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.

A self-powered vibration mechanism is provided that can be mounted on an existing pedal shaft yet operates independent from the existing pedal. Mechanical isolation or mechanical decoupling permits transferring the vibrating energy to the foot rather than to the pedal shaft and the bicycle. In another embodiment, a full removable pedal with self-powered vibration mechanism can replace an existing pedal.

In response to physical connection of an exercise accessory with a portion of an exercise machine, an identifier of the portion of the exercise machine is received. A signal including the identifier of the portion of the exercise machine is transmitted.

An exercise machine and a dual resistance structure combining wind resistance and magnetic resistance are disclosed. The dual resistance structure combining wind resistance and magnetic resistance includes a rotating shaft, a wind resistance unit, and a magnetic resistance unit. The wind resistance unit is disposed on the rotating shaft, and includes blades arranged annularly. Each blade has a notch recessed in an axial direction of the rotating shaft. The magnetic resistance unit includes a magnetic resistance member and a magnetic resistance wheel. The magnetic resistance wheel is disposed on the rotating shaft. The notch of each blade faces the magnetic resistance wheel to form a moving space between the magnetic resistance wheel and the notch. When the magnetic resistance member is moved relative to the magnetic resistance wheel along a radial direction of the magnetic resistance wheel, part of the magnetic resistance member is movable in the moving space.

A walking assist device includes: a pair of right and left handles that are movable back and forth with respect to a frame in accordance with arm swing performed during walk of a user; rails on which the handles are provided and which limit movement of the handles in a movable range in accordance with arm swing performed during the walk of the user; a handle information acquisition unit that acquires information related to movement of the handles; and a control unit that controls a drive unit in accordance with the information from the handle information acquisition unit.

This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

A rowing exercise device comprises a support structure; a movable user support movably associated with the support structure for movement relative to the support structure; a movable foot support movably associated with the support structure for movement relative to the support structure; a handle; and a rowing assembly operatively associated with the handle and at least the movable foot support to cause at least the movable foot support to move relative to the support structure with movement of the handle so that both a user s body and one or both feet move relative to the support structure with movement of the handle.

Control system of a cycling simulation device, said device comprising a support frame, with which a user carries out training by acting on the pedals of said bicycle, a flywheel rotating around a main shaft, connected to said coupling members, and a braking device, acting on said flywheel, comprising: a control logic unit, capable of connecting in transmission and reception with a remote device, by which a user can set one or more training parameters, and a torque sensor for detecting and sending to said control logic unit a signal related to the torque acting on said main shaft during the rotation of said flywheel, and said control logic unit being configured so as to adjust the braking force exerted by said braking device on said flywheel as a function of training parameters and of signal related to the torque acting on said main shaft detected by torque sensor.

A treadmill includes a running belt defining a non-planar running surface, and a motor operatively coupled to the running belt. The treadmill is operable in plurality of operating modes to control a user experience.
