Marijke de Jong's Straightness Training Academy

Enroll as a Scholar & Get Access To The STclopedia

The encyclopedia of Straightness Training helps you learn the skills, strategies and tools you need to turn your difficult horse into a dream horse!


Here's How We're Going To Work Together:

The Scholar Program in the ST Academy include access to the Mastery Program. As a Scholar, you'll also get access to the Evaluation Program. As a Scholar, you can be invited to the ST Instructor Program once they have reached a certain level in the ST Evaluation Program.

Optimize your Knowledge and Skills with the Monthly Mastery Lectures

The STclopedia is broken down into training modules, sections, and lessons with supporting video content and complementary manuals. These course materials will help you fast-track your growth, achieve extraordinary results, and save you years of time-consuming trial and error. Monthly Mastery lectures will take you by the hand and walk you through the entire STclopedia, STep by STep. Every month, you will receive a Mastery Lecture of the Month in your library with one or more lessons in the following topics:

Getting STarted

Whether you want to take your existing skills to new heights, start your youngster, keep your senior going, or you're just starting out, the 'Getting Started' Module will set you up for success and give you a kick STart.

It teaches you where to STart and what to do next, and all 'how-to' materials about the ST exercises are easy to understand, and more importantly, easy to put to use right away!

Every month, you'll get another set of lessons in the other Mastery Modules - this way you don't get overwhelmed by all the lessons, videos, manuals, and other course materials, and you never get the feeling of "getting behind"! 

Every Masterpiece Has A Solid Foundation

After the kick STart, we will help you create a long-lasting solid base on which you always can rely on:

  • You'll clarify the vision you have for you and your horse and set inspiring growth goals.
  • I'll also help you harness your unique strengths, personality, and skills to become the best you can be for your horse.
  • I'll show you how to map the natural asymmetry of your horse to create a fitting strategy to straighten your horse.

By the end of this Mastery Module, you'll have a rock solid foundation and a clear action plan to take the training with your horse to new heights. 


Get The Right Tools & Use Them Right

The cavesson is the ultimate tool to help us with Straightness Training. We use it to gymnastize our horse in groundwork, longeing, work in hand and riding. 

In this Mastery Module, you'll learn how to choose the right tools for your training sessions, and how to use them in an effective and efficient way, so you do the right things and do things right. 

Preparation Is Key - Think First, Act Later

We will cover the aids in a several Mastery Lessons, so you'll master all the aids we use in ST. I will show you:

  • The different types of mental and energetic aids.
  • How to use your body language and voice cues.
  • The difference between observing and producing seat, leg and rein aids. 
  • And we will unravel all mysteries about the magical 'half-halt' which is a key element in rebalancing your horse. 

You learn exactly when, where, why, and how to use all different aids.


Horse Training 101

In this Horse Training 101 lessons, you'll discover the general spectrum of strategies and techniques on how to train horses.

This course is perfect for beginner horse trainers because we'll start from scratch. You'll learn the basics of how to communicate and interact with your horse, how to teach your horse completely new things, and how to motivate and inspire your horse. For sure advanced riders will discover some interesting 2 mm in this course that they forgot about, or that they see now in a completely new light. Often huge  results come from small changes and refining little details.

Set Yourself Up For Success in the Other Training Pillars

In the Groundwork lessons, we're going to put down a solid practical foundation with the use of a cavesson and a line. You'll also:

  • Understand what exercises you need to use to counteract your horse's natural asymmetry.
  • Discover the right (and wrong way) to stretch your horse's body to both sides.
  • Learn to use the most effective and easy-to-use exercises to strengthen the hindquarters and ease the fragile front legs.

No matter what skill level, at the end of the basic Groundwork lessons, you'll have everything you need to get STarted in the riding arena! Along the way, you'll also widen, broaden, and deepen your work with the more advanced exercises.

The Tricks of the Trade

In the Longeing lessons, I will teach you the fine details and 'magic' stuff when it comes to longeing. 

These lessons teach you:

  • How to stretch, contract and relax muscles in walk, trot, and canter.
  • The best approach to make your horse fit and flexible.
  • How to deal with challenges, for example, if you can't get your horse away from you.

By going through the Longeing Lessons, the invisible gets visible, and the untouchable becomes touchable, so you know exactly how to get the job done.

Build The Bridge To Riding

The Work in hand lessons are all about doing all exercises with a bridle, with or without a bit, whatever you prefer. And we will take it a step further with the exercises:

  • We will not only use exercises where the horse is bend towards us, as in shoulder-in and haunches-in, but also away from us, as in the renvers. 
  • We will deeply cover the 'reason why' behind all exercises so you can do them all with essence and don't end up with 'look-a-likes'.

By going through the Work in hand lessons, you learn exactly what to do to strengthen your horse even more, so your horse can carry you properly. 

Become The Best Rider You Can Be

There's a whole series of lessons about the art of riding. It gives you the full insights into the why, what, and how of all riding exercises: 

  • The circle
  • The shoulder-fore and shoulder-in
  • The haunches-in, renvers, half pass, and pirouette
  • In a normal tempo in walk trot and canter.
  • And in collection - all the way up to the school walk, the piaffe in trot, and pirouette in canter.

Through clear videos and comprehensive manuals, you are able to study everything in detail, so that you are well prepared to start riding.

More With Less

ST at Liberty is the magical ingredient that will help you:

  • To reach more with less guidance.
  • To resonate and synchronize with your horse.
  • To achieve complete harmony, togetherness, and oneness with your horse.

In this connection, you will find your horse focused, interested, and strongly motivated in learning and doing all ST exercises. And then you will experience that all other four training pillars will work better for you as well!

With a proper preparation and regular practice in all five training pillars, your horse will start to look great and feel amazing!

Philosophy Helps To Work Independently

"ST is for the horse, the horse is not for ST" will be the foundation of our philosophy. We understand to be understood and teach according to the principles "Observe first, produce later" and "Think first, act later". We let things arise organically and strive for constant and never-ending 2mm improvement. We never lose sight of the essence and strive for quality over quantity. 

In the Philosophy lessons, you'll learn to put these fundamental concepts and many other core ideas into practice and help you to train with clarity and confidence so you can work independently.

From Hands-on to Online

The recordings of live lessons I gave during Mastery clinics in the Netherlands, the UK, Sweden, the USA, South Africa, and Brazil are super packed with demos, case studies, theory sessions, and practical lessons with amazing people and horses.

By watching these lessons you can get even more ideas and inspiration to fine-tune your own work.



What Can The Mastery Modules Do For You?

Getting your horse happy and healthy and becoming the good horse trainer you're meant to be requires clarity, confidence, vision, and the ability to take action on a consitent basis on the right STrategies.

Without a roadmap and STep-by-STep guidance, the process can be overwhelming.

The ST Mastery Lectures can save you years of unnecessary suffering and time-consuming trial and error.

Our primary goal is to train you to think, act, and interact like an allround horse trainer, so you have skills that serve you for life.

We already helped thousands of riders across 50+ countries, and we'd be honored to work with you too!

And to make the STclopedia even more effective, here's something else we've got for you:
