Provided is a handheld dexterity training technology. In one example a handheld dexterity training device comprises two portions that are rotatable relative to one another about the axis of rotation of a twisting joint that connects them together. One portion comprises a handle while the other portion comprises a panel having a playing surface that can be used to strike a ball to make it bounce. A stopper prevents rotation beyond a certain angular range. The rotatability of the handle relative to the playing surface poses a particular challenge. A releasable lock can bind the two portions together. Other features and components are possible. A method of dexterity training is also provided.

A shoulder motion exercise device and method of use having a retainer, a connector, an extender, and a slider. When the user mimics a golf swing, the device aids in the stretching and exercise of at least a shoulder and a portion of the torso.

A sporting-good implement, such as a ball bat or a lacrosse stick, includes a first handle section rotatably connected to a second handle section. The second handle section may be attached to or integral with a tapered region or barrel region of a ball bat, or with a shaft section or head of a lacrosse stick, or with another sporting-good feature. This rotatable engagement allows the relative position of the user's hands to change during the course of a swing, shot, or pass, ideally placing the user's hands in a position to generate improved power or control.

A shoulder motion exercise device and method of use having a retainer, a connector, an extender, and a slider. The extender is gripped in one hand, the slider, which is in slidable engagement with the extender, is held in the other, and the slider is attached to the retainer at, or above, the elbow of an intended user. When the user mimics a golf swing, the device aids in the stretching and exercise of at least a shoulder and a portion of the torso.

A golf putter grip accessory includes a protruding grip body and a clamping assembly. The grip body includes an inner surface designed to face a golf putter grip when the golf putter grip accessory is removably attached to a golf putter, and an outer surface that is ergonomically contoured to provide a gripping surface for an extended index finger of a user to assist a user in holding the golf putter straight. The clamping assembly is attached to the grip body and designed to releasably attach the golf putter grip accessory to the golf putter.
