I'm going to show you how to play a lob.
The most important thing for the cross court lob is the height on the front wall.
Try and get it as high as you can. Then the width is important too, try and get it high and wide. So you know your opponent can't volley it.
It is one of the most under- rated shots in the game. It can be used to defend, and to convert defence into attack.
If you use a lob at the the right times, you'll be flying soon!
