This isn't just another interview. I sat down with Dr. Stuart McGill to talk honestly about back pain, training, and all the stuff people get wrong online. We get into flexion, pain science, injuries, and how to actually train without messing yourself up long term. No fluff, no internet arguments, just a real conversation. If you train, deal with pain, or coach others, you'll get something from this. 00:00 – Introduction and Overview 03:11 – Addressing Criticisms and Flexion 10:46 – Epidemiology and Risk Assessment 14:04 – Core Endurance and Spine Hygiene 18:58 – Coaching and Performance Nuance 21:40 – Adaptation and Tissue Science 33:02 – Mechanisms of Disc Resolution 36:07 – Case Studies in Strength and MMA 44:49 – Refining the Assessment Process 50:25 – Neuroscience vs. Biomechanics 55:29 – Reintroducing Load and Progressive Training 01:00:37 – Future Directions and Closing https://chrisduffin.com/ Coaching, Peptides, Supplements, eBooks & Merch, Education, and my Free Community!

Today's conversation dives deep into hormone health and the myths surrounding testosterone therapy, featuring Shalin Shah, CEO of Marius Pharmaceuticals, and guided by host Chris Duffin with contributions from Anthony, our co-host.

We'll explore the stigmas and misconceptions attached to testosterone treatments, the groundbreaking launch of Kaisertrex (an FDA-approved oral testosterone capsule), and why hormone diagnostics matter for both men and women. Shalin Shah shares his journey as a passionate advocate for gender equity in hormone care and discusses how lifestyle, environmental factors, and stress impact hormone levels—especially as more young people experience low testosterone.

🏋️‍♂️ Beyond the Numbers—How You Feel Matters

The conversation moves beyond lab values to real-life outcomes: energy, mental clarity, resilience, and well-being. Plus, get some practical tips on what to test for, how to interpret the labs, and what questions to bring to your doctor.

Chris Duffin sits down with Nicholas Thompson, CEO of The Atlantic, elite masters distance runner, and author of "The Running Ground: A Father, a Son, and the Simplest of Sports." As they dive into Nick's multifaceted journey—from leading award-winning journalistic organizations to breaking running records after 40—you'll hear how the discipline and lessons from athletic pursuits translate directly into personal growth, leadership, and resilience.

Throughout their conversation, Chris Duffin and Nick Thompson (speaking on behalf of Nick) explore the intersections of family, career, and performance, drawing parallels between pushing physical limits and professional success. Nick shares candid stories about motivation, self-doubt, parenting, and the unique influence of his father—a journey marked by extraordinary accomplishments and deeply human challenges.

Here are 3 key takeaways worth sharing with you:

• Push Past Perceived Limits: Nick shared how his breakthroughs in running (and in leadership) often came when he challenged long-held beliefs about his own limits. Growth lies beyond what we think we're capable of.

• Resilience Requires Both Hard Work and Recovery: It's not enough to just "take care of yourself"—you have to get uncomfortable, stretch, sometimes fail, and then recover. That's where true resilience is built, whether in the boardroom or on the track.

• Lead by Example, Not by Force: As a parent, Nick emphasized living your values instead of preaching them. Kids (and teams) are most inspired when they watch you do the work, not when you tell them how it's done.

🔹 Lifestyle is the Foundation Peptides and supplements are powerful, but real, lasting change begins with the basics: sleep, nutrition, stress management, and movement. Without a strong foundation, high-level interventions just won't stick.

🔹 Peptides as Strategic Support, Not a Cure-All Used wisely, peptides can accelerate healing and provide "quick wins" when someone's struggling to get traction—but they should be paired with foundational changes, not used as shortcuts.

🔹 Test, Observe, Adapt Data from wearables like the Oura Ring and continuous glucose monitors can reveal trends, but it's the long-term patterns—not single-night stats—that matter. Effective protocols are built on critical thinking, ongoing feedback, and personalization.
