If you have trouble snapping your wrist to create spin on your serve, you might be gripping your racquet too tightly. To serve effectively, you must relax your hand and keep your arm loose. Serving with three fingers can teach you the benefits of a relaxed grip. Line up to serve and drop your pinky and ring finger off the racquet handle. Don’t worry whether you can serve hard or even get the ball over the net. With this grip, you’ll see that your racquet drops down naturally and snaps through the ball. Once you understand what it feels like to serve without tension, return to your regular, though now more relaxed, grip.
