Abstract: An exercise treadmill is disclosed. The treadmill can be constructed with no obstructing front rails, with one or more side rails, and/or with a structural flat or ramped surface at the front allowing the user to exercise with unconstrained motion. The treadmill can further include one or more accommodations to help the user stay safe, remain longitudinally centered, and/or adjust speed with controls built into the treadmill, or automatically based on body position relative to sensors built into the side rails. The treadmill belt may be motor driven, or be user driven and dynamically moderated by resistance. The treadmill configuration can be utilized to provide a virtualized exercise experience for the user.

Abstract: In an exercise machine, foot platforms may travel in inclined circular paths to establish three dimensional operational characteristics. Platform support members may be rotationally synchronized by connected mechanical components such that they are maintained out of phase with each other by one half of a cycle or 180 degrees in counter rotational directions. Crank synchronization in an inclined plane during operation of the exercise machine may provide three-dimensional foot travel in vertical, lateral and longitudinal directions.

Abstract: A variable stride exercise apparatus may provide a novel linkage assembly and corresponding exercise apparatus suitable for linking circular motion to relatively more complex, generally elliptical motion. Left and right cranks are rotatably mounted on a frame. A foot supporting linkage is movably connected between a rocker and the left and right cranks in such a manner that may provide variable paths of motion controlled by a user of the apparatus.

Abstract: An exercise apparatus comprises a main body with a cavity that can be selectively covered with a lid. The main body is angled to increase the range of motion of a user of the apparatus. At least a portion of the lid is selectively housed within the cavity. A smaller scale embodiment of the exercise apparatus can be utilized as a sitting apparatus that corrects posture while a user is in a seated position. A method of exercise comprises a variety of steps which can be performed by a user while the user remains on his or her back.

Abstract: Gymnastics gear for performance of gymnastic exercises, where the gymnastics gear comprises at least a twisting belt, where the twisting belt comprises a first ring, typically an outer ring, and a second ring, typically an inner ring, where the two said rings are concentrically joined and can rotate in regard to each other about a common axis, where the first ring furthermore comprises at least two connection devices, where said connection devices are preferably arranged symmetrically at the outer periphery of the first ring and adapted for joining to a high-tensile or elastic rope, where the second ring also comprises connection devices at the periphery, where these connection devices are adapted for direct or indirect mounting of connection elements to a somersault belt, where the somersault belt is an inflatable somersault belt comprising at least one chamber and at least one valve, which achieves both a good centering of the somersault belt and a good tightening to the body of the gymnast, and where one a

Abstract: A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse wooden, plastic or rubber slats attached to each other in a resilient fashion, wherein each transverse slat has at least one continuous fin descending downward therefrom.

Abstract: Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks that are arranged in parallel at an interval, a second track movably connected to the pair of first tracks, a hand holder that is movably provided in the second track and on which a hand and an arm of a user is held, and a stopper for a track provided in at least one of the first tracks and the second track to limit movements of the second track and the hand holder.

Abstract: A treadmill safety system that detects the runner or treadmill user without the need for attaching a string to the runner. It includes two basic components: 1) a distance or proximity sensor, laser, ultrasonic, IR, or other and 2) a method to kill treadmill power in the case the runner is not detected in position by the sensor. This can be by deactivation by electromagnet as in present treadmills, interruption of main power, or by any other method.
