Golf Practice Equipment Swing Training Swing Practice 100cm Orange 【Strength Training with More Than Double the Weight of a Club】 Although shorter than the average driver, it weighs over 550g, more than double. You can expect to build more muscle than swinging a typical driver. You can simultaneously train the "biceps" and "triceps," the muscles needed for swing speed. 【Core Strengthening to Avoid Being Thrown Around】 Strengthening the core allows for a stable swing. The golf swing trainer has weight, so you'll feel the sensation of being "thrown around." Your core will be strengthened in the process of training the feeling of "being swung" to "swinging." 【Learn the Flex for Maximum Distance】 You can learn the feeling of "flex" needed for increased distance. By training while imagining the transition from the swing change to impact, you can learn to use your whole body in a large motion. 【Effective Warm-up】 Also recommended for stretching and warming up before practice. Because of the weight, it's perfect for loosening up your body. Just a few practice swings will stretch your muscles just right and warm up your body. Please use it before your round. 【Size】 Total Length: Approx. 100cm / Head: 7cm x 7cm 【Weight】 Approx. 550g 【Material】 Head: PVC / Shaft: ERP / Handle: Non-slip handle 【Shipping】 Shipping to Hokkaido/Okinawa/remote islands will incur an additional charge of 800 yen.
