Does this sound like your horse?...
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!

Thousands now use Straightness Training to not only overcome their horse's natural asymmetry but also unlock their true potential

Anna van Rheeden & Super (Indonesian Pony)
"Without ST, our horses would still be unbalanced, muscled in the wrong places, developing navicular disease – but most of all without ST, I wouldn’t have been able to develop myself as much as I did."
★★★★★

Rosan Veer & Ciaran (Mérens)
"I thoroughly believe in ST because I have seen the enormous value it has to offer for riders and horses. ST has changed many lives and even saved the lives of horses who were given up on."

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:
- Watch the exercises in your library and read the tutorials.
- Put the theory into practice with your own horse.
- Record a quick video—no need for perfection, just capture your progress.
- 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?

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!"

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!"
