DON'T STAND BEHIND THE PODIUM
Try not to stand behind the podium. Standing behind the podium will create a barrier between you and the judge and/or jury, and block them from seeing your body language. Getting out from behind the podium will also make you more confident, as being able to gesture better as to your confidence. Additionally the witnesses, judges, and jurors will be more responsive to what you have to say.
WHEN YOU DON'T KNOW HOW TO GESTURE
If you feel awkward grab your thumb with the back of your hands facing the listener. Brian K. Johnson calls this the "Secret Hand Shake". This will help you feel less awkward in court.
Gesturing is an important part of the presentation. Much of gesturing is natural, and only natural gestures should be used. Brian K. Johnson gives the following threes types of gestures: 1) The give; 2) The show; and 3) the chop. See Brian K. Johnson on gesturing. While it's perfectly fine to practice these three types of gestures, I recommend only gesturing naturally in court.
DON'T BE SCARED OF SILENCE
Don't be scared of silence in court. People in general are often scared of silence while speaking, but judges and jurors understand lawyers having to look at notes or gain their thoughts. A small pause also gives the judge and jury time to digest what you said.
