Know Your Physio
Knowing your physiology, the very science that makes you who you are, is the best thing you can do to optimize your health, bolster your performance, look and feel your best, and enjoy a longer and more fulfilling lifespan. My dedication to this field derives from a selfish place born out of necessity before it became the bright, selfless passion I'm known for. It was through my health journey (mainly battling ADD and ten years of Adderall dependency plus related side effects) and love for the scientific method that I found my way. Eventually, with the right knowledge and mentorship, I stumbled upon an enhanced state of awareness between mind, body, and spirit where healthy intentions met actionable steps and lasting, positive lifestyle change. Today I call this "physiological intuition," and to me, it's a right that every human being deserves to thrive with, without having to battle themselves or pursue a degree to discover it. Every day I spend on this planet, I get to connect with world-leading experts on my podcast and learn more of the substance I wish I could have gotten my hands on earlier, for YOU to apply and enjoy total mind and body fitness, personal mastery, and self-actualization! The more you #KnowYourPhysio… Enjoy the show!
