The Truth About Fascia – It Doesn’t Just ‘Wrap’ Muscles & It Might Just be the Fountain of Youth!

So you’ve heard a bit about fascia by now..but do you really know what it is and how it functions in your body?

Fascia (otherwise known as connective tissue) has become quite the buzzword. Which is awesome!

When I started working with fascia in 2008 very few of my new clients knew what it was. Now fascia is a huge topic getting a lot of attention and all of my clients have at least heard of it. Many of the articles I read are spot on. And, a lot of them are – in my opinion – missing what I consider to be the most important details about this critical tissue.

If you’ve been wondering what all the fuss is about, this post is for you!

What is fascia?

In its simplest definition, fascia is a collagen-like substance that separates and connects almost everything in the human body.

Most people are familiar with the kind of fascia found in a steak or chicken breast, because this is similar to the fascia that wraps our muscles – and this is still what most people think of when they hear the word fascia.

But what most people do NOT know is just how much fascia we have, how critical it is for our entire well being and that it’s found in the tiniest of places down to the cellular level.

We have more fascia than anything else, certainly more than muscles and bones!

Fascia wraps every single nerve ending and nerve, every fibril of muscle tissue as well as the fiber (which is made up of multiple fibrils); it wraps every muscle bundle and muscle group and then turns into tendon and ligament (also fascia), which connects to our bones, also wrapped in fascia. It wraps our organs too.

When we observe fascia at the microscopic level and THEN zoom out, things get really interesting. This is about to get sciency, so hang with me.

Why is fascia so critical?


I think we can all agree that nerves – and the nervous system – are critical for us to function optimally every moment we’re alive, right?


Every nerve in the body is a cordlike structure containing bundles of axons. Within a nerve each axon is surrounded by a layer of connective tissue (fascia) called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. Then, the entire nerve is wrapped in a layer of connective tissue called the epineurium.

Fascia wraps each part of a nerve and every nerve in its entirety, and we have a hundred billion of them!

The implications of this fact alone are enormous, and largely unstudied or talked about.

The nervous system is the master regulator of everything that happens to and within us in our lifetimes. Every thought we think produces a feeling, and every single feeling is FELT in the body as sensation, via the nervous system.

I’m convinced the fascia feels everything that our nerves do – perhaps on an even more intense or widespread level.

Take fear for example: whenever we feel fear we tend to experience it as anxiety or adrenaline, tension or stress. When we feel joy it’s often described as light, expansive, buoyant. Our feelings and actions every day direct the hormone cocktail released by the brain to regulate whatever state(s) we’re in.

Literally everything that happens to us in life – good and bad – is felt and recorded within the fascial structure or system.

I also have it on good authority (from an orthopedic surgeon) that fascia bleeds a LOT more than muscle when cut into. Fascia contains more of our blood supply than anything else. This fact alone also gives fascia an incredibly important role – by being the main source of fresh blood within the body.

Healthy fascia gives us “spring” (aka, it’s our shock absorption!)

All connective tissue has within it something called ground substance, one of the most important elements in the human body.

Ground substance is an amorphous gel like substance that surrounds every cell; it contains the nutrients that FEED every cell in our body, AND it takes the waste excreted by every cell and ushers it out of our body.

So basically – fascia is our nutrient AND waste distributor!

That’s not all though…

This ground substance is part of the extracellular matrix (or ECM) which is responsible for distributing mechanical stresses and tension throughout the entire system when force or compression meets the body.

It is THIS part of the fascial system that is most responsible for being our shock absorber!

Activities like walking and running, jumping and dancing should all feel easy and create minimal impact on our body – if the fascial system and its ECM are healthy.

However, most people today have relatively (or extremely) unhealthy fascia.

That means even if you’re not in pain, you may have fascia that’s become dehydrated, brittle, and stuck to itself in knots. These adhesions pull the muscle tissue with them, as well as our attachments (tendons and ligaments), and it is for this reason that we get joint pain like knee or hip pain or elbow tendonitis.

If you get shin splints or heel pain through activities like running, or a stress fracture in your foot, then you can be almost certain your ECM has lost its spring.

Also, if we have brittle or dehydrated fascia, then our cells aren’t getting the nutrients they need! And when our cells excrete waste – if the fascia doesn’t have fluid and space to usher out toxins, they get stored instead. The #1 place the body likes to “hide” toxins (where they can’t poison us) is in our FAT!

