In some embodiments, two or more different types of stator structures may be disposed within a gap of an axial flux machine. Such arrangements may be advantageous, for example, for producing a machine optimized for multiple modes of operation, such as mechanical torque generation, conversion of mechanical torque to electrical power, and/or dissipation of mechanical power. Further, in some embodiments, an axial flux machine may include a planar stator having a winding arranged to be positioned within the machine's active region, and may further include at least one switch configured to be selectively closed to establish an electrical connection between respective ends of the winding at a time that the winding is not coupled to an external power source.

A fitness machine with continuously variable magnetic-controlled damping force and combined with a manual emergency brake includes a fitness bike, a console, a magnetically controlled damping device and a resistance and brake control device. The fitness bike generates and supplies power to the console, magnetically controlled damping device and resistance and brake control device by a rotating flywheel. The magnetically controlled damping device produces continuously variable electromagnetic damping force to the flywheel. The resistance and brake control device allows a user to operate in two different modes of the continuously variable electrically controlled brake and manual emergency brake, and the function of the continuously variable electrically controlled brake may control the flywheel to produce continuously variable electromagnetic damping, so as to achieve the results of generating and supplying the required electric power, providing the continuously variable controlled damping force of the fitness bike, and combining a gradual-change brake and a multifunctional brake.

A step exercise apparatus with a self-centering pedal system. The system comprising a frame and a seat supported from the frame. A first pedal assembly and a second pedal assembly are pivotally supported from the frame positioned so as to be manipulable by a user seated in the seat. A linkage is positioned in communication with the first pedal assembly and the second pedal assembly such that movement of either pedal assembly in a first direction causes movement of the other pedal assembly in a second direction opposite of the first direction. A brake is preferably employed for resisting motion of the first pedal assembly and the second pedal assembly in at least the first direction. A centering system positions the first and second pedal assemblies in a substantially central position when not being manipulated by the user.

An exercise treadmill includes a machine body, which has at least two rollers, a flywheel linked with one of the two rollers, a support assembly mounted between the two rollers, and a running belt fitted around and engaged with the two rollers and arranged around the support assembly. The exercise treadmill is provided with an accelerating means so that, while a user is walking or running on the machine body, the treading force provided by the user allows the running belt to be accelerated to move around the two rollers for generating electrical power. In addition to improving body heath, the electrical power produced by the treadmill in the training activity can reduce the electrical consumption of city power.

A hand-held exercise device comprises a frame, a handle attached to the frame, a spool element pivotally mounted to the frame, a pull-cord movable between a wound configuration in which the pull-cord is wound around the spool element and an unwound configuration in which the pull-cord is unwound from the spool element, a resistance element pivotally mounted to the frame, a transmission that couples the pull-cord to the resistance element such that pulling the pull-cord from the device causes the resistance element to rotate, and a damping means that acts to slow the rotation of the resistance element. The device provides a compact and lightweight form of exercise equipment that is easy to carry and easy to store. The device can be used with various fixtures, and also with a second handle fixed to the pull-cord, to allow the user to perform a wide range of exercises. Preferably the exercise device transmits exercise data to an external device that provides feedback and guidance to the user. A resistance mechanism for exercise apparatus allows a pull-cord to be coupled to a resistance element such that pulling the pull-cord from the mechanism causes the resistance element to rotate. A drive element is driven by a frictional force between the drive element and the pull-cord. The resistance element is coupled to the drive element by a transmission.

A resistance exercise system having, in certain embodiments, a DC power supply system, a DC motor connected to the DC power supply system, a drive section connected to a drive element, a resistance delivery element connected to the drive element, and an extractable exercise resistance delivery section, a predetermined variable resistance section intermediate the DC power supply system and DC motor, an electrical condition sensor, and a variable resistance section control in communication with the electrical condition sensor and the predetermined variable resistance section. In some embodiments, the resistance exercise system includes a computing facility providing the ability to configure the exercise system to provide predetermined static or variable exercise resistance during exercise, and for example, during a positive or negative exercise stroke. Some embodiments allow users to create and, if desired, display varying and complex resistance exercise routines with or without use of resistance weights.

Disclosed is a technical training garment configured for use with modular, interchangeable biomechanics units and or resistance modules. The garment may provide resistance to movement throughout an angular range of motion and or tracks a variety of biomechanical parameters such as stride length, stride rate, angular velocity and power expended by the wearer. The garment may be low profile, and worn by a wearer as a primary garment or beneath or over conventional clothing or athletic uniform. The device may be worn as a supplemental training and or diagnostic tool during conventional training protocols, or as a biomechanics or biometric data capture device during competition.

Example embodiments relate to a system, method, apparatus, and computer readable media configured to generate a multiple renditions of a user interface that is updated based upon athletic movements of two or more users remotely located from each other. The UI may be configured to simultaneously display energy expenditure values in real-time. In further embodiments, a joint energy expenditure values determined from multiple remote users may be simultaneously displayed.

Improvements to a desk and exercise semi-recumbent bicycle is disclosed, the desk allows a person exercising while utilizing the desk with a computer, as a table or read a book. The desk has a 6-way adjustment relative to the seat for elevation of the desk, angle, sliding forward and backward of the desk or the proximity of the desk relative to the chair and or the pedals. The desk pivots to allow the desk to be easily tilted towards the user when they are studying and tilted away from the user when the user wants to exit the exercise bicycle. The dimension from the seat to the pedals is adjustable to accommodate these different desires. The amount of resistance can be adjusted to increase or decrease the difficulty to accommodate different levels of activity. A recording mechanism can count distance, elapsed time, calories or other information.
