Stretch Mobility Coaching

Can you avoid a hip replacement, or at least delay it? In this episode of The Healthy Movement Podcast, Kim Nartker walks through what the research actually shows about delaying hip replacement surgery and what standard hip testing will do for you and what it misses that you might be unaware of. You will learn why a "clear" X ray only means you do not have arthritis yet, and why it says...

Hip mobility after 50 is the question people keep asking me. Why do my hips feel like this when I did not do anything to cause it? In this episode I continue the hip series and break down what has actually happened to your hips by the time you reach 50. You will learn the four parts that make a hip healthy: the joint, the muscle, the nervous system and the cell inside that muscle. You will learn t...

Knee pain out of nowhere is the signal almost everyone misreads. You did not fall. You did not twist it. You got out of the car or stepped down a stair and your knee twinged, and now you are searching for stretches and exercises and trying creams and braces and inserts that work for a little while before the pain comes back. In this episode I break down what I find when I test somebody whose knee...

Sitting is not shortening your hip muscles. I read the research and it does not support what we have all been taught. I spent over 20 years as a PTA teaching people that sitting shortened their hip flexors and that aging was why they felt tight. This episode is where I show you what changed my mind. We look at what two studies on hamstring length and hip muscle length actually concluded. We look a...

Your hip flexor stretch stops holding after 40 and the reason has nothing to do with how much you stretch. In this episode I go through the actual stretching research and show you the number nobody hands you. How much stretching it really takes before your range of motion moves enough to count as a real change. Then I show you what happened when researchers stood those same people up and asked the...

Can you open up space in a tight joint without surgery or injections after 40. Yes. But not with stretching. There are two types of motion in every joint. One you can partly control and it is the one everybody measures. The other lives inside the joint capsule and you have no voluntary control over it at all. You cannot stretch it. You cannot strengthen it. You cannot foam roll it. And it is the o...

Your knee feels fine walking. Fine on stairs. Then you go down to the floor and there is a pressure. Most people call this pressure aging. and avoid that deep knee bend. It is not aging. Your knee has a lock and unlock mechanism you have no control over, and going to the floor is the only movement in your day that will tell you it has stopped working. In this episode I break down what that pressur...

Healthy Movement 101: What You Can Control, What's Stealing Your Movement, and the Gap Between Them This is the foundational episode — the one to start with, and the one to share when someone asks what healthy movement actually is. We cover a lot of ground. First, what you can control: why holding any position too long lets the tissues around your joints slowly deform and quiet the muscles that st...

You wake up stiff. Your back, your hips, your feet take a while to loosen up. You stretch, it helps for an hour, and the tightness comes right back. Most of us call this aging and move on. In this episode, movement coach Kim Nartker explains what is actually happening — a documented process the research calls arthrogenic muscle inhibition, and what she calls the Silent Shutdown Cycle. You'll learn...

In this "Ask Coach Kim" episode, Kim dives into the topic of muscle relaxers, looking at the research to see if muscle relaxers help improve tightness, stiffness and soreness like marketing of this drug says it does.

Your neck tightness is not a muscle problem. And that is the whole reason your neck tightness never goes away. You stretch it. It feels better for a moment. Then the tightness comes right back. You have been told this is tight muscles and bad posture. The research tells a different story. In this episode Coach Kim explains the real reason your neck stays tight. The tightness you feel is more compl...

You lift heavy. You eat your protein. You follow the program. And the orthopedic surgeon just told you that you need a joint replacement. How did this happen? In this episode, I break down the real benefits of strength training. What it cannot do for you. And the silent decline running underneath every workout that is loading uneven joints and building arthritis without you knowing it. You will he...

In this episode, Kim breaks down what is really happening inside your hip and why it feels stiff, tight, and stuck. If you are in midlife, menopause, or postmenopause, this one is for you. How a hip actually locks up and why it is not just aging Why your hip flexors stay tight no matter how much you stretch How sitting changes your joint capsule first and your muscles second Why dropping estrogen...

Your hips lock up and you blame age. You blame sitting. You blame your hormones. But it is more complex that this: In the show I break all of this down so that you better understand what happens in your hip in midlife and what you can do to protect your movement health. A locked up hip is not a muscle problem. It is a joint problem. And no amount of stretching will unlock a joint that has shut dow...

Your Movement Health Score may be the single most important number nobody has ever measured for you. In this episode, Kim Nartker pulls apart the word healthy and shows why most of us are only tracking one or two layers of it while the layer that decides how well we move gets ignored completely. It starts with her husband in the recliner. He asked her to work on his neck. She asked him to turn his...

Peter Attia and Dr. Abbie Smith Ryan had a powerful conversation on Women's Health and Performance. They covered training nutrition and hormones across life stages. But two questions hung in the air without answers. Why are older adults falling when they get bumped? And why is Dr. Abbie afraid of tearing her Achilles tendon when she trains? I am bringing the missing piece. The joint capsule and th...

Menopause shoulder pain is the warning signal most women miss until they are scheduled for surgery. In this episode, I walk through a real case from my studio. A 53-year-old woman in menopause came in with a Mobility Health Score of 85. Within 30 days, her score rose to 33, and her Movement Age moved from 85 to 81. She was getting better in measurable ways. Then she lifted a suitcase on a work tri...

In this episode, I’m talking directly to women in their 50s and 60s who have spent years giving everything to their families and are now wondering where they went in the process. If you’ve been feeling the physical, emotional, and mental weight of that, you’re not alone. I share real stories, break down the patterns keeping us stuck in guilt and overgiving, and explain what’s actually happening in...

There is a question a surprising number of people have stopped asking out loud. Why did physical therapy help for two weeks and then stop? Kim Nartker walks through what a 2014 randomized controlled trial in JAMA found when it compared standard PT to a sham treatment for hip osteoarthritis — and what 25 years of published research on Arthrogenic Muscle Inhibition tells us about the system undernea...

If you exercise consistently and still feel tight, stiff, and sore, this episode is going to change how you think about your body. The problem is not your workout. The source of your chronic tightness is inside your joints, and it has been running silently beneath every workout you have ever done. Kim Nartker breaks down exactly why exercise builds fitness but does not stop joint decline, and what...

In this episode, I’m breaking down why your rotator cuff is not actually the root cause of your shoulder pain. If you’ve been stretching, strengthening, or doing physical therapy and your symptoms keep coming back, there’s a reason. I explain what’s really happening inside your shoulder, starting with the joint capsule and how a silent loss of end-range motion triggers muscle shutdown, instability...

In this episode, I’m breaking down the language of healthcare so you can stop feeling like you’re the problem. After more than 20 years inside the system, I’ve seen how documentation is written for insurance and legal protection, not for you. That’s why phrases like “non-compliant,” “no clinical evidence,” or “patient appears to…” can feel personal, even when they’re not. I walk you through what t...
