The disclosure relates to a cable tensioning station for providing a defined resistance force for resistance training, including a weight (9), which is arranged movably above a pull element (7, 17) and on which the resistance force is at least dependent, the pull element (7, 17) being guided via at least one coupling roller (18), which is designed to transfer a linear motion of the pull element as a rotary motion to a generator (19) to generate electrical energy, characterised in that the coupling roller (18) is embodied as a freewheel with adjustable blocking effect.

A monitoring device performs a method of detecting a need for maintenance of an exercise machine comprising a time-of-flight, ToF, sensor. The method comprises obtaining a measurement signal from the ToF sensor at a predefined operating condition of the exercise machine. Based on the measurement signal, the method determines a measured distance between the ToF sensor and a reflective element in the exercise machine. The measured distance has been found to be responsive to accumulation of deposits on the ToF sensor and is thus evaluated by the method to detect a need for cleaning. The method thereby enables preventive maintenance.

A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.

Assisted unracking of digital resistance includes detecting a state of a cable. A motor is mechanically coupled to the cable to provide resistance during an exercise by tensioning the cable. It further includes determining a readiness of the user to accept resistance based at least in part on the detected state of the cable. It further includes selectively applying resistance by the motor to the cable according to the determined readiness of the user to accept the resistance.

An exercise device includes a frame and a mirrored surface connected to the frame. A display is disposed within the frame and is positioned such that the display is viewable through at least a portion of the mirrored surface. The exercise device includes one or more arms rotatably attached to the frame and one or more arm motors configured to position the arms relative to the frame. One or more pull cables extend from the one or more arms, and a resistance mechanism including a motor is configured to resist movement of the pull cables.

A weight system having at least one weight stack moveable in a vertical direction on a lift rod, and a bearing block for housing a linear bearing. The invention further includes a method and apparatus for aligning the linear bearing.

A method for operating a motivation enhancing exercise system includes an exercise device configured to be driven by an exercising user, a head mounted output device configured to output a visual and/or an audible output for an exercising user, and a processing unit. Movements of a movable part of the exercise device are measured by means of a first sensor unit mounted on the movable part, and movements of a head of the user are measured by means of a second sensor unit comprised in the head mounted output device. The processing unit determines an activity being performed by the exercising user, and generates an output signal for the head mounted output device, in accordance with the determined activity. The head mounted output device provides a visual and/or audible output for the exercising user in accordance with the output signal.

A folding exercise rack system which may be both adjusted with respect to a wall and adjusted between a folded position for storage and an extended position for use. The folding exercise rack system generally includes an exercise rack that is both adjustable with respect to the wall and foldable between extended and retracted positions. The exercise rack generally includes a pair of inner support members which are adjustably connected to the wall, and a pair of outer support members which are adjustable between an extended position and a retracted (e.g., folded) position. In the extended position, the outer support members are distally spaced away from the inner support members and wall. In the retracted position, the outer support members are positioned adjacent to the wall.

A load sensor includes a bolt configured to support a pulley of a weight machine, and a strain gauge laminated onto an exterior surface of a shoulder section of the bolt.

A computing system for determining osteogenic loading from an exercise apparatus for performing an exercise is provided. The exercise apparatus includes a loading interface, a frame, a linear adjustment system interposing between and fixedly coupled to the loading interface and the frame, and a sensor coupled to the linear adjustment system. A position of the loading interface of the exercise apparatus is adjusted through a movement of the linear adjustment system at one or more intermediate positions of a plurality of functional positions of the loading interface. A force exerted by a subject on the loading interface at the position in the one or more intermediate positions is received. A measurement of the force exerted by the subject on the loading interface at the position in the one or more intermediate positions from the sensor is obtained. A corresponding osteogenic loading for the force exerted by the subject is determined.
