If I could change one thing in the teaching of riding, it would be that riders would understand the importance of supporting their own bodyweight, and coaches and instructors would acknowledge it as vital to the horseâs welfare, and ability to function well under saddle.
The ideal is to sit in such a way, that not only do you distribute your weight evenly and thoughtfully over the horses back, but also create a positive influence that allows space for the horse to lift and engage his back, to find his own âneutral spineâ.
In very simple terms, think of the horseâs body like a suspension bridge. The stanchions of the bridge are his shoulders and hindquarters, and his spine is like the road bridge in between.
If his back becomes hollow, then the bridge is soggy and the stanchions collapse inwards. Imagine adding a dead weight to the bridge that it was not designed to carry, (ie, the rider) and the bridge is further going to collapse. This analogy describes the situation that is far too often the norm for ridden horses, that not only are they coping with their backs being chronically hollow, but also trying to carry additional weight in that hollow.
Firstly, itâs important to understand how the horse has evolved to carry his own bodyweight, before we add that of our own and the saddle.
He has two systems, one for grazing and resting, and one for browsing, socialising and locomotion, which I will describe very briefly.
As a herbivore, consuming vast amounts of vegetation and water, his gut can become very heavy to carry around. In fact, the gut area of a horse can weigh around 300kg! However, horses have a very clever labour-saving way of coping with this.
Their intestines are slung inside a large bag of fascia (called mesentery) that is attached to the supraspinous ligament at around L2 of the lumbar spine. The supraspinous ligament runs along the back and then becomes the nuchal ligament as it runs over the withers and extends up the neck. When the horse lowers his head below the height of the withers, the withers act like a fulcrum, and as the ligament becomes taught, it starts to pick up the weight of the entire gut, purely by leverage and without any muscular effort. How cool is that?
However, when his head is above the height of his withers, this system does not operate so well, and instead he must engage his hindquarters, abdominal, lumbar, thoracic sling and neck muscles to carry his whole body, which we more commonly know as self-carriage.
So, having understood how the horse carries itself without our weight, what happens when we sit on their backs?
Well, if we add ourselves as a benign and relaxed passenger, we just become a burden to the middle of the suspension bridge, and it starts to collapse, which appears to the eye as a hollow. It also feels like you are sitting in a hollow, but for so many riders that I meet, they have become acclimatised to this hollow and have stopped noticing it, as if it is the norm.
Over time this will cause muscle wastage and chronic skeletal imbalance, plus a big loss of athletic performance. (Yes, it can be often seen in competition horses as well as happy hackers!)
I will often give a horse a belly lift while their rider is sat onboard, which allows the rider to gain a perspective on how the horsesâ long back muscles should feel if its abdominals are correctly engaged and pushing upwards. As the horses back sinks back down after the belly lift, it becomes clear how the hollow has become the norm.
A good question to ask yourself is, what does the surface of my horses back actually feel like? Does it feel toned and pliable, like it could lift and support me, is it flat and tense, or is it hollow and squishy like an old sofa? Is it level on both sides? Of course if you arenât sure how your own body feels, then you are not likely to be able to notice the horses body, which is why so much of my work is about developing riders to be able to feel and notice this physical interface, which has a great deal of nuance to it.
So what can we do to make ourselves less of the problem and more of the solution? Firstly, itâs important to be balanced over our seat bones in a shoulder-hip-heel alignment and stabilised against the forces acting on our bodies. Then the answer lies in our muscle tone, and probably a lot more physical effort then most riders want to acknowledge, in order that we can create some âsuctionâ over the horses back as opposed to âdeflationâ!
Think of the poise and control of an ice skater or ballroom dancer. They look relaxed, but also very light and balanced, in the same way that talented riders do. In the sequel to this post, I will explain the âhowâ of supporting your bodyweight and creating suction on the horses back.
