Karch Kiraly of USA Volleyball talks about his specialty "flean" serve method: a clean and flat jump float serve.

Kiraly believes that the goal of the serve is to put the opposite team "out of system" - his team does so with the float serve, which is known for its unpredictable movement. The key points for the float serve: Solid hand contact on the ball, controlled toss in front of the body, and a controlled jump approach to the ball.

The float serve should barely scrape by the top of the net to maximize speed and should have little to no spin on them.
