Here's a sorry sight - i'm meant to be a grown up, and i went and practised my serve by hitting approximately 500 balls as hard as i could within the space of an hour yesterday evening - next time, i hope i take it easier. The coach says my grip's wrong - i never knew there was more than one grip - apparently there's a differnet grip you use when you serve, and apparently that's why all the pros don't look like this - that and the fact that they are healthy, and can actually play tennis.
