300-hour Advanced yoga Teacher Training
Yoga Alliance Credited
With lead trainers Sarah Emilie Boas, Nicolai Boas, Cédric Gorinas, Leah Wrobel & Guests
Our 300-hour Advanced Yoga Teacher Training is designed for teachers who want to deepen their knowledge, refine their teaching, and develop the skills to confidently teach advanced yoga in a wide range of settings.
Primarily taught by Nicolai Boas, Cédric Gorinas, Sarah Emilie Boas & Leah Wrobel the training explores advanced biomechanics and physiological understanding, asana technique, sequencing, breathwork and meditation, alongside an in-depth exploration of applied yoga philosophy, trauma informed practice and self-study.
A strong focus is placed on teaching methodology, teaching technique, mentoring, personal growth and shadow work. We develop the practical skills needed to design and teach advanced yoga classes, private sessions, events and retreats, while exploring how to communicate effectively, make informed teaching choices, and adapt your approach to specific groups and individual needs. Alongside developing teaching skills, the training offers space for deeper self-inquiry, personal development and embodied exploration.
The training also introduces the foundations of Ayurveda and yoga therapy, while special guest teachers are invited to share their expertise and offer additional perspectives from within and beyond the traditional yoga framework.
This is a training for teachers ready to go deepen - not only into the practice of yoga, but into the craft, responsibility and creativity of teaching it.
Who can join?
This training is for yoga teachers who already have a foundational understanding of yoga and are ready to deepen their knowledge, teaching skills and personal practice. To join, you should have completed a Yoga Alliance–certified foundational teacher training or an equivalent education, and preferably have some experience teaching basic yoga classes.
You do not need to belong to a particular yoga tradition or teaching style, nor do you need to have an advanced or highly physical personal practice. What matters is a genuine curiosity to explore yoga more deeply, develop your understanding of the body, mind and practice, and grow as a teacher.
The training is suitable for teachers looking to expand their teaching beyond the basics, develop greater confidence and precision, and explore how to work with more advanced students, private clients, groups, events and retreats.
Training Dates
& Details
Module I
March 5th - 12th
Foundation Retreat
Lead by Nicolai Boas, Cédric Gorinas & Sarah Emilie Boas
The training begins with a 7-day residential retreat in Gudmindrup, bringing the group together to establish the foundation for the journey ahead.
We know that participants will arrive with different backgrounds, experiences and approaches to yoga. The retreat is therefore an opportunity to create a shared foundation and develop a common language and understanding that we can build upon throughout the training. Through practice, teaching, discussion and exploration, we will begin to find a coherent common ground while still allowing space for the individual perspectives and experiences each participant brings.
Beyond establishing the academic and practical foundation of the training, the retreat is also about connecting as a group. Spending seven days together creates the time and space to get to know one another, build trust and create the community that will support the training throughout the year.
The retreat is an all-inclusive residential stay, with accommodation, meals and the full retreat programme included.
The retreat is a full immersion, with a full programme of teaching, practice, and study each day.
Beginning: Friday the 5th, check-in between 13:00–15:00
End: Friday the 12th, concluding at approximately 13:00
Module II
April 2nd, 3rd & 4th, April 23rd, 24th & 25th
Technique & Applied Physiology and Anatomy
Lead by Nicolai Boas
The first module runs across three weekends, with teaching on Saturdays and Sundays from approximately 9:00–18:00. The module is designed to deepen your understanding of anatomy and physiology in relation to yoga, while developing the ability to apply this knowledge in a practical teaching context.
We will explore the body and its systems in greater depth, building on the anatomical foundations of a basic teacher training and developing a more nuanced understanding of movement, biomechanics, physiology and individual variation.
A central focus is learning how to translate this understanding into teaching: how we can observe and work with different bodies, adapt techniques and approaches, and make informed choices depending on the individual, the group and the style or intensity of practice being taught.
The aim is not simply to know more about anatomy, but to develop the tools and confidence to use anatomical and physiological understanding as an integral part of intelligent, adaptable and inclusive teaching.
The second module takes place over two weekends at the studio in Vesterbro, with a full programme of teaching, practice, and study across all six days.
Schedule: Friday–Sunday, both weekends, 09:00–18:00 all six days.
