A protective rowing device for compression of the abdomen is provided that comprises a brace and U-shaped support member that may connect to a rowing machine seat and rail.

Examples relate to a system to apply stimuli to a human body. The system comprises a three dimensional display, a stimulation element, a specific piece of clothing, a portable background and a controller. The controller comprises a processor, data storage and an instruction set. The instruction set is to cooperate with the processor, data storage, three dimensional display and stimulation element to display a recorded three dimensional representation of an actor in movement and to transmit to the stimulation element stimuli synchronized with the movement. The actor is wearing a piece of clothing having the same aspect as the specific piece of clothing, the actor being located in front of a background having the same aspect as the portable background, the recording being from the actor point of view.

A training aid stimulator for providing fast perceptive feedback is disclosed. The training aid stimulator includes a first skin electrode and a second skin electrode both for making electrical contact to the body of a user, a charging module, a discharge module connected to one or more of the skin electrodes for a feedback discharging, and a processor for controlling the charging of a capacitor equivalent to a predetermined first voltage level, wherein the processor further being connected to the discharge module for controlling a feedback discharge of the capacitor equivalent. The stimulator comprises a voltage measurement module for measuring the level of charge of the capacitor equivalent, and the processor is configured for keeping the stimulator ready to discharge by repeatedly measuring the level of charge and by providing a maintenance charging when the voltage over said capacitance equivalent is at or below a predetermined second voltage level.

Disclosed herein are methods of exercising human arms, including a method of exercising human arms that may include: 1) providing an arm exercise assembly, comprising: a) a frame; b) a wheel coupled to the frame; c) two locks disposed on the wheel; and d) a handle coupled to the wheel; 2) coupling the two locks to the wheel; and 3) abutting the handle against one or both of the two locks.

A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises an elongated fabric body sized to encircle a limb of a user, one or more shape-memory wires carried by the fabric body and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, and a micro-processor based controller for selectively actuating the one or more shape-changing elements to reduce the effective diameter of the device encircling the limb, to thereby apply pressure to the limb.

A vertically oriented fitness apparatus utilizes a combination of upper and lower assemblies resistant to vertical motion when the user pushes and pulls against crossbar members of the assemblies vertically. In alternate embodiments of the apparatus, resistance is provided by a dual action dashpot such as an adjustable bidirectional hydraulic damping cylinder which may be used in combination with spring resistance elements. The user is thus able to perform strength training and fitness conditioning exercises for both upper and lower extremities, and their core simultaneously while using the apparatus.

A wearable device such as a garment is disclosed, having at least one sensor, for sensing a parameter. Electronics are provided for processing the sensed parameter, and for providing feedback. Feedback may be in the form of proprioceptive tactile or audible feedback, or in the form of an adjustment of a performance parameter of the wearable device. In one implementation, the processor is configured to activate an effector to provide feedback to the wearer to make a body position correction to bring the position into alignment with predetermined body position reference data.

Fitness apparatus output can be synchronized with media content that features an instructor conducting a workout session. An instructor conducts a workout session while using a recording device to generate media data, and while a computing device executes a client application to generate command data for controlling aspects of output provided by a fitness apparatus. The media data and the command data generated by the instructor can be transmitted to user computing devices over a network. Users may consume the media data on-demand, or as a live stream while the instructor is conducting the workout session. Operations specified in the command data are driven by the timestamps in the media data to synchronize the output provided by a user's fitness apparatus with the visible cues and/or audible cues of the instructor in the media content. The intensity level of the fitness apparatus output may also be customized to the user.
