The present invention discloses a swing training device for enabling a user to learn a proper swing. The swing training device comprising a barrel, a handle having a first handle portion and a second handle portion and an extender device coupling the first handle portion and the second handle portion. The swing training device is configured to enable a user to achieve proper swing mechanics through feedback or diagnosis and correction of an individual user's swing. The swing training device further configured enable the user to establish muscle memory in the correct batting position so that the user would be able to assume the proper position and execute the swing consistently with proper swing mechanics.

A golf club length adjustment device, comprising a first member affixed to a main shaft, the main shaft configured to couple to a golf club head, a second member slideably coupled to the first member, the second member adapted to couple to a golf club grip, wherein the first member is configured to slide along a club axis relative to the second member to change the length of the golf club.

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 multiple purpose tool assembly for attaching a variety of implements to a handle includes a handle and a rod that is removably coupled to the handle. The rod has a first portion that is slidably coupled to a second portion such that the rod has a telescopically adjustable length. A lock is removably coupled to the second section of the rod. The lock is biased into a locking position for retaining the rod at a selected length. Additionally, the lock is urgeable into an unlocked position thereby facilitating the length of the rod to be adjusted. A plurality of attachments is each selectively and removably attached to the rod for performing specific tasks.

A golf swing exercise machine allows a player to develop their golf swing by forcing the head of an adapted golf club to follow a preferred wing path. The path is marked by a rail. The rail is held by a rail support that is oriented with respect to the ground by a frame. The frame is made up of a base with side, front and back support members and horizontal supports. The golf club head has slots to allow the head to follow the rail.
