About Thomas – Founder of Crazy Monkey Movement.


I’m Thomas. For a long time, I thought I was the broken piece, especially back when my ADHD went unnoticed, leaving me feeling constantly out of sync. I threw myself into various movement practices and training systems, hoping each would have that missing spark. Eventually, I realized the problem wasn’t me, it was that many methods weren’t built on clear, essential principles. They felt fragmented, like something important was always left out.

So I set out to start from the ground up: exploring how the body and mind naturally connect, then building a practice that supports every other discipline. That’s how Crazy Monkey took shape, a kind of “root system” that any mover or athlete can draw from. We focus on discovering the why behind each movement, tapping into genuine curiosity, and creating a space that celebrates the uniqueness of every participant.

Today, I’m based in Lisbon, sharing Crazy Monkey’s blend of biomechanics, mindfulness, and play with people who want more than a typical workout. For me, the best part is watching students realize that their body isn’t a liability, it’s their gateway to deeper awareness and freedom. If you’ve ever felt like you don’t quite fit into the standard fitness mold, I invite you to give Crazy Monkey a try. Because once you align with those first principles, you’ll see just how limitless your movement—and your life—can become.

— Michael Holleman

I was born in Leiden, Netherlands, and my passion for movement started with football. Studying Sport Studies in Amsterdam gave me a broad foundation in different athletic disciplines, from team sports to martial arts and endurance training.

Early in my journey, I came across Movement Culture. I threw myself into every opportunity to get involved and learn about this phenomenon that inspired me so much.

I joined Crazy Monkey as an intern in 2017. Together with Thomas I developed Crazy Monkey Philosophy. It brings together everything we have learned from years of training and experimenting with different movement styles. What started as an idea has grown into a practice that continues to evolve and now reaches people online as well.

For the past eight years I have been teaching classes daily and giving workshops  for companies like Nike and Jumbo, but mostly for people looking to deepen their practice. I love seeing how movement can change the way people feel, think, and live.

Crazy Monkey is my way of sharing that. I want to create a space where people work hard, have fun, and discover what they are capable of. Movement to me isn’t just physical, it is a way of being.

I live in Leiden and commute to Amsterdam every day where I continue to develop Crazy Monkey. My goal is simple: to make this practice available to more people because I believe it has something unique and valuable to offer.
