To master a successful volleyball underhand serve, key techniques include proper hand placement, a consistent tossing motion, and a controlled contact with the ball using a flat hand. Additionally, focusing on footwork and following through with the serving motion can help improve accuracy and power in the serve. Practice and repetition are essential to refine these techniques and develop a reliable underhand serve in volleyball.
