Why Your Body Feels Stuck: Understanding the Role of Fascia

Most people believe tight muscles are the problem when their body feels stiff, restricted, or painful. But what if the real story lies deeper within the body’s connective tissue network? Understanding fascia—and its relationship with the nervous system—may completely change the way we think about movement, tension, and recovery.

So… what is fascia?

Fascia is the connective tissue that surrounds and interweaves every structure in the human body. It wraps around muscles, bones, organs, nerves, and blood vessels, forming a continuous three-dimensional web that holds the body together.

Until the 1980s, fascial tissue was routinely tossed in the bin during human dissections, regarded as little more than the wrapping that gets in the way of studying everything else. (So, I hear from my friends who are real academics).

It makes no sense to me that although every…single… body… is held together by fascia, and in a world now entirely designed around information being at our fingertips, so many of us still refuse to show any interest at all. I confess, I have spent 46 years in THIS body without even knowing the word fascia. But now, I am somewhat obsessed. Fascia is one of the body’s richest sensory organs and plays a significant role in how the nervous system regulates tension, movement, and coordination.

How fascia actually works

Fascia looks like one sheet of tissue when you tear it off your *biltong. (I am South African, so that’s the image that lands for me) But more universal: if you’ve ever carved a joint of meat, it’s the thin, silvery layer wrapped around the muscle; it looks like clingfilm. But fascia is a continuous, spiderweb-like connective tissue that wraps not only around muscles, but also around organs and other body structures. It consists of multiple-layered sheets made primarily of collagen fibres, with a gel-like liquid called hyaluronan between the layers that acts as a lubricant.

About 70% of fascia is water, which helps keep it hydrated and supple. It also hydrates through compressive movement, which pumps fluid through the fascial layers, keeping them supple and gliding smoothly. It’s designed to stretch as you move. But certain things cause fascia to thicken and become sticky.

From the gym to fascia

For more than a decade, my professional life has revolved around the human body.

My background is in strength and conditioning coaching, where I spent years helping people push their physical and often mental limits — lifting heavier, moving better, and discovering just how adaptable the human body (and even more exciting, the human mind) can be. Strength training teaches you something powerful: the body is remarkably resilient. It also teaches you — if you’re open enough to notice it — that it’s not as simple as “eat well, train hard.”

 I observed people who had never stepped into a gym before slowly begin to look forward to their sessions. I noticed the confidence that began to show in the way they carried themselves — a subtle dopamine shift just from showing up. New activewear worn with quiet pride. Running shoes moving to the top of birthday wish lists (not for a race, but because their lifestyles were changing). Again and again, it became clear to me that the real transformation was not about how they looked, but about how they were beginning to feel within themselves. This was the part of the work I fell deeply in love with.

 But the reality is that clients were paying me for physical results — six-pack abs and defined arms. And while some people responded well to traditional training, others didn’t. They wrestled with persistent tightness, fatigue, or recurring injuries, even when everything looked right on paper. I found this frustrating, and if I’m honest, it triggered a lot of self-doubt. I questioned my ability, my value, and whether I was missing something important. And looking back now, I can see how that state was quietly spilling into other areas of my life.

Until eventually — and almost by serendipity (as life tends to do) — I was led into the world of the nervous system, and from there into the connective tissue that weaves through the entire body, linking everything in ways I had never been taught to see.

 As I began exploring my own patterns, learning to recognise my body’s cues (both subtle and obvious), it became clear that I could no longer approach training in the same way. I couldn’t continue to ask people to push, adapt, and perform without first considering the state their nervous system was operating from. Because when that system is already under strain, adding more stress — even in the form of exercise — doesn’t always lead to progress.

When it starts to make sense

Because what I began to understand through my own journey — and through working with others — is that these internal states don’t just stay in the nervous system. They show up physically, and one of the primary places they show up is in fascia (that same connective tissue we so casually overlooked earlier). 

The way you move, the way you hold tension, even the way you experience pain — all of it is influenced by what’s happening beneath the surface. Over time, if the system is under constant load (physical, emotional, or both), fascia begins to adapt to that environment. It can become less fluid, less responsive, and more restricted — not randomly, but in patterns that reflect how you live and move.

 And this is where things start to get interesting… because what we often label as “tight muscles” is very often something much deeper.

It’s not just muscle

 Healthy fascia is smooth, hydrated, and able to move freely. But over time, certain patterns begin to change that.

 Too little movement (the kind most of us sit in all day), or the opposite — repetitive movement that overloads the same areas — can start to affect how fascia behaves. Add in injury, surgery, or prolonged stress, and the tissue begins to lose some of its natural elasticity. It becomes less fluid, more resistant, and in some places, almost sticky.

When this happens, fascia can create pressure around the muscles it surrounds, leading to those familiar hard, tender areas often described as “knots.” These points don’t always stay local either — they can show up as discomfort during movement, sensitivity to touch, or even pain that appears in a completely different part of the body.

This is often why something like shoulder pain doesn’t always start in the shoulder.

 And over time, this doesn’t just affect isolated areas — it begins to influence how you move, how you hold tension, and how your body feels day to day. Not always as sharp pain, but as a persistent tightness or restriction that never quite resolves. 

What’s important to understand here is that this isn’t just a tissue problem.

Because if the nervous system is still operating from a place of stress or protection, the body will continue to hold onto these patterns — regardless of how much stretching or release work you do.

Fascia meets the nervous system

When the nervous system begins to shift into a more regulated state, the body often changes in ways that are difficult to explain until they are experienced.

This is something I’ve observed repeatedly in clients working with TRE, and something I’ve come to recognise in my own body as well. Movement becomes more effortless. Breathing deepens without force. That familiar sense of holding, bracing, or tightness begins to soften.

For a long time, the fitness world has emphasised control, structure, and appearance — a body that is firm, defined, and held together. But in that pursuit, it’s easy to overlook what the body may be compensating for beneath the surface.

From a fascial perspective, this begins to make sense. Fascia responds to the internal environment in which it is placed. When the nervous system is in a heightened or protective state, the tissue can become less fluid and more resistant. Braced for survival.  But as that internal state begins to shift — as the body feels safer — the tissue can begin to reorganise, soften, and move with greater ease.

Strength, fascia, and the nervous system are not separate systems working in isolation. They are continuously influencing one another. And when one begins to change, the others often follow.   

This is where the conversation around movement starts to shift — away from pushing harder, and towards understanding what the body is responding to in the first place.

Because when the body feels supported rather than threatened, it no longer needs to hold in the same way.

And in that space, something very different becomes possible.

Start listening to your body

If you are curious about how nervous system regulation and fascia influence your movement, recovery, and overall wellbeing, exploring somatic practices may be a powerful place to start.

Your body already holds remarkable intelligence. Sometimes it simply needs the right conditions to express it.
