Flexions

Flexions are a way to introduce the bit to the horse, and also a way to supple the horse. Flexions include asking the horse to mobilise its jaw, raising and lowering its neck, bending laterally right and left and flexing the poll.

Suppleness and mental cooperation

We all want a supple horse, but what does it mean? A horse is supple when there are no unnecessary muscle tensions. This means when you ask your horse to bend to the right, the muscles on the left side of the neck can relax and allow the bending to the right. The horse is supple.

In order for your horse to perform flexions well, he also needs to be relaxed and calm. A horse that needs to scratch his belly can easily bend his head all the way around to his belly. This does not mean the same horse will bend when you ask for it. If your horse does not bend when you ask, he either does not understand your request, and/or his muscles are tense. You might think your horse is stiff, but I would like to suggest it is more of a mental “stiffness”, i.e. lack of understanding or willingness to follow your hand, rather than a physical stiffness in the muscles. A well schooled horse will easily follow your signals and requests while being both supple and relaxed.

Flexion is not just a means for schooling physical suppleness, but also for mental schooling of the horse. As described by the Father of Modern Equitation, de la Guérinière, a schooled horse should follow the bit wherever the rider places it and flexions are a way to train this.

From the ground or in the saddle

You can ask for flexions either from the ground or in the saddle. Here I will describe how to introduce flexions to your horse from the ground.

First flexion: flexions of the jaw, “cession de mâchoire”

As I already mentioned, flexions are a way to introduce the bit to the horse. The horse should neither fear the bit, nor lean or brace on it. The horse should calmly move the bit with its tongue and through relaxation of the lower jaw be able to swallow. Therefore it is imperative that the nose band be adjusted so you can fit two fingers between the nose band and the bridge of the horse's nose.  

How to ask for the flexion of the jaw

Stand in front of your horse, assuming your horse can stand calmly. Place your thumbs in each ring of the bit. Lift the bit into the corners of the horse's mouth. Lifting the bit avoids pressure on the tongue and the bars of the mouth. In the best of worlds, your horse now responds by lightly mobilising the lower jaw. If not, you can try to either increase the pressure in the corner of the mouth or vibrate. Different horses respond differently so try what works best for your horse. As soon as your horse mobilises the lower jaw and the tongue let the bit drop down and hang in the cheek pieces, i.e. release of the hand. The goal is for the horse to calmly mobilise the jaw whenever the horse feels a light presence of your hand through the bit or the reins.  

Second flexion: raising and lowering of the head

The first part of the second flexion is the raising of your horse's head and neck. You begin as you did for the first flexion by standing in front of your horse and asking your horse to raise his head and neck by gentle upward rhythmic circular actions of your hands in the corners of your horse's mouth (demi-ârret). The height of the head you are seeking is the height your horse would take when looking out over an open field.

When you try this for the first time, your horse might try to back up instead of raising the head. If this happens you might have acted on the tongue or the bars of the mouth instead of into the corners of the horse's mouth, or you might have asked your horse to continue to raise his head even after he is as high as when looking out over an open field.

When the horse has raised his head to the proper height, and he is not leaning or bracing against your hand, he is standing still and calmly mobilizing the jaw, you stop doing the demi-arrêt. With correct training your horse will maintain this position, but the first time you ask this of your horse you want to completely remove your hands from the bit as soon as the horse raises his head, stands still, is light in hand and calmly mobilises the jaw.

The purpose of this flexion is to have a signal when riding which will ask the horse to remain light in hand (not lean on the bit), and to raise the neck which will shift its weight to the hind legs.

The second part of the second flexion is the lowering of the horse's neck, known as neck extension. It is important to teach your horse when he lowers his head he should also take his nose forward, so in neck extensions the nose is always in front of the vertical.

Third flexion: lateral bending

Lateral bending is asking your horse to take his head right and left. When bending the horse to the right, stand on the horse's left side. Place your left index finger in the left ring of the bit, the right rein is placed over the horse's neck close to the withers. Hold this rein between the thumb and the index finger of your right hand. When you ask for the flexion with precision, have a light contact on both reins or if you find it hard in the beginning to control both reins you can loosen the right rein.

Prepare your horse for the actual bending by having the horse stand with a raised head as if he was looking out over an open field (second flexion) and also mobilising the mouth (first flexion). Now ask for the bending by gently pushing your horse's head to the right with your left hand. If your horse is resistant to bending his neck, most of the time, the horse will also have his jaws locked. If this happens just ask for the first flexion until the horse again mobilises the jaw. If you press too hard with you left hand or ask for too much bend (more than 90 degrees) you might cause the horse to move his feet. The goal is to have the horse bend his neck 90 degrees while standing still and gently mobilising the jaw.

When your horse has bent his neck, is standing still with the ears at more or less the same height and he is calmly mobilising the jaw, you should reward your horse by releasing the bit and taking a step back. Let your horse decide when he wants to straighten his neck. If he stays bent for a moment after you release the bit it is a good sign of suppleness.

Forth flexion: flexion of the poll

It is important that you first have flexion of the jaw (the first flexion) and the second flexion (neck extensions) well established before you ask for the flexion of the poll otherwise you risk your horse taking his nose behind the vertical. The first (flexion of the jaw) and the third flexions (lateral bending) is the preparation for flexion of the poll.

Differentiate between local and systemic effect

When you ask your horse to either bend or do a full flexion, all you want is a local effect on the horse's neck. When you apply a direct or indirect rein you want a systemic effect on the whole horse that affects the horse's balance. With a well schooled horse you can ask for either a local or a systemic effect, or a combination of the both. In practical riding this means you can bend the horse either in the direction of motion or away from the direction of motion, or bend the horse and continue on a straight line, or ask for shoulder in or half pass, renvers or travers.

I hope this will help you understand the practical benefits of flexions for refined riding.
