A counterweighted golf club training apparatus providing a counterweight element affixed to a shaft protrusion, or portion of the hollow shaft's proximal end protruding through the second end of the grip handle, wherein the center of balance of the apparatus is positioned at a space between the user's hand, thereby redistributing the weight and allowing equal forces to be exerted on each hand without the need for the user to account for swingweight or gravitational effects. Thus, the user is able to swing and practice their movements freely without any individual motion dictating the composition of the overall swing. This apparatus will increase the capability of any user to improve their swing mechanics, train their muscle memory, and confidently advance their ability to correctly swing a club without needing to worry about making mistakes.

A golf club comprises: a pipe-shaped shaft having a space therein and having a first end and a second end; a weight member attached to the shaft on a first end side; and a golf club head attached to the shaft on a second end side. The weight member comprises: a main body portion at least partially disposed in the space of the pipe-shaped shaft; and a flange portion disposed outside the pipe-shaped shaft. The flange portion comprises: a first portion extending in the radial direction of the shaft and having an outer diameter larger than an outer diameter of the shaft at the first end; and a second portion extending in the axial direction of the shaft from the first portion toward the second end so as to cover an outer circumferential surface of the shaft.

This invention relates generally to a muscle activating and exercising device and a method of activating and exercising muscles of the human body. More particularly, it relates to an elongated device that is pliable enough to be wrapped around an object. Such 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 rack). The present invention also relates to a method of activating muscles using a pliable device. Through such a method, a user can, for example. build muscle strength and/or reduce muscle tremors.

A sports training device which allows for easy interchanging of weighted inserts. The sports training device includes a body, a handle, a contact zone, a inner chamber, a capping mechanism, and a weighted insert. The weighted insert attaches to the capping mechanism which can be attached the body of the device. The weighted insert is enclosed by the body within the inner chamber. The contact zone of the device can be equipment such as a baseball bat, softball bat, tennis racket, hockey stick, cricket stick, or any equipment used to strike a ball.

A somatosensor device comprises a handle (10) having a hollow free end (130) to form a cavity (133) with an opening in a tail end surface (131); a wireless charging circuit board (30) overlapped on the tail end surface (131); a tracker (50) fixed on the wireless charging circuit board (30) and electrically connected with same, the tracker (50) inserted into the cavity (133) as the wireless charging circuit board (30) is overlapped on the tail end surface (131); and an end cap (70) covered on the free end (130) of the handle(10), so as to seal the cavity (133) with the opening in the tail end surface (131). The configuration takes account of the sealability and wireless charging.

A golf club with improved weighting characteristic is disclosed. More specifically, the present invention discloses to a golf club wherein the improved weighting distribution stems from an increase in the mass of the golf club at a specific distance away from the butt end or proximal end of the golf club head to help increase the feel and minimize the dispersion of the golf shot by minimizing the pull and or draw tendencies of a golf shot.
