Does this sound like your horse?...

  • Having a "good" and "bad" side
  • Being heavy on one rein
  • Not willling to go "on the bit"
  • Lacking forward in walk
  • Irregular in trot
  • Difficult to canter to one side
  • Pushy in one direction
  • Easily upset or spooky
  • Being good, but not great
  • Having a good and bad side
  • Being heavy on one rein
  • Not willing to go "on the bit"
  • Lacking forward in walk
  • Being irregular in trot
  • Hard to canter to one side
  • Pushy in one direction
  • Easily upset or spooky
  • Being good, but not great

First, let me tell you—you're not alone!


Thousands of riders have been sharing these exact issues with me in lessons, workshops, clinics, emails, and on social media (and I'd bet that these problems are familiar to many more people!)

They feel frustrated or disappointed because they know that not fixing the issue means staying stuck—either at the same level or in their struggles—FOREVER!

 

Here's the truth—it's not your fault! 


The real reason that your horse is difficult to ride or hard to train? 

It's a hidden force almost nobody talks about.

Chances are, no one has ever taught you how to recognize and handle it—until now.

 

Meet the Hidden Force holding you back...

Your horse's natural asymmetry is an invisible power that stands in the way of the results you're looking for.

And even worse...

Unaddressed natural asymmetry can RUIN your training session, your equestrian journey—even your horse's life!

What if you could finally and easily overcome your struggles?

  • What if you were able to end unnecessary suffering caused by your horse's natural asymmetry—once and for all?

  • What if, instead of feeling frustrated and stuck, you could experience a whole new level of harmony and balance with your horse?
  • Picture yourself achieving things you once thought impossible, where you and your horse move as one.

It’s No Secret...


If you learn how to train your horse (and in the way I'll be showing you on this page),
then you'll have everything you need to create balance, harmony and real change. 

 You, too, can have the horse you’ve always dreamed of!

From: Marijke de Jong

Location: Lisbon, Portugal

Dear ST enthusiast,

No matter your experience,  equestrian discipline, or your horse's breed or age... learning how to balance your horse – using my horse-friendly and proven "Straightness Training" formula – can help you create real change for you and your horse, getting the balance and harmony you've always dreamed of. 

After having some very crooked horses myself, and after decates of teaching other riders of all levels, I can honestly say that unlocking the magnificant giant within your horse is one of the most fulfilling and rewarding adventures you can experience in this lifetime.

I also believe that the horse world will improve immensely when more horses are developed  not only physically, but also mentally, emotionally and spiritually  by people like YOU! People who put the well-being of their horse first! 

Now is this program for you?


Let me quickly describe the nature, mindset and experience of the person this program is designed for...

  • IF YOU WANT MORE! 
    You're just starting out, or for whatever reason, you're struggling with your horse, not getting the results you want, or you feel like you're stuck— then this is for you.
  • IF YOU WANT TO GO FROM GOOD TO GREAT! Right now, you're pretty good in training your horse... but you dont want to settle for "good"; you want to be great—then let's take your game to the NEXT level.
  • IF YOU'RE AN INSTRUCTOR!
    If you're an instructor and struggling to overcome the natural asymmetry of your students' horses—then this is absolutely designed and made with you in mind!

If any of these sound like you, keep reading...


This could be the most important and game-changing program for you and your horse!

 

I'm Marijke de Jong and over the last 20+ years, I've been sharing all of my Straightness Training secrets in front of thousands of riders from all backgrounds at my in-person and online events.

With my experience, I've been fortunate enough to help riders go from not knowing how to balance their horse... to eventually doing the piaffe, pirouette and other amazing things!

Each of these journeys has proven that with the right guidance, every horse and rider can achieve real harmony, balance, and connection.

And if they could do it, so can you!

 

That's why I've put together the ULTIMATE A to Z of learning how to overcome your horse's natural asymmetry with Straightness Training (ST), and become the amazing horse trainer you're meant to be!

Get Coached & Get Feedback on Your Videos

When you're actually training your horse, questions might start popping up: "Am I doing the right things?" "Am I doing it right?" 

That’s exactly why, each month, you have the opportunity to submit a video of you and your horse practicing Straightness Training—we call this a Touchstone.

