Your body isn't being difficult. It's being protective.
One of the most common things I hear from riders - and from parents at the gate - is some version of this:
I know I'm gripping. I know it's not helping. But I can't seem to stop.
Or: She knows she needs to sit up. We've told her. The coach has told her. She just keeps doing it.
Here's why.
When most people hear "nervous system protective response" they picture a dramatic moment. A fall. A bolt. A near miss. Those absolutely register. But that's not the whole picture.
The nervous system responds to anything unfamiliar. Anything it doesn't yet have a map for. The wind past your ears at speed. Not knowing where your body is in space. A live animal shifting unexpectedly beneath you. A transition that came a beat earlier than expected. None of these are dangerous. But to a nervous system still building its map of this sport - unfamiliar and unsafe can feel like the same thing.
And so it responds. Automatically. Before a single conscious thought.
The gripping knee isn't just tension - it creates a chain reaction. Seat lifts out of the saddle, lower leg swings back, hips stiffen, and the rider can no longer move with the horse. The horse feels it immediately. Most riders know this. You can find it on YouTube in thirty seconds. And yet when the nervous system fires, the knee grips anyway. Same with the vice-like hands, the hollowed back, the flared ribs. The knowledge is there. But knowledge and nervous system response operate on completely different tracks - and in that moment, the nervous system wins.
The cruel irony is that every one of those responses makes riding harder, not safer. The body tries to protect itself and creates the very instability it was trying to prevent.
I sometimes demonstrate this deliberately. I'll ask an experienced rider to brace, grip, hollow, hold on - and the group watches what happens to the horse. It tightens, shortens, resists. Then I ask that same rider to do the complete opposite. The horse changes. Same horse. Same rider. Completely different conversation. No amount of explanation does what that moment does.
This is also why a good coach is managing several things at once. Teaching a new technique requires the rider to try something unfamiliar - which the nervous system will read as uncertain. So whilst the technical instruction is happening, an experienced coach is simultaneously watching for the protective response firing in the background. Push too hard and the system overloads. Don't push enough and the skill never develops. Getting that balance right is one of the most nuanced parts of coaching well.
Knowing why your body does this doesn't immediately stop it. But understanding it changes your relationship with it. And that is where things start to shift.
