It's the combination of facial expressions, gestures, and movements that convey what's going on in your mind.

Practice strong, confident body language to fuel your presentation:

♦Stand up straight. If you're physically capable of standing up straight, then make sure you stand tall and straight during your presentation.

♦Assume the [power] position. If you're feeling stressed before your presentation, take a moment to stand in a powerful position. Doing this for just a few minutes will raise your testosterone and increase your self-confidence while reducing stress, anxiety, and cortisol.

One of the most popular power poses is the "superhero" pose: Put your hands on your hips, keep your chin up, and your chest out.

♦Be facially expressive. Your facial expressions should match the message you are delivering. If you're giving an upbeat speech, try to have a relaxed and joyful look on your face.

♦Plant your feet. Shifting your weight from side to side can lull your audience into a semi-hypnotic state (also known as sleep). Stand tall and firm.

If you feel that your stage presence is lacking, view clips of speakers you admire.

Aim to imitate parts of their style that you feel could work for you. Then, "fake it until you make it." In other words, act confident until you feel confident.