If you have serious difficulty losing weight and your fascia is brittle, maybe this has something to do with it. (Obviously diet and activity levels have more to do with it, but it could potentially contribute to difficulty in my opinion), because our bodies won’t let us lose the fat unless it can also usher out the toxins stored there.

For our cells to be healthy and free of waste, for our muscles to glide freely, for our tendons and ligaments to feel securely attached, for our joints to get nourished with blood and ground substance – our fascial system needs to be spacious AND lubricated with ground substance.

Think of a wet sponge vs a dry hard brittle one – the wet sponge represents healthy fascia that’s springy and full of ground substance that feeds our cells and ushers out toxins. The dry dirty sponge represents brittle fascia that has lost ground substance, so waste gets stuck there and the fascia has lost its ability to distribute compression and outside force.

This should give you a small window into the importance of connective tissue and just how abundant it is in the human body!

So yes it wraps our muscle fibers in a more linear way which is how most people talk about it, but because of the way it also coats or surrounds our axons and nerves, it’s really more like a vast criss-crossing matrix.

Since it wraps literally everything in the body that supports LIFE, I have come to believe it is meant to be mostly unchangeable, resistant to any force trying to manipulate it – after all, this is the main FUNCTION of the ECM! The instinct of the ECM when ANY force or tension is applied to the body is to distribute that force and tension to as much of the system as possible in order to protect our blood and cells, every nerve, every muscle, organ and bone in the body from outside harm.
This is one reason why you might get sore from deep tissue massages, and why most manual manipulation techniques don’t actually work to change the fascia.
Fascia needs to be recruited to change itself. If you want to read more about this particular “fascia secret,” click here. I did an entire blog/episode on this!

The good news is: unhealthy fascia can become healthy again!

This is what I’ve devoted my life to, in my private practice as well as here on Mobility Mastery.

Healthy fascia means little to no pain; it means you’ll literally have ‘spring’ in your step and be able to jump, run and hike down mountains without knee pain; it means your cells are getting what they need to thrive and your nervous system and fascial system are in sync and optimized for an active unstoppable life.

Everything I do here at Mobility Mastery is done out of a desire to empower you to trust your body and stop fearing pain so you can adventure through life with confidence.

Unfortunately, most people learn just enough about fascia to get themselves out of pain and stop there.

An undaunted, curious, committed and persistent few of you will actually use this information to not only get out of pain, but feel better than you ever imagined possible.

I hope that’s YOU!

    I would like to know if you have come across any information that supports the claim that fascia does not yeild to outside forces. Ie. A text book or science journal. I believe this as a practitioner myself. Just want to find a source credible enough to support the claim. Thank you.

    • Hey Stan – that’s a great question. I don’t know of any peer reviewed studies or anything like that which would substantiate my claim. In fact, I know of some studies that say fascia can’t be changed and “foam rolling doesn’t work.” I’m pretty sure for every peer reviewed study making one claim, there’s another that proves its opposite true 😛

      All I can go off is my own personal experience working ten thousand hours or more with clients since 2008. Everything I’ve learned about fascia I learned from stepping on people for a living, and I got a front row seat to FEELING the changes occur as time went by. When I first started, I didn’t know fascia could get to a place of optimal health, to the point where I could stand on someone’s IT Band with my full body weight and it not hurt at all. I’ve experienced these physiological “rules” myself, and seen them with clients over and over. Some people claim that the nervous system is the only thing that grants “change” in tissue. I buy this theory, but only to an extent. I believe the nervous system will allow neural pathways to change, and allow the brain to stop perceiving one pattern and perceive another (say – stop perceiving back pain and instead perceive everything is fine). However, I don’t think this automatically equates to supple adhesion-free fascia. But using compression and movement based fascial release WILL create this change in most people when done consistently. And, it goes back to a restricted state if the maintenance stops for a longe enough period.

      What kind of practitioner are you?

      Thanks for chiming in with your question, I always love “needing” out with people 🙂


  • Eric says:

    When communicating science to the masses it is important to cite your sources. Great information except for the lack of references.

    • Hey Eric – the science info I relay regarding anatomy and fascia is freely available via google, there are varied sources available for these facts and I draw from many. I actually don’t want people to just take my word for it, so if having no sources for the science prompts someone to take to google…I would consider that a win. I encourage everyone to do their own research! The rest of what I communicate here is just that: it’s based on my own research, findings, experience and opinion after working with people in pain via fascial release since 2008. My most trusted and valuable source of information is the human body, and the many clients I’ve worked with, as well as my own experience with injuries and healing. Thanks for stopping by!
