Sam is about to begin his presentation. Which posture should he use while speaking?

Sam should adopt an open and confident posture while speaking, standing tall with his shoulders back and relaxed. He should keep his arms at his sides or use purposeful gestures to emphasize key points, avoiding crossed arms or excessive fidgeting. Maintaining eye contact with the audience will also help convey confidence and engage listeners effectively. Lastly, he should ensure his feet are shoulder-width apart for stability and balance.
