Show Notes
In this episode, I talk with Anders Corbett, microbiome researcher and founder of Craft Microbiome, about how the bacteria living inside us may be influencing far more than we realize — from performance and recovery to cognition, mood, and long-term health.
Anders’ journey into microbiome science started at Harvard Medical School, where he sequenced his own microbiome as a former elite rower. What he discovered sparked a much bigger question: do elite athletes carry different microbial patterns than the rest of us?
That curiosity led him to study Olympic athletes, UFC fighters, NBA players, endurance competitors, and high-performing executives — identifying how certain bacterial strains correlate with inflammation control, lactate metabolism, testosterone signaling, VO₂ capacity, and stress resilience.
In this conversation, we explore the rapidly evolving science of the microbiome and human performance, including:
• How the microbiome shifts before and after elite competition • Inflammation-reducing bacteria found in endurance athletes • Growth-hormone–associated strains identified in sprinters • Gut changes after concussive and non-concussive hits • The gut-brain axis and its impact on mood and decision-making • How bacteria influence dopamine and serotonin production • Microbiome changes that tend to happen around 40 and again around 60 • Epigenetics and how microbes may turn genes on or off • Why sunlight, soil exposure, and environment matter for microbial health • How stress reshapes bacterial populations in the gut • The future of performance-focused probiotic formulations
We also talk about something many of us overlook: how modern life — sterile environments, limited food diversity, chronic stress, antibiotics, travel, and poor sleep — may be reducing microbial diversity and resilience.
Anders shares practical ways to begin supporting your microbiome even if you’re not a professional athlete — including simple shifts that may improve sleep, digestion, recovery, focus, and energy.
This conversation bridges cutting-edge science with something more timeless: the idea that our bodies are ecosystems. And it raises a deeper question worth considering:
Who’s really in charge — you or your gut?

Some days you haven't trained, haven't pushed, and still end the day wired and exhausted. What if the biggest drain on your energy is the voice in your head you keep mistaking for yourself? In this solo episode, I'm talking about the inner voice, the one that is you and isn't you. It's built to keep us safe, but in modern life it misfires constantly and drains energy meant for our people, our work, and our training. We cover the voices in your head, Byron Katie's four questions, and tools to separate a thought from a decision. This week, swap "I'm going to fail" for "I'm having the thought that I'm going to fail." Name it, check the facts, then choose your next move.
You can be strong, disciplined, and still spend every hour of the day braced for impact. What if the tightness you keep stretching isn't a mobility problem at all, but stress your body was never meant to carry?
I'm stoic by nature, yet this week my kids had me in tears twice and fantasizing about walking out the door. Being tired and stressed is the worst combination, and since your brain can't feel gratitude and fear at the same time, the real test is pulling the levers you already have when it counts.
You already know what would make you feel better, and you keep doing the opposite anyway. What if the fix isn't more willpower, but one small win and a new script running in your head?
After 50, your body starts to melt unless you give it a reason not to. It isn't rocket science, just the basics we tend to skip, done consistently.