Here’s how it works:

  1. Watch the exercises in your library and read the tutorials.
  2. Put the theory into practice with your own horse.
  3. Record a quick video—no need for perfection, just capture your progress. 
  4. Send me the video, and within days,  you''ll get my personalized feedback.

This approach helps you progress easier, faster, and better.

And the best part?

It's included in your membership—Value €167/m

By the end of 8 weeks, you'll have:

  • The clarity on how to rebalance your horse's body and mind from the ground.
  • The feedback that you do the right things and do things right.
  • The confidence that you, too, can train your horse effectively.
  • The certificate for mastering the groundwork exercises at the level of grade 1.

Here's how it helped Ivana & her two horses transform:

Ivana Kovaříková & Spotty Doc Chex

"The video evaluation I see as the most valuable part. Monthly Touchstones are my routine now. It helps me enormously to keep the right track in the ST journey."

Ivana Kovaříková & Tesstino (OTTB)

"After completing my Touchstones on the level of grade 1 and grade 2, I can see and feel so many changes in myself and my horse. If I hadn´t chosen this path, we would probably be struggling with his physical issues and misunderstanding."

One Thing Can Change Your Whole Life


Now, as attractive as this program is, not all ST enthusiaSTs will become a STudent. Although that’s okay with me from a 'business' standpoint, it still bothers me personally.

You see, I know how much our Scholars and their horses benefit from our program. I read their emails, I talk to them during live sessions, I see them personally on one of my clinics, and hundreds each year tell me that becoming a Scholar in the ST Academy not only changed their way of training horses, but that "it changed my whole life”—just listen to these STudents:

Real STories, Real Success

Here's proof that the ST Mastery Scholars Program works:

★★★★★

"This is an AMAZING program. I have studied many different dressage and natural horsemanship programs - nothing helps the horses and riders to the degree that this program does. This program brings everything together. I am a lifelong student of dressage, I have read many books and been looking for the secrets of the Masters. When I had the good fortune of coming across this program, I did not hesitate to sign up. I could see that this was what I had been looking for all these years. Dressage seems to have become such a struggle for many, and this program put everything into place for me. I no longer feel the need to look for the secrets and answers to the same degree as before, I understand what and where most of the struggle and problems are arising from. Natural Asymmetry. I now have the basic tools to fix this!"

Kirsty, USA

★★★★★

Maria Retyunskaya & Ave Maria (German Warmblood)

"During these years with ST, me and my horses have changed mentally and physically. I’m happy for me and for Ave Maria. We made it together and it is not the end but the beginning of a new journey of discovery."

★★★★★

"My young gelding had no balance and couldn't bend. In an arena if we trotted or cantered we would get faster and faster - like a motorbike - and fall in on the corners. It was awful. He would brace against attempts to slow or bend him under saddle. His anxiety saddened me, and so I resigned myself to only riding him out on quiet trail rides. By accident I found ST. Now, when I change from one seat bone to the other, I feel his whole body change bend! The in-hand exercises have brought us closer together and opened up a whole new way of interacting. Sometimes we just walk out together, but when we accomplish something new in our lab, it is so fulfilling for us both. Our partnership develops daily, and it is cool what he can do now!"

Linda, Australia

★★★★★

"The Mastery Program came into my life at the perfect moment - when I was 5 months pregnant. I couldn't ride, but I could walk next to my horse. it kept us both fit. And if you can't walk anymore next to your horse, you can do liberty.So I would say if you are pregnant and don´t know what to do, or think about selling your horse or paying someone else to ride. DON´T. Do ST, and your horse will love you. This program has changed me more than my horses. It is not about making my horse better - making him/her to piaffe or tempo change - it is becoming a better version of yourself. It is more than a way to teach a horse. I love it. When I look at my horses, they are more at ease, relaxed and motivated." 

Anu, Estonia

★★★★★

When Marijke's email landed in my inbox it was a revelation to me! I had been stuck in a rut with my horses. I wanted to learn how to train them as the old masters did, to find an ethical way, to enjoy the time I spend with them. I had studied different books on how to train horses in hand and to teach them to carry me in balance but every trainer only offered part of the story and almost all advice was contrary to the other trainers! Without the benefit of an apprenticeship with an expert trainer I was left out in the cold looking for straight answers. Marijke's online program completely inspired me. I could finally learn how to do this stuff properly, on my own, with my own horse - and yes it is the real deal!

You don’t have to let that happen!
