A user interface for an interactive exercise system includes a display module held by a mechanical support system, with the display module able to display a video of a trainer. The trainer can be presented in full body view against a black background and a mirror element attached to at least partially cover the display module.

Devices and computer technology are configured to enable enhanced simulated bicycle steering for use with a stationary training system. For example, one embodiment includes a device configured to support and enable simulated steering of a bicycle front wheel, for use with a stationary training system, optionally including a sensor device configured to provide a steering signal for user by a bicycle simulator software application. Further embodiments include computer technology configured to provide bicycle simulation functionality, including steering. Simulation of steering is in some embodiments based on a combination of handlebars turning and bicycle tilt, and may account for counter-steering motions.

A system and method provides real-time coaching and adjustment to training. A wearable device may be configured for over-the-ear wear, which includes a speaker, a transceiver, and sensors to measure biometric activity in the user while worn during athletic performance training. The system uses a method which compares past performance to current performance and training goals to adjust a training plan during performance for maximizing training results. The system analyzes current and past performance and generates new training performance output goals in real-time based on the user's current performance. The system then transmits coaching output during a live training session instructing the user on how to adjust their performance output during a current training session. Some embodiments include connecting to smart gym apparatus which connect to the system and automatically increase/decrease resistance/speed depending on the system determining a need to change performance output for maximum gains.

Various example embodiments relate to a respiration guidance device including: an outer casing configured to change shape; and a drive unit located within the outer casing and configured to change the shape of the outer casing according to a desired breathing pattern; and the outer casing has at least one slit dividing the outer casing into at least one portion displaceable with respect to a remaining portion of the outer casing; and the drive unit is configured to change the shape of the outer casing by displacing the at least one portion.

A system operates to manage accessibility of media content items based on a user's performance of a repetitive motion activity. The system can generate rule data based on a rule designed to permit access to certain media content items. The rule data can include information about various conditions to be satisfied to make the media content items accessible for playback. Such conditions can be associated with a user's performance or status of a repetitive motion activity.

A treadmill system includes a deck, an endless tread belt covering at least a portion of the deck, a position sensor that senses a position of a user when the user is on the tread belt, and a control module that adjusts a speed of the tread belt in response to an output of the position sensor.

Systems and methods for controlling application of horizontal resistive force to a user walking on a treadmill to provide substantially constant force even if the user changes his or her relative position on the treadmill. The systems and methods can improve the user experience when force is applied while also improving user safety. The system has a cable, a motor, and a system controller. The cable can be coupled to a harness to apply a horizontal resistive force to a treadmill user, and the motor can be coupled to the cable and configured to apply a motor force to the cable. The cable can have an adjustable operative length. The system controller can have a processor communicatively coupled to the motor and configured to adjust the force applied by the motor in response to changes in cable length and a measurement of the actual force applied by the cable.

A media-playback device includes: a media-output device that plays media content items; a physiological measurement device programmed to measure at least one physiological measurement of a user of the media-output device; and a physiological control engine configured to: identify a current physiological measurement for the user; and cause the media-output device to modify playback of the media content items based upon the current physiological measurement.

Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a signal responsive to a cyclically-varying arterial blood flow at a location on a head of a user; providing a recurrent prompt at a frequency of the heart pump cycle using the signal, such that the signal correlates with a magnitude of blood flow adjacent to the location, and the recurrent prompt is provided to guide the user to time performance of a component of a rhythmic musculoskeletal activity with the recurrent prompt; and guiding the user to adjust a timing of the component of the rhythmic musculoskeletal activity to substantially maximize a magnitude of the signal. In some embodiments, the method further includes generating the recurrent prompt by amplifying the sound generated by the blood flow in or in proximity to an ear of the user.

Disclosed are various approaches for determining the maximum oxygen consumption of a person, also known as maximum aerobic capacity or VO.sub.2 Max. A person is positioned on a treadmill. Attached to the person is a harness configured to apply a horizontal force to the person. A work rate for the person can be calculated based at least in part on the magnitude of the horizontal force applied by the harness and the velocity of the belt. The maximum oxygen consumption for the person can then be calculated based at least in part on the previously calculated work rate.
