A friend and I discussed this particular rider fault the other day, and it’s something I’ve touched on recently in a couple of lessons so it’s time for a blog post.
The ideal rider position has a vertical line from ear through the shoulder and hip, to the heel. The chair seat deviates from this because the vertical line is lost by the lower leg creeping forwards. When you look from the side, the rider’s outline is akin to if they were sat in a chair.
So why is the chair position frowned upon?
It’s most problematic in the rising trot. If you look at the ideal position, when you rise to the trot the lower leg stays under the body, and the rider can control their upper body so that they sit back into the centre of the saddle and immediately push themselves back out of the saddle. This means that the rider is quieter in their body language, more in control of their body and therefore more effective and precise with their aids. They are also more balanced, which means they are less likely to hinder the movement of the horse or be unbalanced by sudden movements.
Now think about the chair position, and imagine there’s a line going through the centre of the rider’s body, head to toe. If it were on a clock face the time would be 1.35, whereas the ideal position the line is vertical. Now as the rider rises from their chair position the lower leg swings back to balance the rider, who’s upper body comes forward. This means that the 1.35 line gets closer to the vertical when the rider is at the highest point of the rise. And swings back to the 1.35 position in the sit phase.
This means that the rider tends to sit down heavily onto the horse’s back, and towards the back of the saddle and the weaker part of the back. This heavy sit can damage the horse’s back, cause pain and unbalance them.
Collapsing into the saddle makes it harder for the rider to rise back up from the saddle. Which means they are hindering the horse’s movement further.
Ultimately in the chair position, the rider is less in control of their body so gives less effective aids, whilst also hindering the movement of the horse, and is more likely to be unbalanced by sudden movements.
So riding in a chair position makes it harder to influence the horse effectively because the crashing down movement of the sit discourages the horse from moving forwards, and the lower leg being further forward means it’s harder to apply the leg aid. Where the rider is sat on the back of the saddle they then find it harder to use their seat aid. Unfortunately this means that the horse is less inclined to move forwards and becomes “behind the leg” and lazy. This then causes the rider to try harder with the leg aids, which reinforces the chair position, and the lack of impulsion causes the rider to sit heavily back into the saddle, again reinforcing the chair position.
How do riders end up in the chair position? For young children, it’s often when they’ve been taught rising trot before they are strong enough, as the lack of strength in their legs and core means they need to swing their body up into the rise. The best way to overcome this is to make sure the saddle is the right size for the rider, and the stirrups the correct length so that the rider’s body is supported in the correct position. Then making sure the pony isn’t too lazy, so excessive leg aids aren’t needed. And then it’s just time needed to develop the correct muscles. One of my little riders falls back into the chair position every so often, and I find a useful analogy for her is that she imagines she’s sitting onto a pin cushion so she wants to sit as lightly as possible so she doesn’t get a sore bum!
For other riders, the chair position develops from a lack of core muscles and fitness, so improving their general fitness and not overdoing the trot work will help, whilst also working in sitting trot and without stirrups to improve their core muscles.
Along with a lack of fitness, riding a lazy horse when you don’t have the strength in your seat and legs means a rider’s position is compromised in order for them to make their aids more effective.
Sometimes a badly fitting saddle can cause the chair position: if the saddle is lower at the cantle then the rider almost has to rise uphill, which encourages the lower leg to swing. If a rider has a chair seat despite work on trying to improve it, and the horse being quite forwards it’s worth making sure the saddle fits both horse and the rider’s anatomy.
The chair position and a lazy horse makes a vicious circle, which is hard to get out of because the horse doesn’t want to move forwards with a “heavy” rider, and then the rider moves into the chair position as they try in earnest to persuade the horse to move.
To break the cycle, having the horse schooled by a stronger rider to remind them that they can travel forwards easily, and the rider improving their core muscles and position by riding a more forwards thinking horse. I recently lunged a client on her horse for two purposes. One, the horse doesn’t seem to understand the idea of lunging so we hope that having a rider on board will help teach him to stay out in the circle. Two, I can work on keeping the horse trotting forwards so his rider can really concentrate on her position and maintaining the vertical line throughout her rising. When she was more adept at keeping this position she took over from me, and found that her horse was more willing when she was sitting more lightly into the saddle and staying more balanced. Hopefully they can build on this in the next few weeks.
