As adrenalin flows through your limbs, and your body gets ready for fight, or flight, and the lactic acid begins to build in your muscle tissue, so you will feel an overwhelming need to release that feeling of muscle tension by moving your legs – weaving. An advanced stage of weaving is prowling (like a caged carnivore) from one edge of the stage to the other. Don’t weave. Lock out your legs, shoulder width apart. Don’t bend your knees, or move anything below the waste. Make plenty of palms up hand gestures above the waist to show that you have no weapons and that you are engaging and empathising with the audience.
As a speaker, I loathe standing behind a podium when I speak – it feels like I’m preaching down from the pulpit and as far as I’m concerned public speaking is about conversation not lecturing. Also, a podium is physical barrier between you and the audience making it much harder to connect with them psychologically.
So wherever possible get out from behind that podium or lectern, get out on stage, move around, gesticulate and really CONNECT with your audience.
