About Maestro

Meet the equine icon behind the global Straightness Training movement"

Marijke's Straightness Training journey started with her horse Maestro, a Dutch Warmblood gelding born in 1994.

Maestro was – in a way – handicapped by his natural asymmetry and the fact that this was not recognized before.  

Therefore he was physically out of balance which caused symptoms such as running and rearing. And this caused him to be also mentally out of balance resulting in a state of flight or fight.

Marijke succeeded in resolving Maestro’s asymmetry problem so that he could he was able to perform comfortably in all that he was asked to do.

With this special horse, Marijke started to travel the road of Straightness Training that lead the combo all the way to performing the levade. 

The levade is perceived as the summum of Straightness Training: It's about balancing the horse on two legs, asking the springy hind legs to carry all weight instead of the already naturally heavy front end.

About Straightness Training

A path to achieve balance in body, mind, heart, and soul 

Maestro and Marijke traveled such a long road, and what an absolute privilege it is to share this journey with other riders and help them turn things around for their 'ordinary' horse and reach much higher and 'extraordinary' levels.

To pass on the ST wisdom and experience to other horse owners – who might even struggle with their own 'Maestro' – is very special.

Straightness Training is not only for the high and mighty in dressage.

It is for everybody - it doesn't matter if you are a beginner or advanced rider.

And it's for every horse - no matter what age, breed or size.

The goal of ST is to have horses fit in body, mind, heart, and soul into late life.

And in case you want to ride our horse: to give your horse the best possible physique to carry you no matter their conformation.

Tthe challenge of Straightness Training is not about having the best moving horse...

but instead, to get every horse, we ride to move as well and in the most healthy way as he possibly can!

About the ST movement

An international community of difference makers & game changers

In 2004, we realized that many more riders and horses could be helped and reach much higher levels than they now expect to be capable of!

This made us decide to start the ST movement in the Netherlands to inspire people to do the things that inspire themselves and their horses.

In 2009, we began to share our thoughts, insights, and experiences through online videos, eBooks, articles, memberships, and clinics also in English. This way we could teach people all over the world about the meaning and usefulness of the various gymnastic Straightness Training exercises to rebalance their horse.

With our international website, we served riders anywhere in the world who wanted to discover everything about natural asymmetry and Straightness Training in order to help their horse flourish in body, mind, heart, and soul.

But it was not enough.

The high demand for education and training in Straightness Training inspired us to create The ST Academy which now has thousands of members across the world.
