Here's a must-read post from Laura Bergells with six "touchy-feely" tips that will help when you rehearse your next presentation (you do practice, right?). 

If you ever give presentations to clients, to peers or to juries, you need to be thinking about these practice ideas.  My favorite:

Record your presentation without video. Then, listen to it without watchingthe slides. I like putting my audio on my portable mp3 player -- andtaking a walk. While listening to myself on the ellipse machine at thegym last week, I found an area of my presentation that dragged sodismally, I barely registered a heartbeat while chugging along at ahigh incline! I went back to the office for a rewrite and added morepowerful visuals. Listening to "audio only" helps you spot pace andpitch problems -- but it also helps you later recall the words andinflections that work well.
