In response to physical connection of an exercise accessory with a portion of an exercise machine, an identifier of the portion of the exercise machine is received. A signal including the identifier of the portion of the exercise machine is transmitted.

A method includes receiving treatment data pertaining to a user capable of using a treatment device to perform a treatment plan and receiving activity data pertaining to the user while the user engages in at least one activity. The method also includes generating treatment information using the treatment data and the activity data and writing to an associated memory, for access by a healthcare professional, the treatment information. The method also includes modifying at least one aspect of the treatment plan in response to receiving, from the healthcare professional, treatment plan input including at least one modification to the at least one aspect of the treatment plan.

A motorized lifting rack that selectively lifts and lowers a barbell through linear actuators is provided. The powered lifting rack can engage a barbell at floor level. The linear actuators can also selectively raise and lower safety bars design to “spot” the barbell for a single user. The powered lifting rack is embodied in a system that includes a platform that the safety bars can nest in. The platform provides a plurality of actuating benches for a user of the barbell to utilize.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

A system for rehabilitation is disclosed. The system for rehabilitation includes one or more electronic devices comprising one or more memory devices storing instructions, one or more network interface cards, and one or more sensors, wherein the one or more electronic devices are coupled to a user. The system for rehabilitation further includes one or more processing devices operatively coupled to the one or more memory devices, the one or more network interface cards, and the one or more sensors. The one or more processing devices are configured to execute the instructions to receive information from the one or more sensors. The one or more processing devices are further configured to execute the instructions to transmit the information to a computing device controlling an electromechanical device, via the one or more network interface cards.

A method for controlling a training machine is provided. Data of the force applied to a reciprocation means of the training machine by a user with the reciprocation means being locked as the reference force in the forward direction is obtained, and the forward load opposed to the force in the forward direction applied by the user and the backward load opposed to the force in the backward direction applied by the user are determined. Also, a load more than the reference force is applied to the reciprocation means as a backward load opposed to force in the backward direction applied by the user when the user applies force to the reciprocation means in the backward direction of the reciprocation means. As such, a relatively large load can be applied to the user when the user contracts or stretches the muscles to work out.

A fitness training apparatus comprising a controller configured to communicate instructions to a load generator to apply a selectively adjustable load to at least one retractable line provided in or on a base, the retractable line having a free end region, the at least one retractable line being extendible from a retracted state to an extended state upon application of a force to the free end region, wherein the load applied to the at least one retractable line acts against the force applied to the free end region. The controller is configured to perform operations comprising setting a target speed band for the at least one retractable line, receiving a speed of the at least one retractable line, and responsive to comparing the speed to the target speed band, modifying the selectively adjustable load to the at least one retractable line to maintain the target speed band.
