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.

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.

Embodiments of golf coupling mechanisms for joining golf club heads and shafts are described herein. The golf coupling mechanism allows for adjustment of a club head loft angle, a club head lie angle, and a golf club shaft length while utilizing one club head and one shaft. In a fully extended configuration, the golf coupling mechanism includes a shaft sleeve, a removable spacer, and a removable extender, wherein a fastening assembly secures the golf coupling mechanism to the golf club head. In a contracted configuration, the golf coupling mechanism includes the shaft sleeve. The golf coupling mechanism further includes a shaft cap to soften the interaction between the shaft and the golf coupling mechanism. The golf coupling mechanism further comprises one or more arcuate coupler sets to frictionally lock the shaft relative to the golf club head.

Disclosed is a golf putter for bidirectional golf putting. The golf putter comprises a putter head, a putter body and handles connected to one end of the putter body, wherein the putter head comprises a golf putting portion and a connecting portion; the connecting portion fixes the golf putting portion onto the other end of the putter body opposite to the handles; the golf putting portion is provided with a first golf putting surface and a second golf putting surface; and the first golf putting surface and the second golf putting surface are symmetrically disposed with respect to a plane where a center axis of the putter body and a center axis of the golf putting portion are located. The golf putter provided by the present disclosure is provided with the two golf putting surfaces symmetrically disposed at the putter head, and can thus realize bidirectional golf putting.
