Short pendulum serves

i can now do topspin and side spin pendulum serve but i cant make a backspin really hard to return

how can i make it spinnier.

Hi Martin,

Try getting the bat under the ball.  Lay the bat back before you contact the ball.  Think about brushing the bottom of the ball to get the backspin.

To get more spin yo then need to brush the ball really fast.  I often describe it as attacking the serve.
