What are the key techniques for executing a proper underhand volleyball serve?

Answer 1

To execute a proper underhand volleyball serve, key techniques include standing with feet shoulder-width apart, holding the ball in the non-dominant hand, swinging the dominant hand back, stepping forward with the opposite foot, and making contact with the ball below waist level. Follow through by extending the arm and wrist, aiming to hit the ball with an open palm. Practice these techniques to improve accuracy and power in your underhand serve.
