Why “Tight” Isn’t Always Tight

Most of us have believed the same thing for years, if something feels tight, we assume it is tight.

If our hamstrings feel tight? We stretch them, hips feel tight? Open them up, shoulders feel tight? Do more mobility work.

But that tight feeling isn’t always coming from a tissue that’s actually short, by tissue, I mean the physical structures in your body. Your muscles, tendons, ligaments and fascia. It’s not always that those structures physically can’t move, sometimes your body is limiting motion on purpose. Sometimes it’s what’s referred to as guarding, meaning it isn’t a mechanical restriction. It’s more of a neurological restriction.

Your brain is basically saying, “Hang on a minute, we’ve been here before. I’m not sure I like it, so it subtly reduces access to that range of movement

And here’s something interesting, if the restriction is mechanical (a physical block), it tends to be consistent. A joint that genuinely cannot move because something in the structure is restricted.

If it’s a neurological restriction, it often isn’t consistent. For instance, someone may struggle to raise their arms overhead while standing, yet regain that range when they’re lying down. Same joint. Different position. Different range.

In the golf swing, this kind of thing shows up all the time.

People often come into the gym saying their hips feel tight. But when we test this during the TPI screen, we find their hips actually do have range, and what they don’t have is control through the pelvis, or maybe the ability to disassociate their upper and lower body, which is something else entirely.

This is why stretching harder doesn’t always change anything, if the real issue is control or stability somewhere else, you could stretch that area for months and it may still feel tight.

The body isn’t just a collection of muscles. Different joints are designed to move in different ways, some joints are meant to be mobile. Others are meant to provide stability. When that balance gets blurred, the body still finds a way to produce a swing. But the movement may start coming from places that aren’t designed to deliver it optimally.
