A fin assembly for aqua resistance exercise comprises a strap having an inner strap and an outer strap, and with fastener(s) provided to an outside of the inner strap and an inside of the outer strap to releasably attach the inner and outer straps together. One or more fins are received on the outer strap and a longitudinal position of the one or more fins is secured by engagement of the inner strap to the outer strap. The length of the inner strap is longer than a length of the outer strap, so that an extending end portion of the outer strap can overlap and engage an opposite end of the outer strap to secure the fin assembly about the user's limb.

A hand paddle. The hand paddle includes a stem having a handle and a blade, which is attached to the stem on either side of the handle. The handle may be attached for operating gentle, yet strenuous, water sports.

Bath for exercising, the bath containing substantially vertical wall portion, and a suitably configured bath bottom, from which extends an exercise base, wherein the bath bottom is formed so that the bath is the deepest in the area where the person lying on the exercise base reaches when moving her legs, the bath is lower in the area where she reaches when moving her arms, wherein the bath bottom is shaped so that in the top view it follows the trajectory of the user can reach when moving her limbs.

An aquatic exercise device and method of use are described herein. The aquatic exercise device provides for a full body, low impact, and decompressing workout that is unattainable by any existing product on the market.

A board paddling training apparatus for assisting in improving a user's paddling technique and strength. In particular, the board paddling training apparatus includes a buoyant board, such as a board adapted for surfing, bodyboarding, paddleboarding, or other board-related sport that entails paddling, and includes a resistance mechanism that creates drag or resistance against a user's paddle stroke. Some implementations of the resistance mechanism can be adjustable in order to create a variety of resistance against the user's paddle stroke and board movement.

A parallel resistance rowing machine is an apparatus that provides adjustable, independent resistance to a user to perform rowing exercises that isolate and emphasize various laterally opposed muscle groups. The parallel resistance rowing machine uses a first resistance assembly and a second resistance assembly mounted to an axle within a chassis. The first resistance assembly and the second resistance assembly are selectably interconnected by a clutch mechanism, enabling a first handle and a second handle to be moved independently or in concert under resistance from the first resistance assembly and the second resistance assembly, respectively. An elongated frame supports a slidable seat assembly, further supporting a full-body rowing action as the user exerts themselves against the first resistance assembly and the second resistance assembly.

An upper and lower body reciprocating arcing motion exercise machine with an adjustable angle user support frame, left and right lower body user support assemblies having foot platforms and shin support pads mounted on an arcing track for movement along rearward and central portions of the user support frame, and left and right upper body user supports having gripping handles mounted on pivotable levers that move in an arcing motion relative to a forward and central portion of the movable user support frame. A linkage assembly operatively connects and synchronizes the exercise motions of the upper and lower body user support assemblies. In certain embodiments, an adjustable resistance mechanism is operatively engaged with the upper and lower body user supports for providing adjustable resistance to the exercise motion of the upper and lower body user supports.

An exercise machine assembly provides a fluid-based resistance force and allows a user to exert a force against the resistance force. A fluid displacement device is coupled to the exercise machine assembly and rotatably driven by the force exerted by the user. A fluid container has a hollow body enclosing the fluid displacement device, allowing for the fluid displacement device to rotate therein, and encloses a fluid. The fluid container includes an inner reservoir and an outer reservoir that cause the fluid-based resistance force to vary based on amounts of fluid in the inner and outer reservoirs, respectively. Further, the inner reservoir has one or more openings through which fluid can flow from either of the inner reservoir or the outer reservoir to the other.

The present disclosure discloses a device and a method for converting reciprocating motion into continuous rotation, and application includes: a central shaft and rotating discs, each rotating disc is connected to the central shaft through a bearing, the rotating disc is arranged concentrically with the bearing, wings are arranged on a circumference of rotating disc, upper wing surfaces of the wings are of convex structures. According to the device for converting reciprocating motion into continuous rotation of the present disclosure, the rotating directions of the wings can be kept unchanged all the time during the reciprocating motion of the device by using airfoil structures of the wings in the device and limiting mounting angles of the wings, so as to obtain a continuous lifting force with a constant direction.

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.
