You Are A Devoted Horse Owner...

If you're like most equestrian riders, you want to understand your horse, connect deeper, and you would do anything for them.

But Something's Not Quite Right...

Your horse's movement and performance aren't as smooth as you'd like.

Perhaps you've even noticed your horse has a stronger bend to one side - something you've recently discovered from our quiz.

Despite your best efforts, you're facing challenges with your horse, such as: 

  • Stiffness
  • Resistance
  • Taking the bit on one side
  • Difficulty with turns and transitions
  • Uneven gaits or movements

These can really put a damper on your riding experience.

The Hardest Part?

You've been trying to help your horse, but feel unsure what to do about your horse's left- or right bend:

  • Is it severe? 
  • How bad is it? 
  • How will it affect us?

These questions might be spinning through your mind. 

You might be worried you're in over your head.

Perhaps you're even starting to doubt your own ability to spot the asymmetry.

And what if there's more to it...

Discover The Full Scope

Your horse being left- or right-bended is just one piece of the natural asymmetry puzzle.

In The Straightness Training Academy, we've identified 8 different dimensions of natural asymmetry.

Only once we assess the natural asymmetry in its full scope, we can start addressing it.

You, Too, Can Learn This Skill!


  • You, too, can learn how to recognize your horse's natural asymmetry!
  • You, too, can train your eye and identify the 8 dimensions of natural asymmetry!

Let me help you!

If you're new to me...

I'm Marijke de Jong, and I know what it feels like to worry about your horse - I've been there too.

I once had lots of concerns about my horse, Maestro, who was extremely right-bended. By discovering the full scope of natural asymmetry and using the principles of Straightness Training, I was able to address the root cause of his struggles and create long-lasting change.

I've since guided thousands of riders on a similar journey of transformation. It all begins with assessing the 8 dimensions of natural asymmetry in their horses.

That's why I'm excited to  invite you to the Natural Asymmetry Assessment Course!

Still Wondering If This Really Works?

Here's What Others Are Saying About The Natural Asymmetry Assessment Course:

Les E.

I'm totally convinced by Straightness Training to counteract Natural Asymmetry. Finally something makes sense about all the problems we've been experiencing with horses over the years. So excited to learn and walk the road on this exciting journey.

Jocelyn L.

Super cool that after being in ST for some time all these asymmetries just pop out and become so natural to observe and see. It's interesting to see that all horses that we have seen all have more or less the same asymmetries. 

Ilona Marianna H.

All very helpful, clear explanations!!! Thank you Marijke for all your sharing and thank you all who shared. All are very helpful and never enough to hear/watch till the knowledge/skill will be bulit completely in our cells.

Kerry L. B.

This was fantastic, and informative and so good to see so many people, on the same journey to better ourselves and our horses. Pro Equo, always!

Kit T.

Marijke you never fail to amaze me with your brilliance. I saw so much more this time. Climbing the ladder slowly but still climbing thanks to you

Åsa Möller

So interesting to see all the horses and to see that #nothinghasgonewrong with my horse ;) It is all just natural assymmetry!

Polina P.

Thanks a lot, Marijke! I have learned loads. As an owner of an Akhal-Teke I loved to hear this: "there is no carrying ability in the hind legs yet, but there is a lot of POSSIBILITY". Be a possibility partner!!!

Long storys short:

Because every horse is asymmetrical by nature. 

Overlooking this fact can lead to a whole range of physical and behavioral issues - regardless of the horse's breed or equestrian discipline.

Only a flexible, supple, strong and balanced horse will help you reach your goals. 

So it's crucial and essential to focus on symmetrical development in your horse's body and limbs.

This course has everything you need to assess all dimensions of your horse's natural asymmetry.

So if you're ready to become a pro at assessing and addressing natural asymmetry in your horse, then this course is for you!

A Fair Warning...

What if you ignore the 8 dimensions of natural asymmetry?

Well, you could keep running into these performance roadblocks.

Even worse, your horse's health could be at risk.

Without assessing and addressing the full scope of natural asymmetry, you might face persistent challenges in training and riding.

Don't let this happen.

Remember, the struggles you're experiencing are neither your fault nor your horse's.

They're simply the result of natural asymmetry - a common trait in all horses. 

With an assessment of your horse's natural asymmetry, you can be certain that you are taking the first and crucial step towards transformation.
