Myth No. 5 - Turning with Inside Leg and Outside Rein
For me this is quite a controversial topic.
At some point most dressage riders are taught that a correct turn or circle is established by (i) feeling with the inside rein to get an inside bend, (ii) pressure from the inside leg to stop the horse collapsing to the inside of the turn and finally (iii) contact with the outside rein to control the degree of bend and to prevent the shoulder from falling out.
I was certainly taught this when I was younger and I have done enough clinics to know that people are still being taught this almost as a gospel truth. In fact, many people who come to our clinics are shocked that anybody would question this golden rule.
So why do I know longer use inside leg and outside rein when asking a horse to turn?
Well, lets begin by looking at what is the function of the reins. I believe the reins have two functions. Firstly, they are meant to direct a horse's feet and secondly to shape the horse's posture (for self carriage and later collection). The primary purpose of the reins is to tell the horse where to go - forwards, backwards, left, right or stand still. This is what a breaker tries to instil in a young horse. But no matter how educated the horse becomes in life, he should never lose this basic understanding of the reins. With training the ability of the reins to direct the horse's feet should become more refined and softer and never be lost.
As some of you who have hung around me already know I strongly believe that a horse is always trying to do what he is thinking. If he is thinking to the right her will turn to the right. If we want him to go to the left and he is thinking to the right, there will be resistance to the reins which will cause him to be crooked and heavy in the hand. So if we want a horse to be soft to the reins, then the reins should be able to not only direct his feet, but also direct his thought. If we can direct his thought to the left by contact of the left rein, then he will turn to the left with no resistance - because it was his idea.
Most people miss this fundamental concept of the reins directing the horse's thought. The result they get is having to do much more to get him to turn to overcome the resistance of his thought wanting him to do something else.
Now read again what I have written regarding Myth No. 4. Go to any show and you will see horses circling that are crooked and mostly it is because their inside fore is not on the track of the circle. Instead it is stepping to the outside of the circle. Now look at where those same horses are looking. Most often you will see their noses turned to the inside of the circle, but their eyes are looking to the outside of the circle. Their eyes are telling you that their thought is to the outside of the circle. They are not looking to come around the circle, but rather to fall out of the circle. If the rider let go of the reins those horses would go straight ahead instead of staying the curve of the circle.
This is where the concept of the outside rein comes into play. If your horse is falling out of the circle with his shoulder, more contact with the outside rein will prevent it from happening because the outside rein acts like a barrier. The outside rein is like a wall stopping the shoulder from leaking to the outside. Try it yourself. Ride a circle with only inside rein and no outside rein. See if your horse is looking to the inside or the outside of the circle. Does his shoulder follow the circle or fall out of the circle? If it falls out pick up your outside rein with a firm contact. Did he suddenly stop falling out of the circle? If you did enough with the outside rein he should have made a change. Now let go of the outside rein again. Did he keep following the circle or did his shoulders fall out of the circle again? So there is no doubt that using the outside rein will stop your horse from falling out of the circle. But does it get a change in where the hose is thinking? Does he still have his thoughts leaking to the outside of the circle or did the inside rein change his thought and get him to think about following the curve of the circle?
If picking up the outside rein helped the horse be correct on the circle, but it fell apart when you let the outside rein relax again, then there was no change in the horse's thought. The outside rein did not change where he was thinking, it only put a band aid on the problem of the horse being crooked. If this is true then you will always and forever more have to use outside rein in the turns to cover up the flaw in the horse's training where the rein does not direct your horse's thought. The long term solution is to teach a horse to follow the feel of the reins with accuracy. This means being able to direct where he is thinking using the reins. If you do this, then contact with the outside rein to execute a circle or turn correctly is superfluous. If we don't teach a horse to follow the feel of the reins, then we are setting the horse up to be resistant to everything we do with them under saddle.
To summarize, the outside rein is used in turning a horse because it blocks the shoulder from leaking to the outside of the turn. However, the reason the shoulder is falling out is because the horse was not taught to follow the feel of the inside rein. Outside rein will not fix the cause of the problem, but it will cover it up - like putting paint over rust in a car.
There are times where outside rein is appropriate in training. In the main I believe outside rein has huge value when training lateral exercises like shoulder in, traver, renver etc. But when training a horse be correct in something as basic as a turn using outside rein is a poor substitute to teaching a horse to follow the feel of the reins with both his thought and his feet from the very beginning.
I am sure some people would debate my views on this topic and I welcome their input. Feel free to write to me because I think healthy discussion is a positive thing. Anything that encourages people to think about their training is a good thing whether or not they ever agree with me.
