An exercise device with advanced bench-cycling exercises for glute, abs and leg toning, for use in both the stomach down and up positions, has: a bottom support and at least one main support stem extending upwardly; a main joint body support frame rotatably connected to the support stem to allow lower support and upper support bars to be tiltable. The upper support bar is sufficient to support at least a portion of a human torso, and is rotatably connected to the main joint; one or two lower support bars adjustable in length, and having a top portion connected to the main joint, upper support bar or the at least one support stem; and a bottom portion extended away from the main joint; two cranks located on the bottom portion of the lower support bar; and a pair of pedals separately connected to their cranks, the cranks being adjustable in length.

A left leg unit includes a vertical piece; a horizontal piece; a vertical guide groove; a horizontal guide groove; an outer coupling bar to which the vertical piece and the horizontal piece are rotatably coupled, thereby coupling the vertical piece and the horizontal piece to each other; and a pedal that is rotatably coupled to the outer coupling bar. The vertical guide groove and the horizontal guide groove are extended in such a way that they intersect with each other. A rotation axis of the pedal is disposed away from a rotation axis of the vertical piece and a rotation axis of the horizontal piece and is disposed away from a midpoint of a line that connects the rotation axis of the vertical piece and the rotation axis of the horizontal piece, whereby the rotation axis of the pedal moves along an elliptical trajectory.

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 stationary indoor “smart” training bicycle includes a unique combination of adjustable components to provide configurable dimensions to adjust the frame size of the indoor bicycle to properly fit a rider. A system is also provided to process a digital image of an outdoor bicycle and determine and translate dimensions and adjustments to the indoor bicycle to match one or more dimensions (lengths, angles, separations, etc.) of the outdoor bicycle.

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 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.

A stride emulator device for efficiently utilizing human leg power for transference to a rotary drive system including a pair of levers, at least two gears, at least two crankshafts having crank arms, and where each lever includes a cam and cam track.

An exercising apparatus for exercising at least one limb, having a supporting frame and at least one crank which is arranged on a rotation shaft assigned to the supporting frame, and having at least one limb support which can be fastened to the at least one crank at different radial distances from the rotation shaft. A detector is provided for detecting the radial distance of the at least one limb support from the rotation shaft. The invention further relates to a limb support and to a method for determining the force acting on a limb support of an exercising apparatus.

Split-crank pedaling devices and methods of operation support patient use and rehabilitation, particularly for stroke patients. A split-crank pedaling device includes first and second crank assemblies. First and second motors are operably connected to the first and second crank assemblies. A first shaft sensor produces an indication of a position of the shaft of the first crank assembly. A second shaft sensor produces an indication of a position of the shaft of the second crank assembly. A controller is communicatively connected to the first and second motors and the first and second shaft sensors and calculates a phase error between the positions of the first and second shafts and a predetermined phase relationship between the first and second shafts. The controller operates at least one of the first motor or the second motor to provide a supplemental torque to one of the first crank assembly and the second crank assembly.

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.
