About this listen

Founder of Stretch Mobility Coach™ and Creator of The Stretch Method®


Kim Nartker is a movement-health pioneer who has spent more than 20 years in the physical therapy field, only to discover the truth most of us were never taught: stiffness and tightness are not aging; they are early signs of joint decline.


After decades of working inside traditional healthcare, Kim realized there was a massive gap between what the system treated and what people actually needed. Science clearly showed a different story about movement health, nervous system protection, and joint mobility, yet no clinical model addressed it.


So she built one.


Through years of research, testing, and hands-on work with thousands of clients, Kim developed the Flexibility Health Test, the first assessment designed to identify joints that are in a protected, declining state—long before pain shows up. This decline in joint flexibility is the missing biomarker in movement health and the root cause of the stiffness, tightness, and early degeneration that millions silently struggle with.


Today, Kim teaches people that tightness isn’t “normal aging.” It’s a signal, just like the check-engine light in your car. And ignoring it sets you on a predictable path toward dysfunction, compensation, degeneration, and mobility loss.


Her mission is simple:


To help people restore their flexibility at the source, protect their joints for life, and expand their healthspan—not just their lifespan.


On this podcast, Kim brings her expertise, her honesty, and her passion for human movement to help you understand what’s really happening inside your body… and what you can do today to move younger, longer.


And for movement professionals who want to change lives the way she does, Kim also offers the Stretch Mobility Coach™ Certification, a complete training pathway rooted in The Stretch Method® that teaches providers how to identify, reset, and restore flexibility health in their own clients.

  • New Year’s Resolutions: Have You Gotten Your Flexibility Health Tested?
    Jan 13 2026

    In this New Year episode, I talk about something most people never think to test until pain forces their hand: flexibility and movement health. I share a real story from the clinic that shows how someone can feel “fine,” work out regularly, and still be quietly declining beneath the surface.


    I explain the difference between chronological age and movement age, why stiffness is an early warning sign, and how your nervous system compensates long before pain ever shows up. We dig into the silent decline cycle, the role of deep stabilizing muscles versus larger movement muscles, and why tightness is not just annoying, it is urgent.


    I also break down why pain is not the beginning of the problem, but the end of your body’s ability to hide it, and why waiting for pain often leads to symptom-based care instead of real solutions.


    If your New Year’s goal is to move better, stay strong, and protect your future, this episode will change how you think about flexibility forever.

  • A Healthspan Recap of What We Learned in 2025
    Jan 6 2026

    Happy New Year, and welcome back to the Stretch Mobility Coaching Podcast. In this episode, I’m taking the opportunity to reflect on what we uncovered over the past year about Movement Health and why it matters far more than most people realize.


    I recap the biggest insights from my research and in-studio work, including how movement health is different from longevity, wellness, and traditional healthcare, and why stiffness, tightness, and soreness are not just “normal aging.” I walk you through what movement health actually means, how joint capsules and the nervous system play a central role, and why pain is not a reliable indicator of whether your body is truly healthy or ready to move.


    I also share real client case studies from the studio, showing how stress, travel, holidays, and daily life quietly push the body into a state of movement decline, even in active, motivated people. You’ll hear exactly how flexibility resets work, what happens when deep stabilizing muscles shut down, and why stretching, massage, and workouts alone often miss the root problem.


    If you want to live longer and still move well, lift, run, travel, play with your kids or grandkids, and feel confident in your body at any age, this episode will help you see movement health through a completely new lens. I also share what’s coming next for the podcast, updates on my upcoming book, and how you can start taking control of your movement health now.


    Thanks for being here, and here’s to a year of moving better, not just longer.

  • Healthcare vs Healthspan: Why Joint Health is Not Covered By Health Insurance
    Dec 30 2025

    In this episode, I’m breaking down the difference between healthcare and healthspan and explaining why joint health is not covered by insurance.


    I talk about how your body actually works as a movement system, why tightness is an early warning sign of joint decline, and what’s really happening inside your joints, muscles, and nervous system long before pain shows up. I also answer the question I get all the time, “Does insurance cover this?” and why that question reveals a misunderstanding that’s costing people their independence.


    You’ll learn why stretching and strengthening alone don’t fix joint decline, how compensation quietly leads to stiffness, muscle loss, arthritis, and surgery, and what you can do now to protect your movement for life.


    I also explain what a flexibility health score is, why it matters, and how working with a Stretch Mobility Coach helps restore joint motion, reactivate deep stabilizing muscles, and reverse what most people accept as normal aging.


    Healthcare keeps you alive. Healthspan keeps you living. If you want to keep moving with confidence and independence for life, this episode is for you.
