What to expect

I've been teaching Core Concept Training at Tribes for years, and those nine(ish) o'clock Sunday mornings have become something very special to me. A familiar moment in the week, with familiar faces, new people joining, and space to discover something different each time. We've shared so many mornings together, and I don't think I've ever really put into words how much that means to me.

Tribes has been my playground for ten years. A place where I've been able to try things, make mistakes, change my mind and keep learning. About movement and running a business, but also about myself: who I am, what matters to me, and what I want to share. So much of my own growth has happened here, alongside you.

Sharing movement is one of the ways I feel most connected to other people. There is something about being in a room together, moving, exploring and feeling things in our own bodies, that I find difficult to put into words. I need that exchange as well. I might be the one teaching, but those Sunday mornings give me so much in return.

Core Concept Club is a celebration of all those mornings and everyone who has been part of them. We'll take time to explore the flowing, integrated movement that has grown with us over the years, discovering the core in new ways and feeling how it connects throughout the body.

How to book

For our 10-year anniversary, we’re hosting a weekend of beautiful, specially created classes, with a few surprises along the way to thank you for being part of Tribes.

Book as you would any other open class, using your membership, class card or pass. Spots are limited, so book early!

Please be mindful when booking: for this weekend only, we’re using a 12-hour cancellation window. You can cancel free of charge up to 12 hours before your special starts. If you can’t join us, cancelling in time gives someone on the waiting list enough notice to take your place and helps us avoid empty spots. A €7.50 fee applies to late cancellations and no-shows.

All classes have a waiting list. If a spot becomes available, you’ll receive a message and have 60 minutes to claim it.

True movement can't be separated from the moment it's made, and everything the dancer feels in it. Without embodiment, movement becomes mechanical, an empty shell. I love observing the differences between people and bringing a body to the point where it clicks and moves freely.
