How to Increase Club Head Speed
To improve your club head speed, hold the club at a 45-degree angle in front of you with your feet shoulder-width apart and your knees slightly bent. As you swing the club back, bend your wrists and turn your shoulders so your back is facing your target. Then, turn your hips to the left and pivot on your right foot to create extra power as you swing the club. Additionally, keep your wrists bent as you hit the ball, which will give your swing more power.
