What does LFS mean?

The first three keys of Straightness Training are also called the LFS:

1. L = Lateral bending

2. F = Forward-down

3. S = Stepping under

Keys of straightness trainingThe first key of Straightness Training is the lateral bending. With lateral bending, I mean the equal lateral bending of the body. By stretching short muscles and contracting long muscles, we teach the horse to bend laterally to both sides.

Keys of straightness trainingThe second key is the forward down tendency of the head and neck. In a standstill we can ask the head and neck into a forward-down position. In movement the forward-down tendency will be the result of the lateral stretching of key 1. By stretching the outside of the body, the back muscle on that side lengthens and a long back muscle cannot keep the head of the horse up, causing the horse to lower its head into a forward-down position.

Keys of straightness trainingThe third key is stepping under of the inside hind leg. Correct lateral bending engages the inside hip, causing the inside hind leg to step towards the center of mass. The forward-down movement of the horse makes the hind leg swing even more forward.

Now why are these three keys important?

A horse can not easily move with a stiff back and when he can’t bend to both sides its difficult to turn. When he doesn’t support his body weight with the hind legs, it mainly has to be done by the fragile front legs, which on the long term is not a healthy thing.

So when a horse is able to bend to both sides, to relax the back muscles and to support his body with the inside hind leg, he’s in a much better position to carry us as a rider.

Connection between the three keys

The three Straightness Training keys are closely connected:

  • The lateral bending relaxes the long back muscle, making the head of the horse stretch forward-down. On the other hand, a horse with a high head and neck cannot bend laterally because of the stiffness in his back. 
  • The lateral bending brings the inside hip of the horse forward, making the hind leg step under the center of mass. And the forward-down tendency of the horse activates the hind leg to swing further forward towards the point of mass so the hind leg makes a bigger step forward. Activating the stepping under of the inside hind leg will on the other hand improve the lateral bending.

So the first three keys are closely connected. One cannot exist without the others and the three keys must be trained in harmony.

That’s why I use the term ‘LFS’ to focus on these  three keys as a unit during Straightness Training.

Now there are three more additional keys:

Thankyou for keeping us informed on the details we all need to learn to become better for our horses throughout their lives.

Could you explain if there is a difference between " stelling " and lateral bending
