Jacob asks how often should he gesture during a presentation.

Although there is no magic number to your question, effective gestures are key. This allows you to keep your audience engaged and impacts your overall effectiveness.

Dr. Albert Mehrabian, professor and researcher at the University of California, Los Angeles, showed that 55% of the IMPACT you make on an audience is communicated through your non-verbal body language, which includes your gestures.

Make sure your movements are purposeful and your gestures give meaning to what you are saying.

Monitor the size of your gestures and put your arms to your sides when you are not gesturing to ensure that your arms aren't in constant motion.

Avoid mannerisms that distract your audience such as pacing, hands in your pockets or hands waving around.
