The circle has to be round:
A horse that is not corrected for its natural crookedness and the natural balance, will fall on the inside shoulder or over the outside shoulder.
Natural crookedness is a muscular problem that can be corrected by proper training. The circle is a very useful exercise to straighten a horse. A straight horse:
- Can bend equally to the left and to the right
- Can do all exercises to the left and to the right
- Can push and carry equally in both hind legs
