The present invention relates to a golf club for practicing swings which enables learning a smooth rhythmic sensation under the concept of hitting a ball with a sphere having a metal texture, so as to maintain a stable swing track involving proper rhythm in real swings to correctly send a ball to a desired position. The golf club for practicing swings comprises: a shaft provided with a handle at the top end; and a head coupled to the bottom end of the shaft, wherein the sphere providing a metallic material sensation is integrally formed with the face of the head or detachably formed on the head, thereby providing an image of softly hitting a ball with the sphere made from the metallic material during practice swings.

A training weight for a sport stick is provided. The sport stick includes a housing having a sidewall, a proximal end wall and a distal end wall. The sidewall and proximal end wall include an opening and slot which are sized to accept a sport stick's handle and knob. Preferably, the training weight includes a cup which is biased by a spring to force the sport stick's knob to engage and lock to the training weight's proximal end wall. The training weight may include a cam mechanism to permit the retraction and extension of the spring and cup.

A golf practice device is disclosed to derive a proper stance and swing form of a golf club. The device to be installed on a shaft of a golf club with a club head, comprises a fixing part to be installed on the shaft and including a bearing part formed at a part thereof, and a shaft part to be fitted in the bearing part. In a state where a longitudinal direction of the shaft is horizontalized and a toe side of the club head is located on a ground side, the fixing part is installed at a center of gravity position of the entire golf club, on the shaft, and one end in an opposite side of the bearing part in the longitudinal direction, of the shaft part faces a vertical direction with respect to the longitudinal direction of the shaft to point a core of the golf club.

A golf training aid 20 that provides to the user unmistakable positive feedback how to use the hands, wrists and forearms in the golf swing to affect what has been popularly called Ben Hogan's Secret Move, particularly during the transition of the golf swing. Golf training aid 20 also provides the golfer unmistakable feedback as to whether they have executed the correct movement that Hogan explained in his 1955 Life magazine article.

Provided is a weight pattern determination apparatus for determining, in a golf club having a head capable of mounting one or more weights in a plurality of mounting patterns, the mounting pattern suited to a golfer. The apparatus has an impact point specification unit and a pattern determination unit. The impact point specification unit specifies an impact point distribution of the golfer. The pattern determination unit determines a recommended pattern which is the mounting pattern that approximates a sweet area of the golf club to the impact point distribution. According to the first aspect of the present invention, the impact point distribution of the golfer is specified, and a mounting pattern is determined based on this impact point distribution.

A muscle activating and exercising device and a method of activating and exercising muscles of the human body. The device includes an outer material and at least one flexible inner material. The device is an elongated device that is pliable enough to be wrapped around an object. The device also has an outer surface that creates a frictional fit between the device and the wrapped object. The wrapped object could be, for example, a wrist or ankle on a human limb or a location on a portion of sports equipment (e.g., a lacrosse stick, baseball bat, hockey stick, golf club or tennis racket). The method includes a method of activating muscles using the device. Through such a method, a user can, for example, build muscle strength and/or reduce muscle tremors.

Ball striking devices, such as golf clubs, have a head that includes a face member including a face having a striking surface configured for striking a ball and a rear side located behind the face, a rear member connected to the rear side of the face member, a first connection member connecting the face member to the rear member, and a resilient material separating the rear member from the face member. The first connection member is directly engaged with the rear member, and the club head further includes a first spacer separating the first connection member from the face member. The first spacer is flexible, and the first connection member indirectly engages the face member by compressing the first spacer against the face member. The resilient material engages the rear member and the face member and is configured to transfer momentum between the face member and the rear member.
