An arm strengthening device comprises a telescoping rod having a plurality of ergonomic grips at a first end and a removable circular weight perpendicularly disposed at a second end.

A hand exerciser to strengthen and promote flexibility for both extension and flexion for the fingers, thumb and hand has a body defined by a resiliently deformable first outer ring and a resiliently deformable second inner ring that is concentric with the first outer ring. Flexion exercises utilize the first outer ring while extension exercises utilize the second inner ring.

Presented is an Isokinetic exercise system having a base, a pedestal, a vertical member, a height adjustable vertical column for resting a rotary actuator on top, a resistance control valve unit with rotatable dials connected to the actuator, wherein the rotatable dials are selectively used to rotatably set a range of resistances for opposing movements to accommodate varying exerted forces by a user performing an intended exercise. The system further includes an electronics module to detect angle and pressure related data (as a measure of voltages) associated with the actuator, an A to D converter to convert the detected voltages in a digital form, a display unit embodying a program product for receiving, and processing the detected voltages to generate and display a muscular performance assessment report, store the received voltages for future comparison and enable printing the muscular performance assessment report, enable configuring next intended exercise.

A method is provided. The method comprises a first step of acquiring wrist exercise information including at least one of orientation information and motion information of a wrist of a user, a second step of acquiring upper body exercise information including at least one of orientation information and motion information of a torso of the user, a third step of calculating, using reference wrist exercise information and reference upper body exercise information corresponding to each of a plurality of exercise types, a first similarity degree between the reference wrist exercise information and the wrist exercise information and a second similarity degree between the reference upper body exercise information and the upper body exercise information for each of the exercise types, and a fourth step of determining an actual exercise type performed by the user, among the exercise types, based on the first similarity degree and the second similarity degree.

A rotation mechanism of a wrist exerciser is provided. The rotation mechanism includes a sleeve ring, a spinning mass, and a driving assembly. The sleeve ring is rotatable along an annular groove. The sleeve ring includes an annular body and a mount component. The annular body has a first mount portion and a first insertion hole respectively located at two opposite sides of the annular body. The mount component has a second mount portion and a second insertion hole. The second mount portion of the mount component is engaged with the first mount portion. Two shaft portions of the spinning mass are respectively and rotatably located in the first insertion hole and the second insertion hole, allowing the spinning mass to be rotatable. The driving assembly includes a stator fixed to the mount component and a rotor mounted on the spinning mass.

A method for treating pronator syndrome involves selecting an arm and positioning it with the forearm perpendicular to the upper arm. The hand of the arm is engaged with a grip located inside a bisected working circle, which has an outer perimeter consisting of four quadrants. The fourth quadrant is elliptical and asymmetrical to the others. The grip is designed for hand engagement and includes two d-shaped slots. A resistance band is attached to the body, with one end in the groove, creating tension when used. To exercise the arm, the body is rotated in one direction to increase tension on the band. Releasing tension is achieved by rotating the body in the opposite direction.

An exercise and rehabilitation bar including a flexing bar, at least one resistance insert, and at least one handle. The flexing bar has a first end, a second end, and a cavity running from the first end to the second end. The at least one resistance insert is removably carried within the cavity of the flexing bar and the at least one handle is removably securable to either the first or second end of the flexing bar.
