A method includes causing display, during a first time period and via a first set of multiple smart mirrors, of live video depicting at least one user associated with the first set of multiple smart mirrors, without displaying a workout video. The method also includes causing display, during a second time period following and mutually exclusive of the first time period, and via a second set of multiple smart mirrors, of a workout video and a representation of at least one user associated with the second set of smart mirrors. The method also includes causing display, during a third time period following and mutually exclusive of the second time period, and via a third set of multiple smart mirrors, of live video depicting at least one user associated with the third set of multiple smart mirrors.

During a first time period and for a first user, a second user is automatically selected based on competitive data of the first user and competitive data of the second user, and a workout selection is sent to cause a video of a workout to be displayed during a second time period on a smart mirror of the first user and a smart mirror of the second user. During the second time period, a live stream of the first user exercising is displayed at the smart mirror of the second user, and a live stream of the second user exercising is received and displayed at the smart mirror of the first user. During the second time period, a performance score of the first user and a performance score of the second user is displayed at the smart mirrors of the first user and the second user.

A processor-implemented method includes receiving a request that specifies a workout performed at a first time, a list of users, a second time after the first time, an overlay to be displayed during a rebroadcast associated with the request, and a skill level of the workout. The request is compared to calendar data, and a session acknowledgment message is sent to the compute device of the first user based on the comparison. An invitation message is sent to compute devices of a second user and a third user, identifying the second time, and invitation responses are received from the second user and the third user. In response to the invitation responses, a video of the workout is rebroadcast at the second time, to a smart mirror of the first user, a smart mirror of the second user and a smart mirror of the third user.

A physical fitness system includes a stand assembly including a stand, a computing device mounted on the stand, and at least one integrated docking station for receiving an exercise device. At least one exercise device is configured to be releasably mounted to the docking station. Upon receiving instructions from a user input on the computing device, the system computer processor is configured to transmit instructions over the network from a system network communication interface to an exercise device network communication interface, and upon receiving the instructions, the exercise device processor is configured to activate a driver in the exercise device to change either the resistance applied to the exercise device or the weight carried by the exercise device.

A pull-up fitness exercise machine with a remote intelligent control device, comprising a base stably supporting all components of the invention, a vertical support fixed behind the base, a set of top cantilevers projecting from the vertical support and having a holding crossbar for exercise, and a multi-swiveling rod assembly pivoted below the vertical support and having a horizontal support plate. The multi-swiveling rod assembly is further connected with an auxiliary pushing unit that can adjust the pushing force, so as to provide the multi-swiveling rod assembly with a proper upward pushing force. By using a microcomputer intelligent control device with built-in control software and an operating interface in cooperation with more than two sets of position detectors, the multi-swiveling rod assembly and the auxiliary pushing unit of the pull-up fitness exercise machine can be intelligently controlled. Moreover, the microcomputer intelligent control device is provided with a Bluetooth networking system and a Wi-Fi networking system for remotely controlling the intensity of the pushing force of the pull-up fitness exercise machine.

There is disclosed a system for engaging in exercise. The system includes a removable resistance device suitable for temporary installation into multiple, separate exercise devices. When installed in the separate exercise device, the resistance device is operable under control of a computing device to selectively increase or decrease resistance applied to the separate exercise device and to thereby selectively increase or decrease the difficulty of an exercise associated with the separate exercise device.

A modular and dynamic force apparatus for adjusting standard and dynamic torque-to-linear forces during physical activity in real-time, the apparatus including a force module, a user device and an apparatus tracking processing unit. The force module includes an open hub attachment point, wherein the open hub attaches the apparatus to an external source, one or more sensors measuring data for physical activity efficiency, an internal processor, wireless radio and force sensor module, a variable length cable, a force generating component, and motor controls. The internal processor, wireless radio and force sensor module includes an apparatus tracking measurement unit (“ATMU”) adapted to measure data, a first electronic communications channel for transmitting the measured data to an apparatus tracking processing unit (“ATPU”), and a second electronic communications channel for transmitting one or more apparatus conditions data to adjust dynamic forces.
