Use The Power Of Self-Mastery

After 7 years of experience with the Straightness Training Academy, with thousands of enthusiastic Mastery students, we'd like to take it a step further!

We're very proud of our Straightness Training students and their results with their horses, and it's our ambition to increase our impact even more! To be even more life-changing! No matter the level of skill or the age of our students!

We'd like to take the fundamental work with horses to a higher level by not only focusing on mastery of Straightness Training but also on mastery of oneself.

In the words of Leonardo da Vinci (1452-1519):

❝ One can have no smaller or greater mastery than mastery of oneself ❞

Leonardi da Vinci was a so-called "Renaissance Man", which is a person who is an expert in a wide range of different subjects and areas of wisdom. The reason why he mastered many crafts was that he used his full potential.

He used the power of self-mastery.

Make The Most Of What You've Got

Leonardo da Vinci and other Renaissance Scholars had a growth mindset and focused on developing their capacities in body, mind, heart, and soul as fully as possible at any age. Thanks to a balanced body, a curious mind, an open heart, and a peaceful soul, mastery in any other aspect of life was much easier.

In the ST Academy, we apply this wisdom to help you become the good horse trainer that you're meant to be. 

We use the power of self-mastery to grow your ability to make the most out of your physical, mental, emotional, and spiritual health so you can actualize your potential. 

Unlock Your True Potential

Self-mastery not only develops you as a human but also gives you the ability to be successful in Straightness Training. 

Self-mastery helps to create a vision for your future self and to find meaning in challenging times. 

Through self-mastery, you can break through resistance.

You learn to master yourself by getting out of your own way.

Through self-mastery, nothing is holding you back!

Go Out Of Your Own Way

The ST Academy is designed to assist you on your personal path to mastery.

You've barely scratched the surface of what you can achieve, and you know it!

But my guess is, since you're reading this, you're ready to change all that.

Whether you're a total beginner, an ambitious leisure rider, a professional horse trainer, an equine therapist, an instructor - whoever you are, and whatever you do, there's one thing that's certain:

You are ready to become a next-level horse trainer.

Like a true Renaissance rider who is clever at many things, who keeps learning and growing to become the best version of oneself. 

Ready To Change Your Life? Let's Go...

In the Scholar Programs of the ST Academy, you can find your own personal freedom, and become this next-level horse trainer by 'training' oneself in the spirit of the Renaissance men and woman.

These Renaissance Scholars strived for constant and never-ending improvement in their body, mindset, emotions, spirit, crafts, skills, and many other areas of their life to be able to create things of beauty and worth.

No matter how much doubt you currently have, you can truly change yourself, and create lasting change for your horse.

You just need a different approach.

Therefore, every month, you'll get new insights and resources on topics like:

  • Overcoming Obstacles
  • Feeling Better
  • Getting More Done
  • Creating good habits
  • Developing Confidence
  • Getting Your Mojo Back
  • Starting Over
  • Keeping Momentum
  • Staying Focused
  • Getting Results
  • Finding Meaning
  • Making Impact

Start your transformation now to living a better quality of life, and reach long-term success. 

How Does It Work

The three Scholar Programs in the Straightness Training Acdemy are designed to help you transform into the good horse trainer you're meant to be so you can turn your (difficult) horse into a dream horse!  

1. The PRIMARY Scholar Program

This program is for you if you're only interested in 'cognitive' mastery. In this program, it's about gaining knowledge and mastering the theory of Straightness Training. As a Primary Scholar, you'll EXPLORE the world of self-mastery and Straightness Training on an intellectual level. Each month, you'll get access to the following resources:

2. The PREMIUM Scholar Program

This is THE place to be for riders who'd like to put the theory into practice, and strive for 'physical' mastery. In this program, it's about learning to do the right things and to do things right. As a Premium Scholar, you'll EXPERIENCE self-mastery and Straightness Training on a deeper, experiential level. You'll receive all the monthly resources of the Primary Scholar Program, PLUS, you'll get access to:

3. The PRIVATE Scholar Program

This is a program for riders who are no longer a beginner in Straightness Training, and have been a Premium Scholar for at least 6 months, plus, have achieved at least Grade 1 in the ST Evaluation Program. As a Private Scholar, you'll be able to EXCELL in self-mastery and Straightness Training.

