Sanctum is a fitness experience with a cult following. Founded during the pandemic in Amsterdam, it combines elements of HIIT with kundalini yoga, martial arts, animalistic flow, breathwork and primal fitness. It’s curated to music inspired by the city’s electronic scene, enhanced by spoken word and elevated with orchestral pieces to complement mindful and meditation movements.
As Sanctum’s global rollout gains momentum – including partnerships announced with Six Senses and Auberge – Spa Business’ Liz Terry catches up with co-founder Luuk Melisse.
What’s the elevator pitch for Sanctum? It’s a cathartic, spiritual mind/body experience where we combine ancient methods and philosophies and mix them with their modern equivalents.
We created a signature workout sequence, which is a combination of high-intensity movement, kundalini yoga, martial arts and the power of the mind and created a multi-sensory immersive experience around it.
Our workouts are delivered in unique locations all over the world, such as churches, ancient ruins and beaches. The spaces are filled with candles and the fragrance of sage smudge sticks, which are used in shamanic tribes to clean spaces – it smells delicious.
Everybody wears headphones and through those, they’re hearing a rollercoaster of motivational music, soundscapes, poetry and wisdom. We also work with binaural beats and healing frequencies.
Tell us about your instructors I have a background in theatre, so we often have dancers and actors on our team.
This is because I can train people how to move, but the magic we seek comes from them being an inspiration and being gifted in storytelling and this makes the role ideal for people who’ve trained in the creative arts.
We call our instructors guides because they don’t tell people what to do. I’ve created a signature framework – which we teach in an intensive three-week programme – and they then build on this by sharing their own personal, authentic stories.
People don’t remember the number of squats they did, but they remember a personal story or advice about letting go or a dive into spirituality. This is the magic of Sanctum.
Music is a key part of Sanctum – tell us more We’re the world’s first movement class to incorporate sonic branding. This has been created with Myndstream – which is part of the company that does music for Stranger Things and Bridgerton – and we use it in our classes and online.
We create classes where the storytelling, the music and the movement come together in one experience.
What’s the science behind the headphones? Berkeley University researched why people cry more on a plane when watching a movie with headphones than when they watch it on TV and found that when people listen through headphones, their brain perceives the sound as though it’s their own voice and this heightens their emotions.
This means that when people are in my class, I have a conversation with each of them inside their heads. That’s what makes it so intimate.
What’s special about Sanctum’s approach? Our main goal is emotional release and to alter body frequencies. We believe people experience by doing, so we don’t over-explain.
Tomorrow, for example, I’m doing a class around love. It will include an intro talk accompanied by a soundscape at 528 Hz, which is the frequency of love and kundalini heart openings to activate the energy centres in the body – but I don’t spell out these steps. Part of the magic is bringing a number of elements together for people to find out things themselves.
What’s your personal story? I used to be a dancer, my mum was very spiritual and my dad is a business guy. I brought those elements together and started travelling the world to acquire more knowledge of spirituality and different philosophies.
I enjoyed discovering practices and beliefs that are thousands of years old, such as kundalini yoga and qi gong, that work with body energy and I began to weave these into a new modality.
Doing it, I felt the release that I had as a dancer because we use our body as a vessel to express ourselves.
I started Sanctum as a mindful fitness concept, however, I now realise it’s more of a ritual. The community aspect has also emerged as the main pillar.
We live in a world with more than 7 billion people, yet loneliness is one of our biggest diseases. Sanctum has, very organically, become a safe space where people can laugh and cry and be themselves but with each other.
Where can people experience your classes? We started in Amsterdam and host daily classes in the most beautiful churches and other spiritual spaces. Earlier this year, we launched our sessions in London.
The US is very much on our radar for 2025 and the rest of Europe is also in our sights.
What rates do you charge for your sessions? In London, £40 (US$52, €48) a class and in Amsterdam €25 (US$27, £21) – it’s a different market and very competitive.
We want more people to be able to experience it, so we don’t want to make it too expensive. Our private retreats are more high-end.
Tell us about the retreats We work with hotels to create three or four-night retreats which have daily Sanctum experiences at their core.
We focus on nature and use the story of the place in the class, so we might do them on a beach in Ibiza or in the ruins of Rome, where we create classes based around the Roman gods.
We partner with holistic experts to deliver wellbeing with an edge – for example, we might do a cacao ceremony or use a DJ who creates music by tapping into the electrical impulses in plants.
We also work with experts in energy and integration, such as breathwork and sound healing. Then there are social elements as well as a focus on stillness – organising things such as journaling workshops.
When we create a retreat, we want to take people through all the spectrums – high energy, low energy, going within themselves and reaching out to others.
Who are your retreat partners? In Europe, we’ve collaborated with Six Senses in Ibiza and Switzerland and we also took part in the Soneva Soul Festival in the Maldives in October. In the US, we’ve collaborated with Auberge and delivered four retreats there in 2024.
What do they cost? It depends on the property, but as a guide, they’re priced between €3,500 (US$3,845, £2,935) to €5,000 (US$5,492, £4,194) for four days.
You’re also doing mega events... Our biggest event concept – called the Frequency Festival – sees 2,000 people taking part over 2.5 hours, so the energy is off the charts. We’ve just held festivals at the Olympic Stadium in Amsterdam and The Beams in London.
What are your dreams for the business? We want to make Sanctum a global movement to help people get in touch with themselves and others in order to live their best life and make the right choices.
We really need this in the world right now. We need more love and connection.
Often, when I leave a fitness class in a gym, I leave stressed because it’s about the ‘beach body’, it’s about ‘bigger biceps’. It’s very aggressive and that is what we really didn’t want to do when we were creating Sanctum.
We’re a disrupter and we’re always trying to work out how we can create something different.
