The SKLZ Gold Flex golf swing trainer is designed to improve swing tempo, strength, and flexibility. The exaggerated flex in the shaft helps lengthen your swing by keeping your hands and arms extended. This creates power to help you bomb your drive and gain more distance. The extra flex also encourages a slight lag at the top of your back swing, establishing the ideal swing tempo. The momentum the weighted head creates when swinging through encourages proper weight transfer and a full follow through for form, balance, and power. SKLZ Gold Flex Trainer
