Exercise has an influence to the building of the main muscles and how they work together, that‘s why the rider has to have knowledge of them. The precondition for a correct over line is that the horse is without tension and stiffness.

Now I‘m going to talk in detail about chair position, cause and it‘s flaw. A chair position is called when the rider is pushing back from the deepest point of the seat to the back of the saddle. The pelvis falls back and the seating muscles are used incorrectly and are in bad shape to support the riders back.

An over line is an imaginary line that reaches from the back of the head to the heel. It‘s possible to imagine a line drawn from the throat at the front and under the belly to the groin and call that line underline. Horses can walk in a very different over line. Such as curved, stretched or straight.
