Michael Fritzke & Ton Voogt

Known in the industry simply as The Boys
Where classical lineage meets the science of how the body actually works.

Trained by Romana Kryzanowska as among her last apprentices, Ton and Michael carry the original lineage. But what makes them truly exceptional is what they built on top of it.

A profound understanding of functional anatomy, spiral dynamics, and movement efficiency — applied without ever leaving the intelligence of the classical work behind. They don't modernize Pilates. They illuminate it.
Twenty years of learning

What they taught me to see.

I met Ton and Michael in 2006, at the very beginning of my journey. I was curious, hungry, and looking for teachers who could help me understand not just what to do — but why the body does what it does. What started as mentorship became something much closer. Over twenty years, they have been like older brothers to me in this industry.

What they gave me was the ability to see. To look at a body moving and understand the patterns underneath — where efficiency is being lost, where mechanics can be refined, where pain is simply a misunderstanding that can be corrected. They brought joy into the rigor of the method. They showed me that depth and lightness can coexist — that you can take the work seriously without losing yourself in it.

"When a client walks in today, there is no confusion. We can see what is happening, find what is needed, and create movement that is genuinely more efficient — and very often, pain-free."

That clarity is entirely theirs. The confidence I have when facing a complex body, an unusual pattern, a client in pain — that came from twenty years of learning alongside two men who understand the human body at a level that is rare in this industry.

I share this because I want you to have the same foundation. Not through me — through them, directly.

Is this for you?

For the teacher who wants to truly understand what they're seeing.

  • You feel uncertain when a client presents pain, dysfunction, or an unusual movement pattern
  • You want to go beyond choreography and understand the mechanics driving what you observe
  • You're drawn to the intersection of classical Pilates and movement science
  • You want the confidence to say: I see what's happening here, and I know what to do
  • You believe that helping someone move better — and move pain-free — is the heart of this work
Now it's your turn

Learn to see what others miss.

Inside IVA you will find recordings of Ton and Michael teaching — their workshops, their explanations, their way of breaking down the body's logic and putting it back together inside the classical work. You will hear them think out loud. You will watch them teach. You will see what twenty years of refinement looks like in practice.

There is a particular joy in the way they work. A lightness that makes even the most demanding concepts feel accessible. That is part of the gift — not just the knowledge, but the spirit in which it's shared.

I wish you the same revelations they gave me. The moment a body starts to make sense — not as a collection of muscles and exercises, but as an intelligent system you can actually work with — everything changes.

Ton and Michael both teach independently and continue to offer workshops and trainings worldwide. If what you find here makes you want to go deeper with either of them, I encourage you to reach out directly. Get in touch →
