A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

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 portable golf swing exerciser includes: a main body of a shaft shape; a head shaft including a head, and one or more connection shafts, of which one end is detachably coupled to the head, and the other end is detachably coupled to a front end of the main body; and an antenna stick guide extended from or retracted into a rear end of the main body in a form of an antenna having multiple sections.

A collapsible juggling club is disclosed herein. The collapsible juggling club can include an end portion, a plurality of intermediate portions, and a handle portion. The end portion defines a cavity and includes a first diameter. The handle portion includes a second diameter that is less than the first diameter of the end portion. The plurality of intermediate portions include descending diameters and are arranged telescopically between the end portion and the handle portion, such that the juggling club can telescopically transition between a collapsed condition, wherein each intermediate portion of the plurality is nested with the cavity defined by the end portion, and an extended condition, wherein the end portion, each intermediate portion of the plurality, and the handle portion are secured to an adjacent portion via a friction fit.

A pocket-sized, retractable golf club stand that can hold one or more golf clubs is described. The golf club stand includes a magnetic club holder that is attached to a telescoping shaft which is attached to a base including a slidable anchor. During use the anchor is extended and embedded into the ground, the telescoping pole is extended, and clubs are held against the device by the magnetic holder. Upon completion of use, the clubs are removed from the magnetic holder, the telescoping pole is retracted, and the anchor is slidably hidden away. In addition to holding golf clubs the device's anchor may be used for divot repair and the magnetic club holder may be used to secure ball markers.

A golf accessory for determining a gimme putt distance is disclosed. The golf accessory comprises a handle with a trigger, a telescoping rod mounted to the trigger including a length adjustment configuration, a hinge mechanism mounted to the telescoping rod and a base mounted to the hinge mechanism. The hinge mechanism is configured to allow the telescoping rod to fall horizontally on a ground surface upon activation of the trigger to determine a gimme distance in a golf game. The gimme is determined as positive if the telescoping rod covers a ball marker on the ground surface. The gimme is determined as negative if the telescoping rod fails to cover a ball marker on the ground surface.
