Provided is a golf shaft, capable of ensuring bending rigidity required for a golf club and providing good hit feeling in a composite shaft with 50 g-130 g. The golf shaft comprises an element tube made of metal, an outer layer made of a fiber reinforced plastic and covering an outer periphery of the element tube over an entire length of the element tube in an axial direction, an adhesive layer interposed between the element tube and the outer layer to bond between the element tube and the outer layer, wherein weight of a whole including the element tube, the outer layer, and the adhesive layer is 50 g-130 g, and weight of the element tube is 50%-90% of the weight of the whole.

A multi-material golf shaft having a butt portion joined to a tip portion and possessing unique relationships, including rigidity relationships, which provide beneficial performance characteristics.

A process for manufacturing a putter with a bi-material shaft is disclosed herein. The putter comprises a putter head, the bi-material shaft, a mass member and a grip. The bi-material shaft comprises a body with a tip end and a butt end. The body comprises a metal section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point. The mass member is positioned within an opening at the butt end of the shaft. Mass from the shaft is transferred to the club head and the mass member in the butt end of the shaft.

Described herein is a method of using a game stick that involves positioning a golf ball within a channel in the game stick's head, which has sidewalls and a bottom wall. The player swings the stick to propel the ball toward a target, advancing and repeating until reaching a designated putting area. A striking surface is then attached to the sidewall using a magnet. The player aligns the striking surface with the ball and applies a putting stroke to direct the ball toward the hole.

A sheath for protecting an athletic equipment shaft is formed from a heat shrink material. The sheath is contemplated as capable of having a directional shrink in the transverse direction greater than 50% allowing the sheath to pass over additional components on the shaft, such as a golf club grip, while still being able to constrict down to effectively compress and secure to the shaft. The sleeve is formed from a material that allows for the inspection of the underlying shaft and allows for a printed indicia on an interior surface, wherein the printed indicia is also protected, to be visible through the sleeve. A longitudinal perforation is also contemplated in an example to aid in the removal of the sleeve without damaging the underlying shaft.

A swing motion trainer used to simulate one or more sport swing movements includes a rod portion comprising a shaft with a grip. The swing motion trainer includes a resistance portion comprising an interchangeable mechanism at a distal end of the rod portion, the resistance portion includes an interchangeable mechanism at the distal end of the rod portion, wherein the interchangeable mechanism is configured to attach a removable resistance element to the distal end of the rod portion. The removable resistance element that is attachable to the distal end of the rod portion via the interchangeable mechanism. The removable resistance element provides a resistance to a swinging motion of the swing motion trainer.
