You can also acquire an ideal swing. ・Because it has weight, you naturally swing using your body. It is said that you won't feel the weight when you acquire a natural and correct swing.

Find your swing habits. ・Swinging a heavy club strengthens the grip and wrist, and not only naturally memorizes the correct weight transfer, footwork, hip rotation, and rhythm, which are important in the swing, but also has the effect of correcting or preventing your bad habits, as Gene Sarazen also said. ・The slow-motion swing of swinging a heavy club slowly has the effect of training golf muscles and imprinting the correct club position in the brain. I remember reading an article that Ai Miyazato also performed Tai Chi swings (slow-motion swings) during her active career. ～※～※～※～※～※～※～※～※～※～※ Golf-related items are also on sale ～※～※～※～※～※～※～※～※～※～※ #domtropen144 ← You can see the list of items for sale.
