Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

The present disclosure describes an exercise device including a first base and a second base. The first base includes a pair of support handles rotatably connected to the first base, a pair of cable arms rotatably connected to the first base, wherein the pair of cable arms include a first engagement mechanism, an electronic resistance device connected to a pair of cable handles via a pair of cables that pass through a pair of channels defined by the pair of cable arms; and a seat. The second base includes a beam affixed to and connecting the first base and the second base. The beam includes a track, a backrest carriage that is slidably engaged with the track and includes a second and third engagement mechanism, and a backrest rotatably connected to an end of the backrest carriage.

A weight training apparatus includes an electrical hoist and a cable coupled to the electrical hoist. A first end of the cable is coupled to the electrical hoist and a second end is configured to attach to a barbell assembly. A sensor is configured to output a signal indicative of a lift position of the barbell assembly. A controller is programmed to compare the lift position to an predetermined vertical locations and activate the electrical hoist to change the lift position of the barbell assembly based at least in part on at least one of the lift position or vertical lift velocity relative to the predetermined vertical locations.

An abdominal exercise roller with a powered wheel mechanism to assist the user during the abdominal exercise routine. The invention includes utilizing sensing technology and the electronic module to control the motor and optimize the performance of the abdominal roller during the exercise routine.

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 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.

In some embodiments, two or more different types of stator structures may be disposed within a gap of an axial flux machine. Such arrangements may be advantageous, for example, for producing a machine optimized for multiple modes of operation, such as mechanical torque generation, conversion of mechanical torque to electrical power, and/or dissipation of mechanical power. Further, in some embodiments, an axial flux machine may include a planar stator having a winding arranged to be positioned within the machine's active region, and may further include at least one switch configured to be selectively closed to establish an electrical connection between respective ends of the winding at a time that the winding is not coupled to an external power source.

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.
