This small hop altho seemingly insignificant is a critical part of your footwork and success on the court
This small hop just before your opponent strikes the ball in effect tells your brain how to move once the ball has been struck - it tunes your brain into the muscles to instruct them as to when to move and in which direction and how fast.
This is a great illustration of how the brain talks to your muscles and eyes and tells them what to do and when!
So, next time you are on the court during practice (don't suddenly try new things in the middle of a match) give it a try - do the small jump just before your opponent strikes the ball and see how you do. Let me know as I bet it helps!
