Not just them rec lollipops . I haven't really been able to play matches in a while and it seems I've lost my old serve. Rather than try and recover it, I figured since it was the reason I injured my elbow in the first place, I should go and really work on improving it. Basically I have a couple of questions: *How are you supposed to swing the racket? Like do you swing using your elbow or your shoulder or something else? *How does pronation come into play? i.e. is it manually done or not? *What does fed/sampras do different that makes their serve way better than nadal/agassi? *Other key points that you think I should address Please try and dumb it down as much as possible to only the very basic essentials required to hit a good quality (aka 'pro') serve. Thanks in advance.
