Andy Galpin is a PhD in exercise bioenergetics, professor at Parker University, and elite performance coach to professional and Olympic athletes.
This conversation explores his framework of nine fitness adaptations and why many people plateau in what could be called the "gray zone"—working hard enough to feel exhausted but not specifically enough to trigger adaptation. We discuss how movement quality often matters more than intensity, the difference between functional overreaching and overtraining, and what's actually limiting your progress.
Also, Andy coaches me through rebuilding movement patterns after spinal fusion surgery.
Andy translates complex exercise science into practical training wisdom. Enjoy!

Congratulations are not usually in order for someone who has been forced into hiding, someone whose children are scattered across continents for their safety, someone whose supporters are sitting in prison cells for the crime of believing in democracy.
But our guest today, María Corina Machado, just won the Nobel Peace Prize—joining the ranks of Nelson Mandela, Martin Luther King Jr., and the Dalai Lama, to name a few.
On Friday, the Norwegian Nobel Committee awarded their 2025 Peace Price to the Venezuelan opposition leader for her tireless work “promoting democratic rights,” describing her as “a woman who keeps the flame of democracy burning amid a growing darkness.” She is Venezuela’s first-ever Nobel Peace Prize winner.
Machado’s story, as Jonathan Jakubowicz wrote in The Free Press, “is a political thriller come to life. A 58-year old industrial engineer and former member of parliament, she spent two decades as the most relentless opponent of Hugo Chávez and his successor, Nicolás Maduro.” That thriller came to a head on July 28, 2024, when Edmundo González, Machado’s stand-in candidate, swept Venezuela’s elections with over 90 percent of the vote. But Maduro, Venezuela’s longtime dictator, claimed victory anyway and seized power. Since then, Machado has been living in hiding, her location undisclosed even to most of her allies, as the regime has arrested hundreds of political prisoners and issued a warrant for her arrest.
Machado has been nicknamed Venezuela’s “Iron Lady,” the same moniker given to Margaret Thatcher, who happens to be her personal hero. She represents what may be the most significant challenge to authoritarian socialism in Latin America, and we couldn’t be more thrilled to have her here today.

It’s been five years since Ben Greenfield joined me on The Dr. Hyman Show, and a lot has changed. Ben isn’t doing many of the things he once swore by. In fact, he’s discovered that some of the most powerful practices for health and longevity are simpler and more sustainable than the extreme routines he became known for.
In this episode, we talk about the biohacks he’s left behind, the innovations he still uses, and the deeper priorities that now guide his life. Join us on YouTube for the full talk or listen wherever you get your podcasts.

We discuss:
• How much exercise is truly healthy, and when it starts working against you
• Simple training shifts that build strength and stamina while protecting long-term health
• What recovery tools can actually speed healing and reduce inflammation
• Can light and oxygen really reset your body’s rhythms and improve sleep?
• Why community, family, and spiritual health may be the most overlooked keys to longevity
True longevity isn’t found in extremes—it’s built through balance, connection, and simple daily practices that stand the test of time.

Insulin resistance silently shapes the trajectory of nearly every major chronic disease, yet it's often overlooked until blood sugar abnormalities become obvious. In this episode, Dr. Ben Bikman exposes the dietary culprits that drive metabolic dysfunction and highlights actionable, evidence-based tactics for improving metabolic health. Ben also addresses pressing questions about popular weight loss medications like Ozempic and other GLP-1 agonists: Are they groundbreaking solutions, or shortcuts with hidden metabolic consequences?

Many people struggle with mysterious symptoms like fatigue, brain fog, food sensitivities, and skin issues—only to be misdiagnosed or dismissed altogether. This conversation highlights how histamine intolerance and mast cell activation syndrome can be the hidden drivers behind a wide range of chronic conditions, and why they're often overlooked in conventional medicine. From the role of gut health, food triggers, and environmental toxins to deeper root causes like Lyme disease or mold exposure, it’s clear that personalized, Functional Medicine is key to uncovering real answers. Understanding the immune system’s role in histamine reactions—and how even “healthy” foods can be inflammatory for some—is a critical step toward healing.

Dr. Cheri Mah returns to the podcast today to explore a few different topics including how circadian rhythms shape athletic performance. She notes that these 24-hour cycles regulate sleep, hormones, and core temperature, with peak physical capacity often occurring between 4-8 pm—when many world records are set.
Dr. Mah also discusses chronotypes, showing how tailoring training to one’s natural rhythm can enhance results. She reveals research on circadian disruption in sports, notably how West Coast NFL teams outperform East Coast teams in night games due to a three-hour body clock advantage. The episode also covers jet lag strategies, sleep loading, and managing fatigue, making it a must-listen not just for athletes and high performers, but truly for us all.
