Body language refers to the non-verbal signals that you send with your posture, gestures, facial expressions, eye contact, and movement when you speak. It can complement, reinforce, or contradict your verbal message, as well as affect your credibility, confidence, and rapport with your audience. To master body language, you need to practice the following skills. Posture should be tall and straight with shoulders back and chest open to project confidence, authority, and professionalism. Gestures should be natural, purposeful, and varied to illustrate or clarify your message. Facial expressions should show emotions, reactions, and intentions. Eye contact should be made with the audience to establish connection, trust, and respect. Movement should be used to create energy, variety, and interest; for example closer to the audience for intimacy or further away for distance. Avoid slouching, fidgeting, masking or exaggerating facial expressions, staring or looking away from the audience and pacing or standing still as these can make you look weak, nervous, insincere or restless.
