A rotation exercising ball structure includes two shells, two pivot seats, two holding members, a weight unit, a first housing, a second housing, and a PCB (printed circuit board). The two shells are combined together to construct a hollow ball. The weight unit includes a mandrel pivotally connected with the hollow ball, two magnets secured to the mandrel, at least one rotation member connected with the mandrel, and a weight connected with the at least one rotation member. The PCB is electrically connected with a Bluetooth transmission device which is electrically connected with a Hall sensor. When the mandrel is rotated, the Hall sensor detects rotation of the magnets and sends information of rotation of the magnets to the PCB, and the PCB processes and transmits the information to the Bluetooth transmission device.

The present invention relates to a training device (10) for training the arm muscles and muscle groups associated therewith, comprising: at least one flywheel mass member carrier (1) with at least one flywheel mass member guide (1a) for guiding at least one flywheel mass member (2) along at least one elliptical path deviating from a circular shape or at least one elliptical path segment, wherein the flywheel mass member guide (1a) forms a guide of the at least one flywheel mass member (2) extending beyond a semi-ellipse and spans a flywheel mass member guide plane (y, z) in the radial direction of the elliptical path or the elliptical path segment, and at least one handle member (6) with a handle axis (6a) to be encompassed for gripping, wherein the handle member (6) is arranged in the handle axis (6a) at least sectionally in a handle plane (6b) which extends perpendicular to the flywheel mass member guide plane (y, z) and which does not intersect the elliptical path or the elliptical path segment.

An apparatus and method may exercise muscles of a body part, especially the neck, waist, torso, legs, and glutes from any angle with variable resistance while taking up minimal floor space. The apparatus may improve the ability of athletes, including football players and wrestlers, to better prepare for contact from any angle while engaged in their sport. The apparatus may include a ring having a guide track therein. Another inner ring may also be provided in different sizes and shapes to accommodate a variety of users. A car may be connected to a source of resistance ride freely along the guide track. The source of resistance may be other gym equipment including a bungee cord, a cable cross over machine, springs, and the like. As the user freely exercises by moving the body part, the car may adapt to the user's position to facilitate a full range of motion.

The disclosed apparatus, systems and methods relate to a bi-bell exercise device for low-impact exercises. The bi-bell can be used in place of a kettle bell, and has two handles and a selectively rotatable weight. The bi-bell can be used in a fixed configuration, where the weight does not move relative to the handles, or a rotating configuration, where the weight is free to rotate relative to a central post.

A multi-purpose home workout device. The device comprises a resistive weight with an open channel designed to allow an axle to pass therethrough, such that the axle is operably connected to a wheel, and an outer frame. The outer frame further includes a pair of bracer arms designed to receive the axle and to redistribute the weight of a user across the outer frame. The wheel includes an open interior space and is positioned between the bracer arms such that the resistive weight can rest on the axle within the interior space. Furthermore, the orientation of the wheel and the outer frame allow both to rotate about the axle without interfering with one another's movement. As such the outer frame is predisposed to tilting at non-horizontal angles when in use, and thereby forces a user to train their balance, strength and coordination simultaneously.

A weighted stretching and strengthening device for exercise. This invention encourages a proper conditioning of the body's muscles and joints before playing in any sport that requires a swinging motion. This device enables the player to establish end range movements in the upper body, increases stamina to enhance a players striking ability, and, in turn, could help reduce injuries. This invention provides the player with a universal warm up and strengthening device that is durable, safe and easy to use.

A combination loadable dumbbell and bumper weight including a loadable dumbbell having a central shaft and opposing sleeves. At least one bumper weight having a core and a bumper portion surrounding the core is provided. The core has a central bore. The at least one bumper weight can be slid over one of the opposing sleeves so that the opposing sleeve is directed into the central bore.

The methods as described herein relate to methods with a hollow hoop with a ball enclosed inside, where the methods keep the ball moving in a circumferential path while the body is in various positions and movement paths for uses in entertainment, training, and therapy.

The present disclosure relates to a hula hoop. The hula hoop includes a track assembly with a plurality of track units interconnected end-to-end and a slider provided with rollers. The track unit includes an outer track having a receiving channel located at a first end and a protruding portion located at a second end opposite to the first end, a pressing component configured to secure two adjacent track units, and an inner track for jointly defining a circular path with the outer track. The rollers of the slider are configured to slide along the circular path. The hula hoop of the present disclosure is easy to assemble and disassemble.
