Our muscles, bones and organs are held together by a network of tissue that influences our every move. Is there a way we can use it to our a
Fascia, the connective tissue that holds together the bodyâs internal structure, really hasnât spent all that long in the limelight. Anatomists have known about its existence since before the Hippocratic oath was a thing, but until the 1980s it 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. Over the past few decades, though, our understanding of it has evolved and (arguably) overshot â now, there are plenty of personal trainers who will insist that you should be loosening it up with a foam roller, or even harnessing its magical elastic powers to jump higher and do more press-ups. But whatâs it really doing â and is there a way you can actually take advantage of it?
âThe easiest way to describe fascia is to think about the structure of a tangerine,â says Natasha Kilian, a specialist in musculoskeletal physiotherapy at Pure Sports Medicine. âYouâve got the outer skin, and beneath that, the white pith that separates the segments and holds them together. Fascia works in a similar way: itâs a continuous, all-encompassing network that wraps around and connects everything in the body, from muscles and nerves to blood vessels and organs. Itâs essentially the bodyâs internal wetsuit, keeping everything supported and integrated.â If youâve ever carved a joint of meat, itâs the thin, silvery layer wrapped around the muscle, like clingfilm.
Physically, itâs made up of collagen, though 70% of it is actually water â and it hydrates through compressive movement, which pumps fluid through the fascial layers, keeping them supple and gliding smoothly. It also contains nerve endings that allow it to sense movement, pressure and temperature â and can influence posture, movement and proprioception.
âItâs constantly talking to the brain about what the body feels,â says Kilian. âItâs not a thin layer â itâs a massive, functional sensory organ system that holds us together.â

This, really, is the key. Fasciaâs nature means that it responds to what we repeatedly do, locking us into that set of movements and making anything else a little bit trickier. âOur bodies are smart,â says Kilian. âWhen we repeat the same activity, the body adapts to make it easier. For most of us, that means hours at a desk, hunched over a keyboard. Over time, we stiffen into that posture. So if you work long days and play cricket or tennis on weekends, you might feel it when you bowl or serve â your fascia has tightened from keeping your arms forward all week.â
The simplest way to start fixing this is to spend more time doing the sorts of movements you would otherwise do only occasionally. âI talk about it in terms of a circle of potential,â says Baker. âIf I tell a group of people to raise their arms as far as they can, then take a breath and raise them higher, theyâll always go up another couple of inches â the reason being that we have an extended range of potential that we very rarely go into. Thatâs our circle, and as we get older, we stop moving, that circle gets smaller. As the circle gets smaller, our connective tissue starts to get smaller, and that starts to limit us in what we can do. If Iâm 85 and I want to reach up and grab a cup off a shelf, itâs not necessary to have strong back muscles â I want a full range. Really, I donât think thereâs one range or one particular movement â the ultimate message is keep moving in as many different ways and ranges as possible.â
But fascia isnât immune to problems, and dealing with them can be a frustrating process. Many issues that can arise with fascia wonât be clear on, say, an MRI scan â which is one reason that deep-seated structural problems in the body can be difficult to diagnose.
So how do you start to fix it? Up until recently, many answers to this question revolved around the idea of rolling the sole of your foot on a golf ball, or lying down on your side to roll your iliotibial band (a tough strip of connective tissue that runs up the outside of your thigh, from knee to hip) on a big knobbly cylinder, in a process sometimes called self-myofascial release. But that may not actually be all that beneficial.
âThe current understanding is that you canât truly âbreak upâ fascia in the way many people think,â says Kilian. âWhile rolling your foot can help by increasing blood flow and releasing tension, itâs important to look at the body as an integrated system. You need to consider the tension in your glutes, hamstrings, calves and back â not just the area where you feel pain. Itâs the way all those muscles and fascial lines interact â or fail to â that leads to discomfort. In other words, donât mistake the victim for the perpetrator.â

What does this mean for most people? Maybe that itâs worth trying rock climbing â Baker runs his own group for over-50s â or swimming, dancing or pilates, all of which move the body through uncommon ranges and types of rotation.
But if thatâs all a bit strenuous, it might just mean taking the time to move more naturally. âThink about how a cat or dog stretches â or even how we naturally yawn and move when weâre relaxed on holiday, stretching our arms out,â says Kilian. âThe body instinctively knows which directions it needs to move in to release tension and free up restricted fascia. Even something as simple as a long, slow, diaphragmatic inhale during a stretch can help lengthen the fascia and encourage the whole system to move more freely.â
Thereâs still a lot more research to be done: as noted, weâve only just stopped throwing fascia away. But for now, just move as much, as often, and in as many different ways as you can.
