Guest Episode: Why Flexibility > Optimization


Another sunny, semi-windy day here in South Padre, where your favorite nerd was back out playing in the wind again.

The best part?

Even after getting my lifting and rowing done, I still had plenty of energy left to go kiteboarding.

Wahoo.

A big piece of that is just doing the basics with violent consistency, as you know.

But the other part comes from the four pillars I teach in the Physiologic Flexibility Certification, which opens again this coming Monday:

  1. Temperature
  2. pH
  3. Expanded fuels (ketones and lactate)
  4. Breathing (CO₂ and O₂ regulation)

Today, in a guest podcast, we discuss these and tons more.

Metabolic Flexibility: A Systems Approach to Health and Human Performance << Spotify

In this episode, I sit down to talk about my work as an exercise physiologist and coach, where I focus on metabolic flexibility, performance physiology, and how we can use technology to improve human performance.

At the core of this conversation is physiological flexibility—the idea that your body isn’t meant to be optimized for just one state, but trained to adapt and transition efficiently across many different demands.

I break down how this applies to nutrition strategies, training protocols that build long-term adaptability, and how tools like AI are starting to shape the future of coaching. As technology continues to evolve, I also talk about which skills will still matter most in a more data-driven world.

If your goal is to build a more adaptable, resilient system, this is the framework I use.

Much love,
Dr Mike

Quick one before I head out to the water — wind is up and the kite is calling my name. Last Thursday I told you about the nootropic I accidentally took too many servings of at once. Ooops. Unlabeled sample bottle, assumed one serving, was emphatically not one serving, had one of the cleanest deep work sessions of my adult life and reported back to Tomer at Switch like a completely unrepentant human guinea pig. Since then, over 75% of the initial batch is already pre-ordered. Tomorrow the...

In this episode of the Flex Diet Podcast, I sit down with my good buddy Ari Whitten to talk all about red light therapy (photobiomodulation) and why it’s become so popular lately. We dig into how red and near-infrared light fits into an evolutionary sunlight context, why those wavelengths penetrate tissue differently, and how they can influence mitochondria, recovery, and performance. Ari also breaks down the confusing part most people miss: device choice and dosing aren’t one-size-fits-all,...

Back in SPI today — wind is up, so it's time for another "Send It Sundays." Little tired, but stoked after giving my talk at the Sports Pharmacy Summit down in Fort Lauderdale. Huge shoutout to Sean Casey and the whole crew for putting on an epic event — y'all crushed it. Had a blast nerding out on HRV and Met Flex, and it was great connecting with so many of you there. Here's what went down this week Newsletters: Cold Water Immersion and Your GainZ: Cold plunges might feel hardcore, but...
