An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

The apparatus provides an exercise device that is portable, versatile, and enables the user to match the resistance of the device with the normal physiologic length-tension relationship of skeletal muscle. The device adds resistance in the form of cartridges that are stackable to summate resistance and can connect to a variety of attachments for use with arms, legs, or trunk, i.e., handle, bar, loop, etc. Given the device’s portability, it can be used freestyle or mounted to various surfaces.

A fitness device includes a main body, a left wing extending outwardly from the main body in a first direction, and a right wing extending outwardly from the main body in a second direction opposite the first direction. A cable extends from the main body to each of the left wing and the right wing. The fitness device further includes a gearbox, a spool assembly connected to an input end of the gearbox, a brake assembly connected to an output end of the gearbox, and a pulley assembly.

A controllable tension force is provided on a first cable. The first cable has a terminal end wherein the terminal end is adapted to attach to an accessory. The first cable is coupled to a motor. The first cable and motor are part of a resistance unit. The resistance unit is coupled to a user support unit having a sliding seat.

A walking training system includes a treadmill, a center-of-gravity position detection unit that detects a center-of-gravity position of a trainee from a load received from a sole of the trainee on a belt of the treadmill, a posture detection unit that detects a posture of the trainee, a center-of-gravity position estimation unit that estimates the center-of-gravity position of the trainee from the detected posture of the trainee, a determination unit that determines whether a difference between the detected center-of-gravity position and the estimated center-of-gravity position exceeds a predetermined value, and a notification unit that sends, when the determination unit determines that the difference exceeds the predetermined value, a notification notifying that whether the difference exceeds the predetermined value.

An exercise assembly includes a treadmill that has a belt which can be walked upon. The belt has a braking mechanism and the braking mechanism inhibits the belt from being moved thereby presenting resistance to a user attempting to walk on the belt. A set of pull bars is coupled to and extends upwardly from the treadmill for simulating pulling a heavy object. A set of push bars is coupled to and extends upwardly from the treadmill to simulate pushing a heavy object. A spool is rotatably integrated into the treadmill and the spool is in mechanical communication with the braking mechanism such that the spool resists being rotated. A rope is wrapped around the spool and the rope resists being pulled on by the user when the user walks on the treadmill for simulating pulling a heavy object with the rope.

Sensor data is collected from a sensor monitoring a tension generating device of an exercise machine. The sensor data is analyzed to determine whether the sensor data is within a specification. In the event the sensor data is not within the specification, an error stop mode is entered for the tension generating device.

A multi-gym apparatus comprises a frame, the frame having an upright structure and a bar assembly mounted movably on the upright structure between selected positions on the upright members. The bar assembly includes an elongate bar and a bracket attached to the elongate bar, the bracket being shaped and dimensioned to abut against at least one side of the upright structure. The bracket receives a locking means which is movable between a first position in which the locking means is engaged with upright structure thereby locking the bar in a selected position relative to the upright structure and a second position in which the locking means is clear of the upright structure thereby providing for movement of the bar relative to the upright structure. The elongate bar includes two outer bar members, one to each side of the bracket extending at an angle that projects forward of the bracket and upright structure.

An exercise machine monitoring and instruction system for the movement of an element of an exercise machine by an exerciser and providing automated feedback to the exerciser to help improve the exercise in real-time. The exercise machine monitoring and instruction system generally includes an exercise machine having a movable element that moves between a first position and a second position in a reciprocating manner, a sensor that detects a real-time position of the movable element, a processor in communication with the sensor to receive the real-time position data from the sensor related to a position of the movable element and a feedback device in communication with the processor that provides real-time instructions to the exerciser on how to adjust their workout to achieve a desired result.

The described embodiments relate to systems, methods, and apparatuses for providing linear tension to multiple areas of a person to improve training and exercise. The tension can be applied by cables supplied from cable spools that are attached within a resistance assembly. The resistance assembly can be worn as a backpack during exercises, thereby providing a portable means through which tension can be provided to the body. The cables from the resistance assembly can be attached to appendages such as the wrists and legs of the person, and the tension provided by the cables can be adjustable. For instance, the tension can be made non-uniform across the body in order to improve the person's ability to maneuver in situations where there is an imbalance of force on the body.
