Learn about Yin Yoga, the Nervous System and polyvagal theory, deepen your personal practice, and create a foundation to teach Yin Yoga in a nervous-system informed way.
for all levels - limited to 9 spots
This 30H training is open to graduates of the 50H HEART OF YIN Training, Yoga teachers and everyone interested in learning more about nervous-system-informed Yin Yoga. It offers a combination of in-depth theory and nervous system-informed Yin Yoga practice. A balance of technique, understanding, and embodied experience.
Yin Yoga offers a space that is often missing in our fast-paced lives. A space we turn to when we long for rest, restoration, and a deeper connection with ourselves.
The moment we begin a Yin Yoga practice is also the moment we begin to relate to our nervous system in a different way.
As attention turns inward a quieter conversation with ourselves begins - one rooted in listening, sensing and allowing.
This inner state is shaped by the activity of the autonomic nervous system, the way we perceive internal and external signals, and how we interpret them.
In this 30-hour training, we explore Yin Yoga through the lens of the nervous system and Polyvagal Theory. You will learn how to meet your own inner state and the inner state of your students with more clarity and skill, so the practice can become a more reliable resource for regulation.
You will learn the fundamental concepts of Polyvagal Theory and how different nervous system states shape our experience. We explore how Yin Yoga interacts with the nervous system, and how elements of the practice influence activation, downregulation, and and how we experience and respond to sensation. We also look at fascia and key receptors, and how long-held shapes influence how sensation is experienced in the body.
This part is about understanding your own nervous system. Through guided reflection and exercises based on the polyvagal framework, you’ll begin to learn about your nervous system's tendencies. You’ll create a personal nervous system map and discover your anchors for regulation that support you in your own practice and life and in holding space as a teacher.
Here we will look at Yin Yoga poses in detail - exploring target areas, variations, and ways to adjust poses for different bodies. You will also learn how to practice step-by-step in a nervous-system informed way and understand what factors contribute to the poses being more calming or activating - offering a clearer understanding of how to guide a practice.
In this part of the training, you will learn breathing techniques, meditations, visualizations and somatic exercises complementary to the Yin Yoga practice that support nervous system regulation.
This part focuses on shaping Yin Yoga classes in a way that supports a sense of safety and connection. You learn to teach from a polyvagal perspective, understanding how your presence, language, and the way you hold and guide a class influence the nervous system. We will also explore how to use touch in Yin Yoga.
The Yin Yoga Teacher Training in Mallorca was truly a transformative experience for me. I learned so much, not only about the philosophy and practice of Yin Yoga, but also about how it influences the human body and mind in such a gentle yet profound way.
The location, surrounded by nature and far from distractions, created the perfect space to slow down, reflect, and reconnect. The food was absolutely delicious and nourishing, and the group energy was warm, supportive, and inspiring. It felt like a little community from day one.
I left this training feeling grounded, inspired, and grateful. I can only recommend it to anyone looking to deepen their Yin Yoga journey and experience true stillness and connection. Thank you Sonja!
Katharina, HEART OF YIN Training Graduate Mallorca, October 2025
I had an absolutely wonderful time - Sonja’s retreat and training were truly exceptional. You could feel in every moment how much love and care went into the entire program.
In the mornings and evenings we practiced gentle Yin sessions that changed each day, each one devoted to an element like Water or Earth. During the day we had inspiring theory and practice sessions that were not only fascinating but also beautifully applicable to everyday life.
The group was small, harmonious, and from the very first day there was a deep sense of connection. It was such a special, heart-opening experience - full of warmth, insight, and community.
I’m endlessly grateful for it and would do it again anytime.
The location and food were also a 10/10 🤍

The rooms are bright and the traditional stone walls offer coolness from the September heat.
Afternoon breaks can spent by the pool, taking a walk to the local cermics workshops or reading in the shade under a palm tree. There is also the option to book an additional massage.
The kitchenfocuses on Mediterranean cuisine. Vegetarian dishes with plenty of fresh vegetable variations are a core part of the menu.

The nervous system is the foundation of our human experience. Our happiness and the depth in which we experience life and deeply connected with it. Nervous-system informed Yin Yoga is a wonderful tool that can support the nervous system towards regulation.
Sonja started prictising yoga in 2010 and has been teaching Yoga since 2019. Since then, her focus has been on Yin Yoga and offering spaces for people to slow down and reconnect with themselves. Her curiosity led her to train with different teachers, completing over 1000H of Yoga teacher trainings. She then deepened her knowledge on the Nervous System with seveal trainings, starting to weave what she learned into her Yin Yoga practice and teaching.
For the past two years, Yin Yoga has enriched my everyday life and given me a whole new connection to my inner calm and my body. Sonja’s classes are always uniquely profound and have supported me throughout my journey. The training helped me understand why Yin has such a powerful effect on me, and it’s also helping me improve my own routine and share these experiences with others. I can only recommend it to everyone - it was such a valuable and truly enjoyable experience.
Norman, 50H HEART OF YIN Training Graduate February 2025
The Yin Yoga training with Sonja was a beautiful interplay of learning, emotions, openness, and new experiences. The knowledge and practice she shared will be lifelong companions on my path - ones I would never want to be without and for which I am endlessly grateful. Giving the class the space it needs, bringing people together, and creating an environment where positive connection and mutual support are the priority is something truly special - just like Sonja herself, her energy, and the way she shares her wisdom and makes you feel good. I encourage anyone to dare to invest this time in themselves and to place their trust in Sonja. For me, it has been worthwhile in every possible way.
Caro, 50H HEART OF YIN Training Graduate February 2025
Sonja’s Yin Yoga training was incredibly enriching for me. She shared so much profound knowledge about the individual poses, their effects on the body, and the entire history of Yin. The atmosphere and sense of trust within the group were so special that everyone felt safe to show up as they were and continue their personal growth. I would take the training again anytime and hope there will be a continuation one day. :)
