Description

In the present invention, for the purpose of training the fast muscles for increasing the flight distance, the weight is reduced to about half that of a conventional golf club, and the swinging comfort is not uncomfortable with a golf club that is usually used. It is a golf practice device that enables adjustment of the distance of the center of gravity, the depth of the center of gravity, and the angle of the center of gravity so that it swings.

Conventionally, practice equipment for swinging in golf is often heavy at 500 g to 900 g, and is intended to train muscle strength (slow muscle) for power-up, and is heavy at 500 g to 900 g to increase swing speed. There was no choice but to shake the practice equipment for swinging in the opposite direction, or to shake a rod-shaped object.

For example, in Patent Document 1, a golf swing practice device in which one side grip is provided on one end side of a shaft and the other side grip is provided on the other end side, and the grip includes one side grip and the grip is provided. When the provided part is a one-sided grip, the other-sided grip is included, and the part where the grip is provided is the other-sided grip, the one-sided grip is adjusted to be heavier than the other-sided grip. The frequency when one side grip is vibrated with the other side grip part fixed is "F1 (cpm"), and the frequency when the other side grip is vibrated with the one side grip part fixed is "F1 (cpm"). A golf swing practice device characterized in that it is adjusted so that "F1 <F2" and "F1 = 90 cpm to 220 cpm" when "F2 (cpm)" is set is disclosed.

If the golf swing practice device described in Patent Document 1 is used, when the golf swing practice device is used with the other side grip as the tip and the one side grip is gripped and swung, the tip is light, so that the tip feels almost no weight and the speed is high. It is said that you can make a swing with a feeling.
