Power Posing: How Your Body Shapes Your Mind
Adopting expansive body postures for just two minutes can increase testosterone, decrease cortisol, boost confidence, and improve performance in high-stakes situations like job interviews. Your physical posture doesn't just communicate to others—it fundamentally changes how you think and feel about yourself.
Why Body Language Matters
Nonverbals predict real-world outcomes
Body language judgments have measurable consequences: physicians' nonverbals predict malpractice suits, political candidates' facial expressions predict 70% of Senate and gubernatorial race outcomes, and emoticons in negotiations affect deal value. These aren't trivial social cues—they shape hiring, dating, and legal decisions.
We forget that our body language affects ourselves, not just others
While we obsess over how our nonverbals are perceived by others, we overlook that our own body language influences our thoughts, feelings, and physiology. The feedback loop runs both ways: our bodies shape our minds as much as our minds shape our bodies.
Power Dynamics in the Body
Universal expressions of power and powerlessness
Across the animal kingdom, power is expressed by expanding—making yourself big, stretching out, taking up space. Powerlessness is the opposite: closing up, wrapping yourself small, contracting. This pattern holds universally, even in humans born blind who exhibit the 'pride' pose (arms in V, chin lifted) when winning without ever seeing it modeled.
Power complementarity: we mirror the opposite
When someone displays high-power nonverbals, we typically don't mirror them—we do the opposite, making ourselves smaller. This complementary dynamic is automatic and shapes classroom participation and professional hierarchies.
Gender gap in power posing correlates with participation
MBA students show a full range of power nonverbals, with women much more likely to adopt low-power poses than men. This correlates directly with classroom participation, which counts for half the MBA grade, contributing to documented gender grade gaps despite equal incoming qualifications.
The Two-Minute Experiment
Study design: high-power vs. low-power poses
Researchers brought participants into a lab, had them adopt either high-power poses (like the 'Wonder Woman' stance—legs apart, arms raised) or low-power poses (folded, small, touching neck protectively) for two minutes. Participants provided saliva samples before and after, reported how powerful they felt, and were given a gambling opportunity to measure risk tolerance.
Hormonal changes from two minutes of posing
Two minutes of high-power posing increased testosterone by 20% and decreased cortisol by 25%. Low-power posing decreased testosterone by 10% and increased cortisol by 15%. These hormonal shifts configure the brain toward either assertiveness and confidence or stress-reactivity and shutdown.
Risk tolerance jumps with high-power posing
When participants adopted high-power poses, 86% chose to gamble. In low-power poses, only 60% gambled. This 26-percentage-point difference demonstrates that posture directly influences decision-making and risk appetite within minutes.
Real-World Application: The Job Interview
Job interview study design and conditions
Participants adopted high- or low-power poses, then underwent a five-minute stressful job interview while being recorded and judged. Judges were trained to give no nonverbal feedback (described as 'standing in social quicksand'), creating maximum social threat and cortisol spike to test whether power posing held up under real evaluative pressure.
Coders rated high-power posers as more hirable
Four blind coders watching the interview tapes, unaware of which participants had power-posed, consistently rated high-power posers as more desirable hires. The effect wasn't driven by speech content or qualifications—it was presence and authenticity. High-power posers brought their true selves without defensive residue.
Practical application: two minutes before high-stakes situations
Power posing works best before evaluative situations—job interviews, presentations, school board meetings, lunchroom social moments for teenagers. The ideal timing is in private (bathroom, elevator, desk behind closed doors) immediately before entering the stressful situation, not during it.
From Faking to Becoming
Personal story: impostor syndrome and identity loss
At 19, Cuddy suffered a severe car accident causing a two-standard-deviation IQ drop. Having built her identity on being smart and gifted, she was told she wouldn't finish college. She struggled for years, eventually graduating four years late, but carried deep impostor feelings into grad school and early academia, constantly feeling she didn't belong.
Advisor's intervention: fake it till you make it
When Cuddy considered quitting before her first Princeton talk, her advisor Susan Fiske told her to 'fake it'—to do every talk she was asked to do, even while terrified, until the moment arrived when she realized she was actually doing it and had become it. This wasn't about deception; it was about embodied practice until internalization.
The student who faked it till she became it
A silent MBA student told Cuddy 'I'm not supposed to be here.' Cuddy encouraged her to power pose and participate. The student not only faked it temporarily—she faked it until she genuinely became a confident participant. Months later, classmates hadn't even noticed her before her transformation.
Reframing: don't fake it till you make it, fake it till you become it
The distinction matters. 'Making it' implies reaching a destination while still feeling like a fraud. 'Becoming it' means the internal shift is real—you internalize the change through repeated embodied practice until your self-concept actually transforms. Two minutes of power posing is the seed; consistent practice is the growth.
Key Takeaways
Tiny tweaks lead to big changes
Two minutes of power posing before a stressful situation can reconfigure your brain's stress response, boost your hormone profile, and change how you show up. The intervention is minimal but the effects ripple through performance, presence, and outcomes.
Power posing is for people with no resources
The most valuable application is for those with fewest advantages—no money, no technology, no status, no power. They need only their body, privacy, and two minutes to significantly alter life outcomes. It's a democratized tool that requires nothing but intention.

Action items
- Before your next high-stakes evaluative situation (job interview, presentation, difficult meeting), spend two minutes in private adopting a high-power pose: stand with legs apart and arms raised in a V, or sit with legs spread and arms open on the armrests.
- Do this power pose in a private space—bathroom, elevator, or behind closed doors—immediately before entering the stressful situation, not during it.
- Focus on the internal shift: notice how your confidence, stress level, and sense of presence change. You're configuring your brain and hormones, not performing for others.
- Repeat this practice consistently in evaluative situations until the confidence becomes internalized and you stop feeling like an impostor.
- Share this science with people who have few resources or low status—they benefit most from a tool that requires only their body and two minutes.
