A circle is simple, not “easy.”
A correct circle is a challenge to horse and rider. Every step the horse takes on the circle the outside of its body must be stretched from nostril to point of buttock. Every stride taken with its legs on the outside must be longer than the stride it takes with the matching leg on the inside of the curve. This is the only way a horse can be ridden “straight on a circle.” Without straightness, your horse will overuse parts of its body, no matter how well you ride.
