Abstract: A golf swing resistance device that secures to a golf club to provide increased aerodynamic drag during a golf swing. The device includes disk-shaped plates with a through-bore in the center of the plates. The plates are secured to the golf club by passing the grip end of the golf club through the through-bore of the plates. The plates align along the golf shaft of the golf club and abut against the golf club clubhead during a golf swing. Multiple plates can be stacked along the length of the golf shaft. The plates have a larger span (or diameter) than the golf shaft thereby increasing the cross-sectional area of the golf club and thus increasing the aerodynamic drag on the golf club during a golf swing. The plates can vary in size and quantity to provide variable amounts of aerodynamic drag.

Abstract: A connector forms a releasable connection of a golf club shaft and a golf club head. The connector includes a shaft-mount and a head-mount. The shaft-mount has a first threaded coupling member and a bore that is sized to securely receive the golf club shaft. The head-mount has a second threaded coupling member. The head-mount is sized to be securely received within the bore of the hosel of the golf club head. The first threaded coupling member of the shaft-mount mates with the second threaded coupling member of the head-mount to form a releasable connection of the golf club shaft and the golf club head. The first threaded coupling member of the shaft-mount has dual-handed-thread ability which allows the releasable connection to follow left-handed-thread convention and right-hand-thread convention.
