Are you sitting optimally? Does your tack allow your horse to move and do his thing? Things to consider every time we tack up and head out with our horse…..

What is organising your horse’s trot?
No, it isn’t entirely you.
(Sorry.)
Hidden within the spinal cord are networks of neurons called Central Pattern Generators (CPGs). These neural circuits organise the rhythm and repeating sequence of the horse’s gaits — walk, trot, canter and gallop.
Think of them a bit like the bass guitar in a band.
They set the rhythm that everything else works around.
The limbs are coordinated through these spinal networks so that the diagonal pairs of trot and the sequence of footfalls in walk, canter and gallop can happen automatically. In other words, the horse arrives with a built-in movement programme already installed.
This is why coordinated stepping patterns can still occur even when the brain isn’t consciously controlling every step. The spinal cord is perfectly capable of organising the rhythm.
Your job as the rider is not to manufacture the gait.
Your job is to avoid interfering with the system that is already trying to organise it.
The CPGs set the rhythm.
The tempo, however, is organised higher up in the nervous system — in the brain — and is influenced by things like balance, posture and how forces are travelling through the horse’s body.
When the horse is struggling with balance or compensating somewhere in the system, the brain may adjust tempo in response to those challenges, and the rhythm can start to feel less stable.
So when we work on improving rhythm in training, we are not really ‘fixing the trot’.
We are improving the conditions that allow the nervous system to organise the gait cleanly.
Which is quite reassuring really.
Because it turns out the horse already knows how to trot!
