Fix your ball toss!
Many beginners and intermediate players struggle with the serve due to having a faulty ball toss.
Here's a quick tip to fix your ball toss from going over your head.
Problem: Erratic ball toss
Cause: Most players will usually lean back or bend their knees in the backswing.
Solution: Simplify the process.
Step 1: stand evenly balanced with the weight equally distributed on your feet. Don't rock your body at least in the beginning.
Step 2: Lean slightly forward as you release the ball. By leaning forward you will have your weight moving forward which will help keep your ball toss from going behind you.
