Body Language

Body language is a vital form of communication which can make your presentation the best or worst. When your body language is deliberate it shows how confident you are, you are happy to be where you are and doing what you are doing. It makes you look more passionate about your job and current task that you are going to discuss. To bring movement to your speech and for a change, just walk in the space you have on the stage or where you are standing. Posture is one of the positive method of showing your sincerity , integrity and interest in your presentation and product, which makes you a good believer and helps you building a relationship with the audience. Our posture tells a lot about our level of confidence. You should avoid the following in your posture while you are presenting:

•  You should not fold your arms across your chest, that makes you slouch and makes you disconnected from the audience.
• Hands on hips, which makes you like a teacher or above the audience and sometimes it also shows that you are about to scold someone
• Rocking back or forth which makes you less confident and more nervous about what you are doing and how well you are prepared.

Gestures also help a lot to gain attention while you are presenting. You should always smile which makes you look a cheerful person and a positive attitude towards your job or given task. You should use positive gestures like nodding, that makes you look more confident.
