A topspin serve in tennis is a serve where the player imparts forward spin on the ball, causing it to rotate forward as it travels over the net.

The main joints used in a tennis serve are the shoulder, elbow, and wrist. The shoulder generates the power and range of motion needed, the elbow helps in extending the arm for acceleration, and the wrist provides flexibility and control over the racquet. Coordination among these joints is crucial for a powerful and accurate serve.