HOWEVER, this membership will most certainly not be for everyone... only if you are at the point where you want to get the next level and accelerate, and are ready to empty your cup, treasure your beginner's mind, and are willing to use the two magic powers that fuel success, than this might be the Scholar Program for you.

As a Private Scholar, you'll get access to the resources of the Primary AND Premium Scholar Programs, PLUS, Marijke will coach you personally with:

All Scholar Programs Include Access To the STclopedia

The encyclopedia of Straightness Training helps you learn the skills, strategies & tools you need to actualize your horse's full potential in body, mind, heart, and soul. 

As a Primary, Premium, or Private Scholar you get access to this STclopedia, and to avoid overwhelm, we will serve it into bit-sized chunks in the form of monthly Mastery lessons so you know exactly where to start and what to do next.

The STclopedia is broken down into 12 Mastery Modules with Lessons with supporting video content and complementary manuals on how to do groundwork, longeing, work in hand, riding, and Straightness training at Liberty.

Every month you get access to another set of Mastery Lessons that will help you fast-track your growth, achieve extraordinary results, and save you years of time-consuming trial and error.

See What Premium Scholars Have To Say About The Most Popular Option:

 Joining the Premium Scholars program, has been a game-changer for me. In the Premium Scholars, I have had the opportunity to submit Hotseats, Breakthrough videos, and a Touchstone each month. This ‘cycle’ has given me quick feedback on my progress and advice on what to focus on improving. Marijke is an amazing coach and hones in on our key problems instantly. 

I have also received fabulous insights into the training of others, at all stages of their journeys!

Keeping an eye on the essence and mind on the muscle is my new mantra, and I look forward to where the next levels of Straightness Training will take me and my horses.

~ Sarah Orr, Scotland

❝ In July 2020, I joined Premium Scholars and I decided to go all-in with the monthly ‘cycles’ – including Self Mastery live classes, Hot Seats, Breakthroughs, Mastermind sessions, and then a Touchstone at the end of the month.

The Premium Scholars use slogans like “Fail-Fast-Forward” and “5-4-3-2-1-Go”. Getting into the routine of filming and sending in snippets of our work and getting the direct and immediate feedback from Marijke is spinning the learning cycle faster for me, so it has taken my ST-journey to the next level.

When I first started my ST journey, I made a notebook just for this, and on the front of it says “Keep up momentum”. I did not know how true this was and how important a motto this would be. Keeping up momentum it so very hard when you are the only one in your area doing it, so the Premium Scholar Program has been the support I needed to do just that. ❞

~ Hanne Friberg, Denmark

"The live classes are hugely helpful and insightful with so much to take away from everyone’s videos. It is so helpful to watch all the different Hot Seats and Breakthrough sessions, and see where similar problems arise, and all the amazing progress."

Gina Peasnall

"I love the community, and also seeing other like minded students working with their horses. I like that there are goals in place each week to work towards, otherwise it is easy to float along and not get results. I also like that you can get feedback immediately and not keep on practicing incorrect work. Everything is always explained so well and the program works very well! "

Louise Binge
South Africa

"It's great to see evryone's progress and the power of 2mm changes and how these are compounding month on month. This programme is so powerful with these regular opportunities for feedback."

Oakwood Meggie
United Kingdom

"My biggest take away is how much everyone was improving. We are all so much better at filming, at writing out our questions, at taking notes, at working things out. Our learning curve is steep. I learn so much from each person and my notes are invaluable and I reread them often."

