A portable and kinetic motion resistance upper body invention that can be used for a variety of exercises. This invention combines dial tension adjustment clutch sheaves, a variable linear tract bearing and a one piece resistance shock-cord, together these core components achieve a unique minimal impact work-out. The multi-motion and changeable adjustments for this invention, result in a wide variety of muscular stimulation and therapeutic exercises that are non-existent in the fitness and health industry. The outcome of the mechanism can be customized for a particular sport requirement or physio and other therapeutic restorations, or even for case specific industrial and robotic counter-balancing controls. This invention is can also be used as a lift-assist device.

This invention offers a rowing machine's mechanical resistance device which comprises an electric motor or a solenoid, a programmable control means and a custom algorithm, controlling the programmable controls means. It eliminates the compromising effect of backlash between the rower's handle and the resistance imparting device. This backlash is present between the power and the idle phases of rowing strokes on all state of the art rowing machines comprising flywheels. Ultimately, this invention allows all rowers to improve their rowing form and avoid injury.

A rope exercise simulation device comprising: a handle and an elongate housing with at least one internally located displaceable weight; wherein the housing extends substantially orthogonally with respect to an axis of the handle and the at least one weight is arranged to move between the ends of the housing acting against one or more resiliently deformable means.

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 aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. Since an essential feature of treadmill is the concave shape of the running surface of belt in its respective upper portion, the treadmill configurations insure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers.

A manually operated treadmill is provided that includes a treadmill frame having a front end and a rear end opposite the front end, a front shaft assembly rotatably coupled to the treadmill frame at the front end, a rear shaft assembly rotatably coupled to the treadmill frame at the rear end, and a running belt disposed about the front and rear shaft assemblies, wherein the running belt defines a curved running surface upon which a user of the treadmill may run. The treadmill also includes an incline adjustment system movably coupled to the treadmill frame for moving at least one of the front end and the rear end relative to a support surface, wherein increasing a height of the front end relative to the rear end and the support surface increases a running speed that a user can achieve on the running belt.

An exercise apparatus having a pulley, a pair of stabilizing assemblies each configured to couple a front portion of a respective pedal element to each side of the pulley, a looped belt configured to couple the pulley to a resistance assembly, a tension stabilizer configured to maintain a tension of the looped belt on the pulley, and the resistance assembly configured to assert an adjustable resistance to the pedal elements through the looped belt. The exercise apparatus also comprises a resistance band extension for performing additional exercise using resistance bands and a transport mechanism for transporting the exercise apparatus and securing the exercise apparatus to a chair wheel or other structure during exercise.

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.

A training apparatus having a progress indicator and unified base for different apparatus types, such as for an ergometer, speed bike, recumbent bike, home training bike, rowing apparatus, elliptical trainer, cross-trainer or treadmill. The fitness apparatus of every apparatus type is based on a structure which is unified in terms of technical design, according to which the frame or pedestal of the fitness apparatus has rollers which are arranged on the frame or pedestal such that a tilt-stable positioning of the frame with respect to the subsurface and a longitudinal displacement of the frame or of the frame together with the pedestal relative to the subsurface is enabled by means of an actuator depending on the measure of success of the user training.
