A treadmill may include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, and a runaway mitigation mechanism in at least indirect mechanical communication with the motor. The runaway mitigation mechanism at least mitigates a motor runaway condition.

A computing system causes instructional media to be played on a device to a user. An instructor in the instructional media provides guidance as to how to perform an activity when the instructional media is played on the device. The computing system obtains user data pertaining to performance of the activity by the user. The computing system generates a user-customized portion of the instructional media based upon the user data and a computer-implemented model. The computing system causes the user-customized portion to be played on the device to the user, where the device emits audible words reproduced in a voice of the instructor, where the audible words are based upon the user data, and further where the device displays generated images of the instructor depicting the instructor speaking the audible words as the device emits the audible words.

Methods and systems for calibrating a level of intensity of a fitness exercise given a target effort value facilitate optimal exertion for an individual performing the fitness exercise. An instantaneous effort value is determined based on measured real-time and historical data and communicated to the individual. An aspect of the fitness exercise is adjusted based on a difference between the instantaneous effort value and a target effort value.

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.

A workout music playback device for playing workout music during a workout with given workout parameters by arranging and assembling song segments of original musical recordings in accordance with workout parameters. The device has a media output manager configured to receive the workout parameters and prepare audio output information by arranging a sequence of song segments into an edited song recording. It has an instruction relay module configured to receive the audio output information, and transmit the workout audio output instructions. The device has a media output generator configured to receive the audio output instructions from the instruction relay module, retrieve and assemble the song recording data of the original musical recording from the memory in accordance with the audio output instructions, and transmit a data stream of workout music corresponding to the workout parameters.

Systems and methods for identifying a condition of a user. A treatment apparatus is configured to be manipulated by the user for performing an exercise, and an interface is communicably coupled to the treatment apparatus. One or more sensors are configured to sense one or more characteristics of an anatomical structure of the user. A processing device and a memory is communicatively coupled to the processing device. The memory includes computer readable instructions, that when executed by the processing device, cause the processing device to: receive, from the sensors, one or more sensor inputs representative of the one or more of characteristics of the anatomical structures; calculate an infection probability of a disease based on the one or more characteristics of the anatomical structures; and output, to the interface, a representation of the infection probability.

A method of varying a dynamic resistive force during a strength training exercise includes receiving a selection of the strength training exercise from a set of available strength training exercises and obtaining exercise logic for the strength training exercise from computer memory. The exercise logic provides instructions for generating a vector that defines the dynamic resistive force provided at an end effector of a strength training apparatus during the strength training exercise. The method includes determining a real-time geometric arrangement of a plurality of cables coupled to the end effector, generating, based on the real-time geometric arrangement of the plurality of cables and the exercise logic, time-varying operating setpoints for a plurality of actuator assemblies coupled to the plurality of cables, and exerting the dynamic resistive force at the end effector by controlling the plurality of actuator assemblies in accordance with the time-varying operating setpoints.

An interactive exercise apparatus for guiding a user to perform an exercise includes a frame, a mirror, a display device, a driving mechanism, and a control unit. The mirror is movably mounted on the frame and configured to reflect an image of the user. The display device is disposed on a backside of the mirror and visible through the mirror. The driving mechanism is configured to drive the mirror to move with respect to the frame. The control unit is operable to control the driving mechanism according to a location of the user so as to control the mirror to move to a suitable position where the user can see their reflected image.

A method that includes receiving treatment data associated with a user capable of using a treatment device to perform a treatment plan. The method also includes receiving user related data (URD) associated with the use and receiving alignment data associated with the user while the user engages in at least one activity. The method also includes identifying, based on at least the treatment data, the URD, and the alignment data, at least one alignment characteristic associated with the user and modifying at least one aspect of the treatment plan in response to receiving, from a healthcare professional, treatment plan input including at least one modification to the at least one aspect of the treatment plan.

Example systems, devices, media, and methods are described for presenting a virtual guided fitness experience using the display of an eyewear device in augmented reality. A guided fitness application implements and controls the capturing of frames of motion data using an inertial measurement unit (IMU) and video data from one or more cameras. The method includes detecting exercise motions (with or without equipment) as well as detecting and counting repetitions. Relevant data about detected motions or equipment is retrieved and used to curate the guided fitness experience. A current rep count is presented on the display along with an avatar for playing messages, performing animated demonstrations, responding to commands and queries using speech recognition, and presenting guided fitness instructions through text, audio, and video.
