Keep your Serving hand relaxed
Hold the ball like you would an egg and make sure you don’t hold it too tightly.
Relax your whole arm before you start your motion.
Use a stiff arm toss
That means that, your tossing forearm shouldn’t move for at least 3 seconds after you release the ball.
This is the most important point to keep in mind.
You want a steady toss and you want to place the ball in the same spot on every toss.
Because it helps you to focus only on your release point.
Start off slow
Your toss should start off slow and you need to flow into your motion.
Never do a quick toss during your motion, because this will only disrupt your timing on your serve.
Think slow, slow, and then whip through the ball with your service motion.
I don’t want to get too technical here on you guys in this article.
Club players need to focus on finding their release point with the toss and letting their serve flow, a great way to perfect the toss is to spend 10 minute before you start serving and place your racket about 2 feet to the right and in front of you.
Get in your service stance and relax your tossing hand.
The target is your racket face, hold the ball with 3 or 5 fingers, then pretend you are setting a dish up on your cabinet to get a better feel for the toss, see if you can do it over and over again.
Students should practice the serve toss for at least 15 minutes daily for a month to get their tossing action down, after that it should become natural to them.
