It is provided an apparatus for training a person's lower and/or upper extremities, comprising at least two motion elements which are arranged on a base element, wherein the motion elements each have an axis of rotation around which an actuating element can be moved. The motion elements each are independently movable relative to the base element about a first axis of movement, wherein the first axis of movement extends substantially perpendicular to an extension surface of the base element. Each motion element has a separate drive in order to rotate the actuating elements about the axis of rotation, and that the apparatus includes a control element which can individually actuate each drive in order to provide for a movement of each drive independent of a movement of another drive.

An indoor, stationary, bicycle training device that provides advantages over conventional designs of exercise bicycles is provided. The stationary bicycle may include a tilting/pivoting mechanism to orient the indoor bicycle to simulate descending or climbing. The indoor bicycle may include flexible and resilient frame elements to support the indoor training device to move side-to-side under some riding situations thereby simulating the side-to-side swaying motion of an outdoor bicycle under the same riding situations. The indoor bicycle may include several combinations of frame adjustments to provide configurable dimensions of the indoor bicycle to adjust the frame to properly fit the rider, which may be adjusted based on corresponding dimensions of a user's outdoor bicycle. Still other aspects of the stationary bicycle device may aid in creating an outdoor feeling while using the device.

A method is disclosed for using an artificial intelligence engine to interact with a user of an exercise device during an exercise session. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive data as input, and based on the data, providing an output. While a user performs an exercise using the exercise device, the method includes receiving the data from an input peripheral of a computing device associated with the user. Based on the data being received from the input peripheral, the method includes determining, via the machine learning model, the output to control an aspect of the exercise device.

A method is disclosed for using an artificial intelligence engine to modify resistance of one or more pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive one or more measurements as input, and outputting, based on the one or more measurements, a control instruction that causes the exercise device to modify the resistance of the one or more pedals. The method includes receiving the one or more measurements from a sensor associated with the one or more pedals of the exercise device, determining whether the one or more measurements satisfy a trigger condition, and responsive to determining that the one or more measurements satisfy the trigger condition, transmitting the control instruction to the exercise device.

A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.

Provided is an exercise device for performing exercises suitable to strengthen thigh and hip muscles such as a leg press machine, a total hip, a stationary bicycle, or a moving bicycle, and more particularly provides an exercise device for strengthening thigh and hip muscles while protecting the knees and ankle joints by enabling a user to locate a lower end of an arm on the user's thighs in a sitting, prone or supine position and move the user's legs in order to minimize a load or stress added to the knee and ankle joints.

A pulsatile resistive exerciser control system. The control system changes the resistance that a muscle feels in the millisecond time frame. The control systems comprising a stationary or elliptical bike having a drive belt secured to an electric alternator that is modified to allow for the modulation of the alternator output thereby allowing for the pulsation of resistance. The device can be set to exert a rapid increase in the resistance on the pedal at a specified point in the rotation of a stationary bike, or the gliding pedal of an elliptical bike, thus exerting a force on a specific muscle.

An adjustment device for exercise apparatuses which comprises a flange, a coupling body coupled to the flange by a pressure bar, an adjustment protrusion and a pressure pin, a coupling ring through which the coupling body is passed, a vertical arm connected to the coupling body so as to be adjusted in the back and forth direction and rotationally, and a coupling arm connected to the vertical arm.

In an exercise machine, foot platforms may travel in inclined circular paths to establish three dimensional operational characteristics. Platform support members may be rotationally synchronized by connected mechanical components such that they are maintained out of phase with each other by one half of a cycle or 180 degrees in counter rotational directions. Crank synchronization in an inclined plane during operation of the exercise machine may provide three-dimensional foot travel in vertical, lateral and longitudinal directions.
