If you are trying to get more power on your serve, you need to stop trying to hit the ball harder. Swinging harder often creates tension, which actually limits your power. The real key to a stronger serve, according to coach Austin Hardy, is learning how to create lag.

Lag allows you to generate effortless power by keeping your arm relaxed and whipping through the ball at contact. Instead of forcing the shot, you are letting the paddle accelerate naturally, which produces more speed and spin.

The first step in developing lag is to build the feel of the motion. A simple drill at the net can help with this. Stand close to the net and point the butt cap of your paddle toward the side fence. From there, bring the paddle forward and repeat that motion over and over again. This teaches you how to position the paddle correctly before accelerating through the ball.

Many players struggle with power because they “push” or guide the ball instead of swinging through it. The goal is to feel like you are slapping through the ball with a relaxed arm rather than patting it.

Next, you should focus on your stance. Too many players keep their front foot completely closed, which prevents proper rotation. Instead, your front foot should be slightly open so your hips and shoulders can rotate through the shot. This rotation is essential for generating both power and control.

As you progress, you can build on the drill by adding a windshield wiper motion. Start farther away from the net and reach forward. From this position, your paddle should move from behind you to out in front of your body in a smooth, upward motion. Your wrist should go from being loaded to relaxed at contact, which helps create both spin and pace.

Once you are comfortable with the motion, move back to the baseline and rehearse the full swing without a ball. Focus on transferring your weight from your back leg to your front leg as you swing. Your motion should stay relaxed and fluid, and your swing path should follow the line of the net.

When you are ready to add the ball, avoid tossing it. Instead, hold the ball in your hand and release it as your wrist relaxes into the swing. This will help you maintain better timing and consistency.

It is also important to understand where your power comes from. Power does not come from your arm alone. It starts from the ground and travels upward through your body. Your legs play a critical role in this process. As you load and push off the ground, that energy transfers through your body and into your swing.

If you try to generate power only with your arm, you will become tense and lose the ability to create lag. Staying relaxed allows the energy from your legs to flow naturally into the paddle.

After you make contact, your momentum should carry you into the court. Stepping forward helps you complete your rotation and maximize power. More advanced players even add a small forward jump after contact to increase momentum and energy transfer.

In the end, improving your serve is not about swinging harder. It is about using the right sequence of movements. By creating lag, staying relaxed, using your legs, and practicing these drills consistently, you can develop a more powerful and efficient serve.

With repetition, the motion will become natural, and the power will come without extra effort.
