The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

A wheel spinning exercise system for providing an effective exercise and therapeutic tool useful for releasing carpal tunnel syndrome, strengthening muscles of hands, relieving arthritis, and providing relaxation to an exercise-user. A central disk having a first-aperture, a first-middle-aperture, a second-middle-aperture, and a third-aperture. The device further includes at least one first-cord which passes through the apertures.

Handle grip are configured to interface to the end of a bar allowing a user to employ the bar for motion, exercise, stretching or other activity. For example, the handle grips may slip onto the bar under force. The handle grips include a grip section, configured to provide a surface the user can grab. Accordingly, the grip surface may include features that increase the effective friction coefficient. The handle grip also includes an end section configured to react both axial and lateral loads applied by the user via the grip section. The bar can be sectioned, making storage and transport easier. Accordingly, the sectioned bar can be assembly to provide the desired length of exercise bar.

A grip interface is used to provide information about a user to a range of connected devices and applications based on the users' interactions with the grip. By embedding into the grip an array of sensors for motion, health, environmental and other data using embedded microcontroller network technology, and focusing on the grip as the interface between the physical and virtual worlds, applications and services to existing grip-based devices are enabled. Applications for the grip include as sports, fitness equipment, health monitoring, activity tracking, coaching, physical therapy, mobility aide and virtual entertainment, among others.

A hand strength appliance is provided that may be used in multiple or selected configurations for grip and pinch strength assessment as well as grip and pinch exercises. The appliance includes a frame and a sliding internal handle fitted within and slidable within the frame, and may be positioned for multiple test positions and exercises. The appliance may include and be used with a force sensing device that may transmit information to a computing device.

A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.

A resistive therapeutic device is disclosed such that upon a user applying torque a controller emits a signal to an electromagnetic resistance generating member. The controller detects a maximum torque applied by a user detects if the maximum torque applied by a user is less than or equal to a resistance setting. The torque resistance is variable from a neutral position to a maximum position, and the controller increases the resistance setting as a user moves a torque application member in a direction away from the neutral position that represents an increase in torque applied by the user. A control and user interface for a resistive therapeutic device includes an evaluation display of torque strength applied and displays an angle of rotation clockwise or counterclockwise directions ranging from 0 degrees to 360 degrees and a count of repetitive times a user has rotated at least 360 degrees in either direction.

A compression-resistant device includes least one pair of first and second opposing jaw members having respective engaging surfaces for movement from an open position receiving an object and a closed position engaging the object. A manual compression surface enables a user to manually apply pressure to urge the engaging surfaces from one of the closed position towards an open position or from the open position towards the closed position. At least one resistance member interfaces with the first and second opposing jaw members to resist pressure manually applied by a user urging the engaging surfaces from the closed position towards the open position or from the open position towards the closed position. The manual compression surface includes projections such that manually applied pressure forms at least one aggravated area on a finger surface of the user to initiate a callus. A corresponding method of operating the device is also disclosed.
