the second matching structure are a set of a shaft and a bearing assembly capable of being pivotally matched with each other; and the first matching structure is detachably connected to the cantilever, such that the bearing assembly and a shaft core between the cantilever and the guide arm can be conveniently assembled when the cantilever is mounted.

Disclosed are an anti-static bearing assembly and an elliptical machine. The anti-static bearing assembly includes a bearing seat, a bearing mechanism, and a conductive part, where an accommodating slot hole is provided in one side of the bearing seat, the bearing mechanism includes a bearing inner ring and a bearing outer ring, the bearing outer ring is connected to the bearing seat, a guide hole is provided in the bearing seat, a placement slot is provided in the bearing seat, a first end of the conductive part is inserted into the guide hole and is in conductive contact with the bearing mechanism, and a second end of the conductive part is placed in the placement slot and at least partially protrudes from an outer circumferential side of the bearing seat, such that the second end of the conductive part can be in conductive contact with the armrest swing rod.
