Elite Grips Swing Training Device One Speed / 1SPEED The item for sale is the orange type. One Speed is a training device that allows you to feel the flex when swinging the heavier side and experience the head's speed on the opposite side. To improve your golf game, the key is to master swing reproducibility and swinging with your whole body through daily practice swings. Daily practice swings during the off-season in winter will lead to significant improvement. The actual product has been cut by 1 inch on the heavier side (weight side). I cut it by 1 inch to prevent excessive flex in my practice swing. Original length: 46 inches ➡ Current length: 45 inches. This is a training device that enhances the value of daily practice swings. Pro Kuramoto was in the commercial. The lesson DVD is missing, unfortunately. Thank you for your understanding. Please consider purchasing.
