Tightening Circle
Without Losing balance or Impulsion
Let us say that you are, ideally riding in a dressage arena. First ride a circle that has a diameter of thirty-three feet, the width of the arena. Make the center of the arena (letter X) the center of your circle. Make sure that the circle is properly arced and that the horse is moving on it properly bent throughout the length of his body. To aid you in establishing this proper circle, place a hub-cap at X to define the center of the circle. Put the letters E and B on the centers of the long sides of the arena. These are the only two points at which your legs pass the rail. Establish two other points on the circle where your line intercepts the center line of the dressage ring, and place two poles on the ground at these spots.
After you have established this circle and can move on it with a correctly bent horse in good impulsion, proceed to ride a spiral inward very gradually. Through spiraling inward, reach a smaller circle with the same correct bend and impulsion. Then spiral out again until you reach your original large circle of thirty-three feet diameter. The spiraling inward should only continue as near to the hub-cap in the center as you can manage to stay without losing either balance or impulsion. As soon as you notice either shortcoming, you should understand it as a sign that the circle is as small as the horse is capable of bending on without strain at this level of his development. Therefore, you should press no further. You should merely repeat the exercise after proper rest periods and refreshing, new movements.
In time the horse will be able to spiral tighter, to an even smaller circle. The ultimate goal, of course, is the circle call the volte, about 8 feet in diameter.
