Everyone uses hand gestures while speaking in front of a group or crowd. It’s just a matter of using the right ones. Just make sure your palms are always facing up. Keep them open and unclenched, like you’ve nothing to hide. And don’t slash the air with your hands — just pretend you’re one-handedly dealing cards with your right (or left) hand. If you want to emphasize a point you’ve just made, “deal a card”. Another point, another card — simple. Every so often you can do a JFK finger-point gesture, but the main thing is to keep it simple and don’t over-gesture. Anyone who knows anything about public speaking will say the same thing. Make sure that your palms are facing the ceiling or the sky.
