This document discusses how adopting powerful body language can change your life. It summarizes research showing that brief non-verbal cues strongly influence how people are judged. The document then contrasts the body language of powerful versus powerless people. It describes an experiment where participants adopted either high-power or low-power poses for two minutes, after which samples found those in high-power poses had lower cortisol (stress hormone) and higher testosterone levels. The conclusion is that adopting powerful poses, even briefly, can meaningfully impact people in ways that lead to benefits like increased confidence and risk-taking.
