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.

In this episode, I’m talking about low back surgery and how you can prevent it. If you’re experiencing tightness or discomfort in your lower back and worry it might lead to surgery, this episode is for you.
I break down how most spinal issues—herniated discs, degenerative disc disease, and spinal stenosis—develop slowly over time and why pain is usually the last signal your body gives.
I explain how joint capsule restrictions, muscle shutdown, and poor spinal glide set the stage for injury, and why traditional approaches like stretching, massage, or rehab alone aren’t enough.
I show how testing your flexibility biomarker and resetting your system can restore joint health, improve muscle activation, prevent degeneration, and stop back problems before surgery becomes necessary.
