A spherical hand exerciser has a resilient, non-slip exterior with an off-center cavity and a weighted core housed within the cavity. A method of performing physical therapy with the exerciser includes grasping at least one exerciser; and manipulating it around the hand and fingers. The offset placement of the weighted core works stabilizer muscles of the fingers, hand, wrist, and forearm during manipulation, increasing the synergy and workable range of motion of both the flexor and the extensor muscles, allowing for faster learning and better effects.

An apparatus or system defined by a handheld exercise device includes a weighted body; a handle arranged along a radial axis of the weighted body; and a connector that creates at least one connection between each radially distal end of the handle and a component of the weighted body. The handheld exercise device, in use, minimizes one or more peak forces and rotational inertia acting on a forearm of a user actively engaging the handheld exercise device in motion.

A handheld exercise device is an apparatus that enables the user to exercise the upper body due to the load applied on the user's arms from the centripetal force created by moving the apparatus using one or two hands. To do so, the apparatus may include an O-ring housing, a crossbar, a bearing assembly, and a control system. The O-ring housing is designed to retain the bearing assembly in such a way that the user can move the bearing assembly in a circular motion within the O-ring housing. The crossbar facilitates the handling of the O-ring housing with one or two hands in order for the user to move the bearing assembly in a circular motion within the O-ring housing. The control system helps the user keep track of the movement of the bearing assembly so that the user can measure the exercise progress while handling the apparatus.

An apparatus, kit, and method for rehabilitating and/or strengthening the soft tissues of a user's lower arm is disclosed. The apparatus has a first arm with a proximal end and a distal end; a second arm with a proximal end, a distal end, one or more discrete sections therebetween for engaging one or more weights, and a means for providing an audible feedback to the user upon completion of an exercise repetition or a half-repetition; and a hinge in contact with the proximal ends of the first and second arms. The hinge is configured to adjust the distance between the distal ends of the first and second arms, or the angle separating the first and second arms.

The present invention may be embodied as a system or method for dynamically exercising a user's neck muscles. The system includes a headset, an arm attached thereto, a weight, and at least one motor to move the weight, for example, about the arm. The weight may be mounted eccentrically on a radial track that is rotatable by one motor and moved linearly by another motor. The direction of the arm, the distance between an apex of the headset and the weight, the eccentricity of the weight on the axis, and the speed of rotation of the motor are all parameters that can be adjusted by the caregiver or user, either manually or via controlling software.

A weighted fitness hoop apparatus for cardiovascular and resistance exercise. The hoop comprises an elliptical tubular sheath with two end portions, the ends selectively engageable by a coupler. A hollow core extends through the length of the tubular sheath and is optionally fillable with a weight or light. The coupler is insertably engaged with the hollow core at the first and second ends of the elliptical tubular sheath, and the power source for the light is removably attached to surface of the hoop.

Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

A fitness and rehabilitation aid is provided, using mostly centrifugal forces that are taking the body centre of mass from its natural position where the mutual configuration of the individual components, that create the aid, optimally stimulate the desired muscle parts. The aid consists of a loading head for achieving the desired centrifugal force and a handle for grasping by the user. The loading head and handle are interconnected by a flexible connecting component. A length of the flexible connecting component from the point where the flexible connecting component leaves the handle to the point where the connection of flexible connecting component and loading head occurs, i.e. the hole for entering of the connecting component to the loading head, equals at least 600 mm.

A hand-held centripetal exercise devices are shown and disclosed. In one embodiment, the device includes an outer shell having a smooth outer surface. The outer shell defines an internal volume. The device additionally includes a single ball sized to be contained within the internal volume. The single ball having a predetermined mass.
