Fascia is the key connective tissue below the skin that can cause a tight, knotted feeling. But show it some TLC and it will help you move well for life.


Fascia is like a full-body webbing: It keeps everything in place below the skin’s surface, wrapping your muscles, bones, organs, nerves and blood vessels in an interconnected network of collagen and elastic fibres. Every step and squat – and every hour sedentary – affect your fascia, says Arkady Lipnitsky, a chiropractor at Rebalance NYC wellness centre in the US. “If your joints feel stiff when you get up after sitting for a long period, you can blame the fascia, which has temporarily lost its elastic properties and fluid resilience,” says exercise physiologist Sue Hitzmann, a founding member of the Fascia Research Society. “Move around and the feeling goes away. That’s one big reason why movement is so essential.”
Over time (or because of an injury), fascia can tear, become inflamed or shortened, or stick together – you may experience those adhesions as knots. Consider the common case of plantar fasciitis, that underfoot pain you can get when running. The ache is caused when the fascia that runs from your heel bone to the front of your foot along the arch is inflamed from being repeatedly overstretched, says sports medicine physician Dr Jordan Metzl in The Athlete’s Book of Home Remedies. (The fix: rest from the off ending activity and gentle foot flexes.) Meanwhile, major adhesions can restrict movement and even prevent muscles from contracting efficiently, limiting flexibility, mobility and strength, Arkady says.

A great cardio workout that gets the heart pumping, running works not just the lower-body muscles, but also the core and auxiliary muscles. The biceps, for instance, are engaged when you pump your arms, while the core muscles work to stabilise the spine and maintain the correct posture to minimise injury during runs. Some experts have also said that cardio exercise can up the aerobic capacity of the fast-twitch muscles that give you strength and power to carry bigger loads.
While all exercises require willpower, there’s nothing like a long, steady run to test your mental strength. Once you fall into a comfortable rhythm though, you get to relax and reflect, which is why running is so therapeutic for many.
