The Power of Physical Intelligence: Unlocking Peak Performance with Kevin Chapman


Listen Later

What if the secret to scaling your business isn't just mindset or strategy — but mastering the intelligence hidden in your body?

In this episode of The Grown Up Business Podcast, Paul Avins is joined by Kevin Chapman — professional executive and performance coach, communication specialist, and co-founder of the Physical Intelligence Institute.

Kevin shares how our internal chemistry and neurochemistry largely dictate how we think, feel, and behave — and why most entrepreneurs are unknowingly sabotaging their performance by ignoring their body's intelligence. Together, Paul and Kevin unpack the science behind physical intelligence, how to strategically manage your internal state to access peak performance, and why understanding your body's chemistry is the ultimate competitive advantage for scale-up CEOs.

From managing performance anxiety and stress to unlocking creativity, resilience, and high-performing leadership, this conversation reveals practical, science-backed techniques that every entrepreneur can use immediately to perform at a higher level — in business and at home.

This episode is essential listening for founders and CEOs who want to stop sacrificing their health for wealth, master their state, and lead with clarity, energy, and sustainable performance.

  • How your internal chemistry (cortisol, dopamine, oxytocin, testosterone, serotonin, DHEA) dictates your performance

  • The fastest way to manage nerves and performance anxiety — through your body, not your mind

  • Why pace breathing (5 seconds in, 5 seconds out) increases cognitive function by 62%, reduces stress by 46%, and improves sleep by 33%

  • The difference between assertiveness and aggression — and how testosterone plays a role

  • How to reverse negative chemistry in your body using posture, movement, and breath

  • Why celebrating wins, showing vulnerability, and recognizing your team raises oxytocin and builds trust

  • The power of interoception — feeling your emotions in your body to build capacity, resilience, and empathy

  • Why walking for 20 minutes makes you 45% more likely to have a creative idea

  • How to shift from work state to home state in seconds — mastering state balance, not work-life balance

  • Why entrepreneurs sacrifice their health for wealth — and how to break that pattern