Victoria Smith

"The Hot Seat and Breakthrough Sessions are fantastic, I have learned so much seeing the videos of other Scholars and hearing the feedback from Marijke. "

Here's What You'll Get When Joining The ST Academy

Whether you are just starting out, or want to take your advanced skills to new heights, the ST Academy can help by providing crucial elements vital to your success!

Join the ST Academy To Help Your Horse - And Make A Measurable Difference To Other Horses Too!

When you invest in your success through the ST Academy, you're not only helping your own horse, but you're also helping other horses in need. 

We believe that animals need to be treated with respect, love, and care. Especially the over 100 million working horses, donkeys, and mules who provide invaluable support to the daily life of an estimated 600 million people in some of the poorest places in the world through transportation and production. Healthy working horses, donkeys and mules help to put food on their owner's tables, send their children to school, and build better futures for themselves and their families. 

Our goal is not only to help you make a positive change for your horse but also to make a positive difference for horses, donkeys, and mules in need. That's why a portion of profits from our company go directly to non-profit organizations that support horses, donkeys, and mules in need.

Frequently Asked Questions

The ST Academy is geared for big-hearted horse lovers, novice riders, ambitious leisure riders, advanced horse trainers, and instructors.

It’s for committed beginners and evolving professionals, and for anyone who wants real change.

Many Scholars join to get to transform their lives, to take things to the next level, to achieve their goals, and to feel more empowered overall.

It's for everyone who'd like to get strategies and tools to take their work and their life from good to great!


  • The Primary Scholar Program helps you to explore the world of Straightness Training and self-mastery. It helps you to intellectualy understand what needs to happen, why and how, which help you achieve cognitive mastery. 
  • The Premium Scholar Program is a THE place to be to put the theory into practice. It helps you to experience the world of Straightness Training and self-mastery from the inside out. It helps you to practically experiment with what needs to happen, which gives you emotional and physical mastery.
  • The Private Scholar Program is for advanced riders who wants to get their work to the next level. It helps you to excel in the world of Straightness Training and self-mastery. 

From 2013 until 2020, our yearly class was designed as a year long coaching program.

As of July 2020, you can enjoy coaching for as many months as you'd like with the Scholar Programs

Some Scholars will decide to stay in the program for years. Others decide to join for just a few months.

There is no minimum enrollment time, but we know you'll find so much value, you won't want to go.

You can cancel your membership any time, and keep all the downloads... but you won't want to once you start seeing your life change. Simply choose one of the Scholar Programs, and let's get you started. See you inside!

Think about it this way:

Would it be worth 8.61 euro a day for you to come spend time hanging out with me and looking over my shoulder, me helping you..…

...having me walk you through every step, every module, video, manual, framework, concept, strategy, technique, concept, me personally showing you what’s working best and helping you deploy it with your horse.

Well, the videos, manuals, group classes, and video evaluations are meant to give you that same experience!

For example, you show up on in a mastermind session, you say here’s what I need help with, then I walk you through it:


We figured it out together!

Or with your video review, where you’ll get your most important 2mm pointed out:


Another breakthrough!

So I’m giving you the real deal, where I'll tell you "here’s exactly what works, what to do when it doesn’t work out, here’s what to focus on, here’s what to avoid"...

... for only 8,61 a day.

I got on google and I did a search on google for what can you buy for about 8,61.

The best answer I found was a big bag of horse treats.

So what would you rather have?

365 bags of horse treats ... (and a spoiled horse probably at the end of the year) ...

Or a ready to go horse training program created by me personally?

So 8,61 euro is the daily cost for being a Premium Scholar.

8,61 less a day is probably not going to change your life, but the work we do together can change you and your horse for sure!

Together we can do great things!

We’ll work together as a team in your development, towards YOUR goal and the results YOU seek, at your own level - it doesn’t matter if are a beginner or an advanced rider.

And you can train at your own pace, in your equestrian discipline, suitable with your ambition, and your personal situation.

I look very much forward to start working together, because I believe in you and your horse, I believe in this program, and I believe that together we can get far!
