How can you best hold your body when speaking in public?

Don't stand with your hands to your sides like a puppet or with your arms folded over like an angry mother-in-law, don't wiggle from leg to another like a metronome, don't put your arms behind your back like a police inspector on his round, don't put your hands in your pockets like a bum, or at least not your two hands at the same time. Study yourself in normal circumstances and how you move and gesture then. Copy that while you are presenting. Care make sure you do the same when you are presenting. Make your movements and gestures fit in the space. Large in halls and conference rooms, smaller in conference rooms and offices. Use your whole body. Stand up straight with your feet apart, your arms to your sides, ready to make hand gestures. That is the ideal basic attitude for any type of communication. Try to use all attributes. Pen, desk, paper, chair, table, pointer. Try to induce natural movement as much as possible. Movement is dynamism, dynamism is strength, strength supports you message and yourself.
