Postures can make you feel powerful.

According to Kellogg School of Management, research shows that a 'powerful posture' can significantly impact achievements. When people position themselves in a way that opens up the body and takes up space — "posture expansiveness" — it activates a sense of power, producing behavioral changes independent of their ranks. Postures matter more than hierarchy in making a person feel, act, and be seen as powerful.
