Circles provide a foundation for all the other work and they are extremely useful throughout a training session. For a novice horse or rider, a circle teaches the basics of balance and engagement. For a more advanced horse, a circle rebalances and reengages them, that is, if they are ridden correctly.
A correct circle is very hard to ride for both horse and rider. Many horses fall in or out of the shape without the rider even being aware of it. The major benefits of the exercise are wasted, and poorly executed circles can leave your horse more out of balance before.
To quote Nuno Oliveira, “a circle is a correct geometric shape, not a potato or an egg.”
Whilst different trainers use different aids for a circle, the qualities that come from the movement should be:
- Suppling and strengthening the horse on both sides to create a more even and straighter horse.
- Engaging their inside hind leg to build collection and impulsion.
- Placing (or replacing) the horse round the rider’s inside leg and creating the connection to the outside rein.
- Creating a horse that is balanced, both left and right and from back to front, in preparation for another movement.
To ride a circle, the rider’s hips should match the position of the horse’s hips, and the rider’s shoulder should match the position of the horse’s shoulders. This means that they rider needs to rotate at their waist, advancing their outside shoulder without allowing their inside seat bone to follow the movement, which would bring their hips out of position.
Simply trying to make a circle by use of the inside rein only achieves a twisted and resistant position in the horse’s head and neck. The difference can be felt by the rider and can be clearly seen in the pictures below.