Module III
May 14th-17th
Advanced Sequencing
Lead by Nicolai Boas
Over four days during the Pinse holiday, we will explore how to expand and refine your sequencing skills, developing greater creativity, adaptability and freedom in your teaching.
We will work with the principles behind creating thoughtful and engaging classes across different styles, themes and levels of practice. Rather than relying on fixed formulas or predetermined sequences, the focus will be on understanding how to build practices that have purpose, progression and coherence while still leaving room for creativity.
A central part of the module is developing the ability to teach more freely — to move beyond simply remembering a sequence and instead respond to the room, the students and the moment. Through exploration and practice, we will work towards greater confidence in making choices, adapting sequences and allowing the teaching to unfold more organically.
The aim is to give you both the tools and the freedom to create intelligent, creative and inspiring practices for a wide variety of students and contexts.
The third module takes place over four days at the studio in Vesterbro, with a full programme of teaching, practice, and study each day.
Schedule: Four days, 09:00–18:00 each day.
Module IV
June 4th-6th
Trauma Informed Yoga
Lead by Leah Wrobel
This module explores the principles and practices of trauma-informed yoga, inviting us to consider how an understanding of trauma can deepen and reshape the ways we teach, communicate, and hold space for practice.
We will explore how trauma can shape our experience of the body, nervous system, emotions, and our relationship to movement and the world around us, and how yoga can offer opportunities to cultivate safety, autonomy, choice, and a renewed sense of connection with oneself - creating conditions that may support healing.
A central focus will be on developing greater sensitivity to the diverse needs and experiences students bring into the room, while cultivating greater awareness of our therapeutic presence and our capacity for compassion and attunement. We will explore language, sequencing, boundaries, choice, and thoughtful adaptations, learning how even subtle shifts in our teaching can make a meaningful difference.
The intention is not to turn yoga teachers into therapists, but to deepen our capacity to teach with awareness, empathy, and discernment - offering practical tools and a more nuanced understanding of how to create yoga experiences that are safer, more accessible, inclusive, and empowering.
The fourth module takes place over three days at the studio in Vesterbro, with a rich programme of teaching, embodied practice, reflection, and study each day.
Schedule: Three days, 09:00–18:00 each day.
Module V
September 10th-12th & September 24th-26th
Meditation & Breathwork
Lead by Cédric Gorinas & Sarah Emilie Boas
This two-weekend module offers a deeper exploration of breathwork and meditation, with a focus on developing both personal practice and the ability to integrate these tools into teaching.
The course runs from Friday 15:00–18:00 and Saturday and Sunday 9:00–18:00 on both weekends. We will explore a range of breathwork practices and meditation techniques, looking at their effects on the body, nervous system and mind, as well as the principles behind working with them safely and effectively.
Through both practice and theory, we will develop a more nuanced understanding of how breath and meditation can be used as powerful tools for regulation, awareness, concentration and transformation. We will also explore how to teach and adapt these practices to different students, needs and contexts.
The intention is to move beyond simply learning techniques and towards a deeper embodied understanding of breathwork and meditation - allowing participants to develop their own practice while gaining the confidence and understanding to share these tools with others.
The fifth module takes place over two weekends at the studio in Vesterbro, with a full programme of teaching, practice, and study across all six days.
Schedule: Fridays 15:00–19:00, Saturdays and Sundays 09:00–18:00.
Module VI
October 25th-30th
Teaching Technique & Exams
Lead by Nicolai Boas, Cédric Gorinas & Sarah Emilie Boas
The final module runs from Monday to Saturday and brings the training together in a final week of practice, exploration and integration.
Throughout the week, we will work with advanced asana technique, teaching methodology and different approaches to practice, while drawing inspiration from a variety of teachers, traditions and perspectives. The focus is on bringing together the knowledge and tools developed throughout the training and exploring how they can become part of each participant’s own teaching and practice.
The week also includes the final examination, providing an opportunity to demonstrate and reflect on the knowledge, skills and teaching abilities developed throughout the training.
We finish the week by celebrating the completion of the journey together with a graduation, marking the transition from the training into the continued development of each participant as a teacher.
The sixth and final module takes place over six days at the studio in Vesterbro, with a full programme of teaching, practice, and study each day.
Schedule: Six days, 09:00–18:00 each day.
