Copying serving

Hi my name is Ambrosius...I wanna see the service technique from Zhang Jike,Ma Long,Kenta Matsudaira and Timo Boll...If u don't mind please show me in Video....Thank U Alois and Jeff :)

Hi Ambrosius,

This will be a big task for us.  Until then watch them doing their serves over and over.  This will give you good images in your mind of their serves that you will help you to replicate them.
