An exercise device includes a frame, an upright portion of the frame, a movable element connected to the frame and movable in the performance of an exercise, a first display connected to the upright portion of the frame, and a second display connected to the frame.

A rowing simulation trainer includes a base frame, a pulling unit, an inertia wheel unit and a guiding unit. The pulling unit includes a shaft, a first belt wheel, two cord wheels, two pulling cords, two handgrips and two elastic coiled plates. The guiding unit includes two mounting tubes. Each of the two pulling cords extends through one of the two mounting tubes. Thus, the two cord wheels and the two pulling cords cooperate to drive the inertia wheel unit and are respectively operated independently without interfering with each other. In addition, the two pulling cords are limited by the two mounting tubes so that the two pulling cords are kept in line with and will not be deflected from the two cord wheels.

A free weight assembly includes a cradle, an aerobic exercise element that is movable with respect to the cradle during the performance of an exercise, at least one free weight removable from the cradle, an input in communication with a processor that determines a time to instruct a user to remove the free weight, and an indicator that activates when the time to remove the free weight arrives.

A treadmill includes a platform where the platform includes a first side panel and a second side panel spaced apart at a distance from the first side panel, and a gap defined between the first side panel and the second side panel. The treadmill also includes a running deck contained within the platform and exposed within the gap, a first pulley connected to the running deck, a second pulley connected to the running deck opposite the first pulley, a tread belt surrounding the first pulley and the second pulley, a first post removably connected to the platform, a second post removably connected to the platform, and a first rail transversely connected to the first post and the second post.

An exercise device includes a frame, a movable engagement surface connected to the frame and movable in the performance of an exercise, and a display located adjacent to or below at least a portion of the movable engagement surface.

A rowing machine includes a frame where the frame includes a first support, a second support, and a beam extending between the first support and the second support. A track is defined by at least a portion of the beam, and a sliding member is movably disposed on the track. A hinge joint is disposed in the beam between the first support and the second support defining a first section of the beam and a second section of the beam.

An electricity generating system using fitness equipment, wherein the fitness equipment can be used to produce electricity with a generator. The electricity produced can be transferred from the generator to a splitter. A controller can be used to receive identifications and decisions on transfer of the produced electricity from a fitness center. The controller can be used to track in real time electricity produced as watts or as amperage associated with a user identification, a fitness class identification, or an administrator identification input less than 10 minutes before the electricity is produced or at a preset time, which can then transfer in real time energy credits equivalent to electricity produced or transfer produced electricity to a destination designed in the a user decision, a fitness class decision, or an administrator decision.

Tracking and monitoring athletic activity offers individuals with additional motivation to continue such behavior. An individual may track his or her athletic activity by completing goals. These goals may be represented by real-world objects such as food items, landmarks, buildings, statues, other physical structures, toys and the like. Each object may correspond to an athletic activity goal and require an amount of athletic activity to complete the goal. For example, a donut goal object may correspond to an athletic activity goal of burning 350 calories. The user may progress from goal object to goal object. Goal objects may increase in difficulty (e.g., amount of athletic activity required) and might only be available for selection upon completing an immediately previous goal object, a number of goal objects, an amount of athletic activity and the like.

Among other things, a rowing technology includes a first rowing machine having an electromagnetic brake providing a resistance to a rower of the machine in each rowing stroke of a series of rowing strokes of the rower An electronic controller causes the resistance of the electromagnetic brake to vary over each rowing stroke in a profile that emulates resistance to which another rower in a shell on water or on a second rowing machine is subjected in each rowing stroke of a corresponding series of rowing strokes.

The present invention is a portable rowing machine that allows a user to perform rowing, skiing, paddling, or any other physical activities at any suitable location. The portable rowing machine contains a housing, a pulley, a flywheel, a planetary gear assembly, an anchor, a retraction mechanism, and a pull cord. The housing contains a central gear support. The pulley, the flywheel, the planetary gear assembly, and the retraction mechanism are positioned within the housing. The central gear support is positioned within the housing. The planetary gear assembly is positioned within the central gear support. The pulley and the flywheel are axially connected opposite to each other along the planetary gear assembly. The retraction mechanism is operatively connected to the pulley, where the retraction mechanism is configured to retract the pull cord into a spooled state around the pulley. The anchor is externally connected to the housing.
