Various improvements in fitness devices are disclosed. In an embodiment, a method is disclosed including reading performance data from an exercise device; adjusting a visual output of one or more visual output devices (VODs) attached to a mechanical element of the exercise device; and synchronizing the visual output of the one or more VODs in response to a change in the performance data.

An exercise system that may be rail-less, frameless, and/or portable is described. The exercise system includes a carriage having a plurality of wheels and a stationary platform. The stationary platform is independent of and separate from the carriage, and the stationary platform is freestanding. At least one tension member having a first end is attached to the carriage and a second end is detachably attached to the platform such that the carriage is movable on a horizontal plane parallel to a ground surface while the stationary platform remains in a fixed position.

Portable fitness monitoring methods are disclosed. In an embodiment, a portable fitness monitoring method includes a method for providing audible output to a user during an athletic activity using a portable fitness monitoring device. The method includes the steps of receiving an audio feedback file package that includes a first audio feedback file, updating the audio feedback file package, and processing the updated audio feedback file package to provide audible output to the user through an audio output device during the athletic activity.

An exercise storage system includes a storage compartment including at least one storage element. Exercise equipment is stored on the storage elements. A door is connected to the storage compartment with a hinge such that the viewing angle of the door is adjustable. A display on the door includes a backlit display and a mirrored display. A user may select exercise equipment from the storage compartment and perform an exercise activity while viewing the display.

An exercise machine may include a reciprocating linkage that supports one or more pedals configured to move in a closed loop (e.g., elliptical) path as a user exercises with the machine. The exercise machine may be adjustable to vary a characteristic of the exercise provided by the machine, for example by changing an incline of a rail supporting the reciprocating linkage, and thus an angle of the closed loop path. The exercise machine may vary the incline with a lift mechanism operatively associated with the front upright frame of the machine, which may also support a resistance assembly, all in a compact form factor that may be more aesthetically pleasing and practical for relatively smaller exercise spaces.

An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.

A system and methods for custom-fitting golf clubs and golf club components is disclosed. Data is generated by a tracking device as a plurality of golf swings are performed by an individual. The data comprises motion and orientation information associated with a golf ball and with a golf club. The data is displayed using a graphical user interface. A plurality of shot characteristics is determined from the data. The shot characteristics are used to recommend golf clubs and golf club components that adjust a golfer's swing where the golfer exhibits the plurality of shot characteristics.

A treadmill includes a deck having a continuous track, and a plurality of slats fixedly connected to the track. The treadmill also includes a first post extending from the deck, a second post extending from the deck opposite the first post, and a first arm supported by the first post and including a first rotary control. The treadmill further includes a second arm opposite the first arm and supported by the second post. The second arm includes a second rotary control separate from the first rotary control. The first rotary control is configured to control a first function of the treadmill and the second rotary control is configured to control a second function of the treadmill different from the first function.

A cordless treadmill including a frame, a belt system. and a drop-in cartridge is disclosed. The cartridge includes a plurality of staggered rollers configured to provide tactile feedback to the user. The frame is adapted to receive the belt system and the cartridge as they are lowered into the frame, and the frame is adapted to place the belt of the belt system into tension as the belt system is lowered into the frame. An integrated flywheel generator system provides smooth operation of the treadmill and generates electricity to power additional systems.

Proposed is an exercise platform for rehabilitation management and, more particularly, an exercise platform for rehabilitation management that estimates maximal oxygen uptake (VO2max) through a sensor being able to acquire condition data of a user and that adjusts exercise intensity of the user in accordance with the estimated maximal oxygen uptake (VO2max).
