Pay attention to body language: stand up straight, take deep breaths, look people in the eye, and smile. Don’t lean on one leg or use gestures that feel unnatural.
Many people prefer to speak behind a podium when giving presentation. While podiums can be useful for holding notes, they put a harrier between you and the audience. They can also become a “crutch,” giving you a hiding place from the dozens or hundreds of eyes that are on you.
Instead of standing behind a podium, walk around and use gestures to engage the audience. This movement and energy will also come through in your voice, making it more active and passionate.
