Have a look at the video above and it is explained what the difference is in the technique of Rafa Nadal's serve today in comparison to a few months ago.

With these adjustments he now produces a much faster more consistant serve.

But what is it that has made the difference - the arm in the video at 1.16 is too straight and so did not find the "trophy position".

But anyway take a look and also think of your own game that with practice it is possible even for us on our tennis planet to change something if we really want to.
