A training equipment for resistance training of the upper body, wherein the training equipment comprises: an attachment portion adapted to be attached to the body of an exercising person, a handle portion adapted to be gripped by the exercising person, a first distance device flexibly attached in the attachment portion by a first joint, a second distance device flexibly attached in the first distance device by a second joint. At least one of: the first joint, the second joint, the first distance device, and the second distance device comprises an adjustable movement resistance device adapted to create an adjustable resistance between the attachment portion and the handle portion, so that training of the upper body is obtained upon movement of the handle portion.

A system and method to provide haptic and visual feedback of motion of the skier foot and the forces transmitted to the skiboot insole and consequently to the ski/snow interface. This system comprises a motion and force sensors and a haptic actuator embedded in the skiboot insole in communication with a smart-phone based analysis application, configured to calculate insole motion and orientation and the distribution of pressure points inside the skiboot, then to provide haptic feedback to the skier foot instructing on timing and direction of change in the pressure points necessary to achieve optimal turn parameters. Furthermore, analyzed together with GPS coordinates are transmitted by the application to the cloud based server for further processing. Graphical and numerical representation of data is superimposed over a 3D map of a slope which may be viewed on the user smart-phone or on a remote computer terminal.

A method and device are provided that allow a competent skier to train and/or assist a trainee downhill skier with the acquisition of basic downhill skiing techniques. The trainee skier is tethered to an uphill instructing skier by a pair of reins attached to the trainee at the ankles, ski tips, or to the ski tips via ski tip handles. The instructing skier has substantially independent control over each tethering point to assist or train the novice skier to execute turns, control speed, and promote proper balance and stance for the maneuver and terrain at hand. The method and device may also comprise the use of adjustable ski tip couplers that limit divergence, and optionally convergence, of the trainee's ski tips. Handicapped skiers may be assisted and guided in downhill skiing using this method and device.

An exercise machine includes a frame and a resistance mechanism attached to the frame. A crank assembly is in mechanical communication with the resistance mechanism, and the crank assembly includes a crank axle, a crank arm connected to the crank axle, and a roller connected to a distal end of the crank arm. A first pedal assembly is movably attached to the crank assembly and movable in a performance of an exercise. A second pedal assembly is movably attached to the crank assembly and movable in the performance of the exercise. Each of the first pedal assembly and the second pedal assembly include a pedal beam and a first tensioned element spanning at least a portion of an underside of the pedal beam. At least a portion of the resistance mechanism is disposed between the first pedal assembly and the second pedal assembly.

An exercise machine includes a frame and a resistance mechanism attached to the frame. A crank assembly is in mechanical communication with the resistance mechanism, and the crank assembly includes a crank arm, a roller connected to the crank arm, and at least one internal load bearing surface integrated into the roller. A pedal assembly is movably attached to the crank assembly and movable in a performance of an exercise. The pedal assembly includes a pedal beam and a tensioned element that spans a first portion of an underside of the pedal beam. The tensioned element guides the roller with at least one internal load bearing surface during the performance of the exercise.

An exercise apparatus, system, and method include a board with adjustable bumpers having shock-absorbing systems and user-adjustable bumper push-off angles. A counterforce and guiding system, providing an amount of counterbalance force corresponding to an amount of force by an amount of a user lean during a sliding motion, while simultaneously providing an amount of a guiding force from a harness not affixed statically to a user allowing a gliding motion along a path, with a guideline to guide an amount of a user motion to correspond to user-selected path of motion on the top sliding surface as the user slides, that results in the user to simulate, a body dynamic of a naturally occurring posture and motion of a human's body optimized for performing the motion that corresponds to the user-selected path of motion.

An exercise machine platform that allows for emulation of the natural movements of real-world modes of transportation in stationary exercise machines such as bicycles, rowing machines, elliptical machines, and treadmills. The exercise machine platform comprises a base with one or more powered lifting mechanisms, a frame supported by the lifting mechanisms of the base which allows for roll, pitch, and/or vertical displacement movements, and a rocker plate supported by the frame that allows for additional independent movement from the roll, pitch, and/or vertical displacement movements of the frame. A dampening system controls the additional independent movement between the frame and rocker plate.

A system or method for displaying a video segment recorded by a camera device on a display device disposed remotely from the camera device. Video segments may be transmitted over a network to a remote viewing location. Video segments sent from a plurality of camera devices may be compiled by a server and displayed on a single display device. Video segments may auto-scroll such that a user need not interact with this display device to begin playback of a video segment. The technology may be used for such purposes as an athlete reviewing videos captured by one or more coaches or spectators.
