I often give advice to my students on body language when they are preparing for oral presentations. One important aspect of body language is gestures: what we do with our hands and arms as we speak? Do we put them in our pockets, behind our backs, in front of ourselves, or what?
The convention wisdom these days is that the steeple gesture is the most positive and confident starting position for the hands and arms when making a presentation. The steeple gesture, in case you didn’t know, generally involves the tips of the fingers on each hand being held together and the hands in front of the body, as shown in the picture below.
