A pedal system for tracking use of a cycle style exercise device. The pedal system includes a pedal with a shaft for coupling to the pedal crank of the exercise device and a housing that is rotatable about the shaft. An accelerometer positioned in the housing is configured to provide data about the movement of the pedal to a microcontroller. A wireless communication chip positioned in the housing is used to transmit the data about the movement of the pedal to a remote device via the wireless communication chip. The remote device is programmed to receive, display and track the data about the movement of the pedal.

A system and method for a mixed or virtual reality-enhanced stationary exercise bicycle, comprising a stationary bicycle device, a belt-like attachment, and a mechanical arm attachment attached to the base of a stationary bike, used for measuring and determining user position for virtual or mixed reality-enhanced software.

A system includes a treatment apparatus configured to implement a treatment plan for rehabilitation to be performed by a user and a processing device configured to receive attribute data associated with the user; generate, based on the rehabilitation, selected attribute data; determine, based on the selected attribute data, the rehabilitation, and a rehabilitation goal associated with the rehabilitation, one or more probabilities of attaining the rehabilitation goal within respective one or more numbers of rehabilitation sessions to be performed by the user using the treatment apparatus; provide, based on the one or more probabilities, an indication of the one or more numbers of rehabilitation sessions; and generate, based on a selected number of rehabilitation sessions from among the one or more numbers of rehabilitation sessions, the treatment plan. The treatment plan includes one or more exercises directed to attaining the rehabilitation goal within the selected number of rehabilitation sessions.

An exercise machine has a crankshaft having a crankshaft mounting surface, a landing surface, and a crankshaft bore, a crank arm having a threaded crank arm bore and a crank arm mounting surface that is frictionally engaged with the crankshaft mounting surface, and a fastener that axially extends through the threaded crank arm bore and into engagement with the crankshaft bore to fasten the crank arm to the crankshaft. The threaded crank arm bore is configured for threaded engagement by a removal tool such that removal of the fastener and insertion and rotation of the removal tool in the threaded crank arm bore causes the removal tool to disengage the crank arm mounting surface from the crankshaft mounting surface and thus facilitates removal of the crank arm from the crankshaft. Methods of disassembling an exercise machine having a crank arm are also provided.

An exercise machine may include a frame with set of foot pedals mounted thereon. A seat-receiving space is defined by the frame rearward of the set of pedals and a seat that is in the form of an inflatable bladder is received within the seat-receiving space. The inflatable bladder is retained within the frame in such a way that the bladder is able to move within the frame when the exercise machine is used. A seat back extends upwardly of and adjacent the inflatable seat and supports a user's back while the user is seated on the inflatable seat. Left and right arms are secured to the frame and extend respectively to the left and right of the inflatable seat. The user may undertake a cardiovascular workout and a core workout of abdominal and back muscles using the exercise machine.

In a first aspect, a method is provided that includes the steps of (1) providing a monitor for determining a level of exercise performance performed by an exerciser and for outputting a signal representative of the performance level; (2) using the monitor to measure a level of exercise performance performed by an exerciser; (3) outputting from the monitor a signal representative of the performance level; (4) providing a video game having a character, the video game inputting and being responsive to the performance level signal output by the monitor, the video game using the performance level signal to control a performance level of the video game character; and (5) while the exerciser is not exercising, controlling a performance level of the video game character based on a performance level signal output by the monitor.

A method includes measuring, continually or iteratively, positions of an exercise apparatus along a circuit, wherein the exercise apparatus is configured for cyclic movement along the circuit. A plurality of muscles of a user coupled to the exercise apparatus can be stimulated based on the position of the exercise apparatus. The exercise apparatus can be a cycling device or a rowing machine.

A computer-implemented system may include a rowing machine, an interface comprising a display configured to present information pertaining to the treatment plan, and at least one processing device configured to receive, from sensors, measurements associated with the user, wherein the measurements are received while the user performs the treatment plan; determine, via machine learning models, content items to present to the user, wherein the determining is based on the measurements and one or more characteristics of the user; and while the user performs the treatment plan using the rowing machine, cause presentation of the content items on the interface, wherein the content items comprise at least information related to a state of the user, and the state of the user is associated with the measurements, the characteristics, or some combination thereof.

An exercise machine configured for a user to perform an exercise motion. A first frame is configured to be positioned on a floor. A second frame is supported by the first frame, the second frame being manually moveable by the user relative to the first frame into a desired position for the user to perform the exercise motion. A sensor detects an actual position of the second frame relative to the first frame. A display device is configured to display the actual position detected by the sensor to assist the user in moving the second frame into the desired position.
