Posture: Proper posture during an oral presentation includes standing up straight and standing tall. As you stand upright, you also want to be relaxed and natural. Stand with your feet apart and your shoulders squared, facing the audience. A relaxed, straight posture will convey confidence and authority to your audience.
Avoid Poor Posture
Improper posture includes slouching or leaning. Example some presenters become overly nervous, and attempt to anchor themselves by shifting or leaning sideways. Do not lean on walls, tables or the podium. This appears overly casual. When an audience senses discomfort, it takes their attention away from the message at hand.
