Racquet full drop
How do you achieve that huge racket drop that the pros do? Ihave seen Sampras serve on slow motion and the tip of his racket was so much low pointing to the ground.Is it a matter of flexibility? Amazing staff! I think this is the secret of having a great serve,coming up to contact from so far away from the ball.Pronation ,snaping of the wrist and the rest will come without thinking about it.
