Methods and systems for controlling a force generator of an exercise apparatus are described wherein the method comprises determining or receiving angular positions of a rotatable axle of an exercise apparatus when a force is applied to a force receiving structure of the exercise apparatus, the rotatable axle being part of a mechanical power transmission system connecting the force receiving structure via the rotatable axis to a force generator which is controlled by a computer based on a kinematic model, the kinetic model representing equations of motion of the exercise the apparatus; determining or retrieving first geometrical scaling values associated with the angular positions and incorporating the first geometrical scaling values into the kinematic model to form a first modified kinematic model, the first geometrical scaling values being associated with a non- circular gear of a first predetermined non-circular geometry; and, determining applied force values for the angular positions, each applied force value representing a force that is applied to the force receiving structure; and, controlling the force generator based on first resistive force values to mimic an exercise apparatus comprising a mechanical power transmission system including the first non-circular gear, the first resistive force values being computed using the first modified kinematic model and the applied force values.

The present invention relates to an exercise method and an exercise device for performing an exercise suitable for thigh and hip muscles like fitness equipment or an exercise bicycle, and more particularly, to an exercise method and an exercise device for strengthening thigh and hip muscles by performing a movement of lowering legs and then moving the legs backward or putting the legs together or apart from a position of pulling the legs toward a chest of the user with an arm disposed between the legs in a sitting or lying position of the user. In addition, the present invention relates to a leg exercise device including a trajectory measuring device of generating motion range information of the exercise device and making the motion range information as data through a motion range measurement sensor attached to a knee and a hip joint of the user seated on the exercise device, smart device and an application of the smart device.

A resistance mechanism for an exercising device is provided. In one embodiment, the resistance mechanism comprises at least one flywheel. The resistance mechanism may also comprise at least one resistance index wedge configured to engage with the at least one flywheel. The resistance mechanism may also comprise a resistance adjustment mechanism connected to the resistance index wedge and configured to alter a resistance provided to the exercise device by increasing pressure provided by the at least one resistance index wedge to the at least one fly wheel assembly, wherein the resistance mechanism is configured to operate in an outdoor environment.

An exercise machine creates a simulated continuous resisted climbing motion. The machine includes a floor- or ground-contacting base frame and two or more substantially vertically oriented uprights, wherein at least one upright is rigidly connected to the base frame. The machine further includes two handles and two foot pedals, each handle and each foot pedal being movably engaged with an upright for linear reciprocating motion along the upright. The handles and foot pedals are interconnected so that they move concurrently. An adjustable resistance mechanism may be operatively connected to the interconnection of the handles and foot pedals to provide adjustable resistance for the simulated continuous climbing motion.

A bicycle training system and methods of using the same. The system includes a movement platform that rests on a support surface and supports a bicycle in an upright manner with respect to the support surface. The movement platform includes a support frame having a base and at least one upstanding arm that supportably engages a portion of a frame of the bicycle, a resistance assembly operatively coupled to a portion of a drivetrain of the bicycle that applies varying levels of resistance to the portion of the drivetrain, and a plurality of bushings isolating the base from the support surface. The plurality of bushings are spherical thereby permitting the movement platform to move with respect to the support surface in response to forces applied to the bicycle frame during use of the bicycle training system.

A stair exerciser apparatus includes a frame having a pair of inclined supports, a drive mechanism, and a plurality of stairs coupled to the drive mechanism for traveling around the pair of inclined supports. The driving mechanism has an upper shaft, a lower shaft and at least one drive chain mounted around the upper shaft and the lower shaft. A clutch mechanism is coupled to the upper shaft or the lower shaft of the drive mechanism. A flywheel is operationally coupled to the clutch mechanism, where the clutch mechanism couples the motion of the stairs to the rotation of the flywheel when the stairs are driven in a downward direction, and where the clutch mechanism decouples the motion of the stairs from the rotation of the flywheel when the stairs cease to be driven in the downward direction.

Exercise apparatuses are described. An example exercise apparatus has a lengthwise axis and includes a first shaft, a first frame, a first handle, a second frame, and a second handle. The first shaft has a first shaft first end and a first shaft second end. The first frame is attached to the first shaft first end and defines a first frame passageway. The first handle is disposed within the first frame passageway such that the first handle can translate along the lengthwise axis and rotate within the first frame passageway. The second frame is attached to the first shaft second end and defines a second frame passageway. The second handle is disposed within the second frame passageway such that the second handle can translate along the lengthwise axis and rotate within the second frame passageway.

Full body exercise equipment including four elongate rails arranged in a generally side-by-side longitudinal configuration. The four elongate rails are connected together to allow for selected angular arrangements between the rails and also allow for selected longitudinal arrangements between the rails. A slidable shuttle member is provided on each rail with the two inside rails having toe holds and the two outside rails having hand grips. A resilient cord is provided for each shuttle for selectable attachment to either end of the shuttle to provide selected resistance against slidable movement of the shuttle in either direction on a respective rail.
