Most people when doing public speaking, giving a speech, or doing a presentation are nervous.  For many people it's takes more nerves to get up in front of people and do a speech than many other things in life.  Sometimes this anxiety makes one do some strange body movements.  Learn which of these that you need to avoid.

One of the most common are called "flipper" gestures.  Most of the time people plan to use gestures in the speech.  These are great when used properly.  For some though the anxiety takes over and the gestures become weak.  Instead of being full gestures, they are these small, pathetic ones that are done close to the body where most of the audience can't see them.  If you are using gestures, make sure that they are out in front of you and avoid doing these weak ones.

Some people have nervous ticks they might not be aware of.  Some people sway from side to side when giving a speech.  Some will move their knees back and forth.  Some mumble.  Others will move their head uncomfortable.  There are quite a few different ways this nervous energy can come out.  These are hard to identify but there are ways of dealing with them.

First of all, do your speech in front of a mirror and watch your body movements carefully.  Make sure that you aren't doing anything that might be because of the anxiety.  Once you can do the speech properly in front of a mirror, you need to do it in front of others.

Let them be critical of your body movements.  These will start to come out when in front of this smaller group.  When you find out what you are doing, concentrate on not doing those actions.  Practice with what you learn from them so that you don't have these habits when giving the real presentation.
