A body weight support system includes a support track, a trolley, and a power rail. The support track has a first portion and a second portion. The trolley has a support assembly and a drive assembly. The support assembly is configured to support at least a portion of a body weight of a user. The drive assembly is configured to movably suspend the trolley from the first portion of the support track when the user moves along a first surface and is configured to movably suspend the trolley from the second portion of the support track when the user moves along a second surface separate from the first surface. The power rail is coupled to the support track and is configured to be in electrical contact with a portion of the trolley as the trolley moves along the first portion and the second portion of the support track.

An eddy current type resistance device comprising: a ring-shaped flywheel; a shaft center, the shaft center has an axial blind hole, the shaft center has a radial blind hole, the radial blind hole is connected to the axial blind hole; a positioning frame, connected to the shaft center inside the ring-shaped flywheel; multiple magnetic field generating components, evenly arranged on the positioning frame, and make the signal wires of the magnetic field generating components pass through the radial blind hole and the axial blind hole the outer end of the shaft center; and a side cover, connecting to the other side of the ring-shaped flywheel, and is connected to the shaft center by a bearing. Thereby having the effect of simplifying the type and process of the side cover.

An exercise bench includes a base, a slidable seat coupled to and slidable along the base, and a removable pad positionable on frame. When the removable pad is positioned on the frame, the removable pad prevents movement of the slidable seat along the base and provides a static bench surface configured to support a user during a strength training exercise.

An improved exercise machine has a stationary longitudinal monorail structure that extends between front and back end stationary exercise platforms, and an exercise platform mounted on a levitated carriage that is reciprocally movable along the monorail between the stationary platforms. Magnetic elements arranged on various opposing surfaces of the carriage and monorail generate magnetic forces that levitate and stabilize the carriage as it moves relative to the monorail thus substantially eliminating contact friction. Springs selectively attachable to the movable platform provide a resistance force for exercising. Pseudo-levitation and eddy brake elements on the carriage and monorail structure further stabilize the carriage and platform.

A pedaling exercise device includes a rotation mechanism configured to pivotally support a rotation shaft to allow rotation, a pair of cranks having first ends connected to both ends of the rotation shaft of the rotation mechanism, respectively, a pair of links having first ends rotatably connected to second ends of the cranks, respectively, and having second ends provided with wheels, respectively, a pair of pedal portions connected to the links along a longitudinal direction of the links, respectively, a rolling surface connected to a first end of the rotation mechanism on a user side, and a restriction portion configured to restrict separation of the wheels from the upper surface of the rolling surface in a case where the first end of the rotation mechanism is lifted such that the rotation mechanism is erected in a state where a second end of the rotation mechanism is grounded.

A reformer includes a base having a longitudinal direction, a carriage coupled to the base and moveable relative to the base in the longitudinal direction, and an actuator coupled to the carriage and the base such that the actuator is arranged to exert a force between the carriage and the base. The force moves the carriage relative to the base in the longitudinal direction or resists movement of the carriage relative to the base in the longitudinal direction.

An exercise apparatus includes a first cable, a first motor configured to apply a tension to the first cable, a pair of pulleys, and a terminal. The first cable extends from the first motor, past the pair of pulleys, and to the terminal, and the terminal constrains a distal end of the first cable from retracting toward the first motor away from the terminal such that at least a minimum length of the first cable is maintained between the first motor and the terminal. The exercise apparatus also includes a first connection point between the pair of pulleys, wherein the first connection point is configured to selectively redirect the cable between the pair of pulley such that the first connection point experiences a first force corresponding to double the tension.

An electromagnetically controlled wheel resistance adjusting device includes a motor, a magnetic tile, a potentiometer, a circuit board, a socket, a connecting rod and an output gear. The socket, the motor and the potentiometer are electrically connected to the circuit board, respectively. An external controller may, through the socket and the circuit board, provide power to the motor and control operation of the motor. The external controller may, through the socket and the circuit board, provide power for the potentiometer and receive an output voltage sent by the potentiometer. The motor drives the magnetic tile to move through the output gear and the connecting rod. The output voltage of the potentiometer varies with the rotation angle of the output gear. The external controller may drive the magnetic tile to rotate through the motor, and determine the moving angle of the magnetic tile through the output voltage of the potentiometer.

An exercise device with a redundant monitoring and control circuit integrated within or otherwise in communication with various components of the exercised device to detect and act on real or possible improper operation of the exercise device. A redundant controller may, based on a determination of a potentially out of specification operating condition of the exercise device, transmit one or more control signals to alter (e.g., reduce or remove) power to the motor of the exercise device. The redundant controller may provide a control signal to a motor power gating device to remove power transmitted to the motor from a power source and/or enable an inhibitor line of a motor controller to disconnect main power from the motor. Controlling the motor power gating device and the inhibitor line may ensure that power is removed from the motor even when a conflicting signal is being transmitted to the motor.
