Her passion for movement led her to study several styles of dance in addition to ice-skating, which then led her to teaching and coaching skaters in Berlin since 2007.

She experienced firsthand the benefits of Pilates on the body and the enhanced movement qualities while practicing whatever sports she chose. Following her desire to immerse herself deeper within the Pilates Method she decided to participate in a comprehensive certification program at The Body in Balance Studio, as well as ongoing education workshops with BASI® and Bodymotion®.

Jenny Döll

studied music and physical education (Dalcroze Eurhythmics) at the Folkwang Hochschule Essen and the UdK Berlin. Her love for creative and conscious movement led her to Freiburg im Breisgau, where she completed a stage dance education at “bewegungs-art”. After several years of freelance work as a dancer and dance teacher, she looked for further ways to pass on her joy of movement. In 2016, she completed her BASI Pilates Mat Certification. She also participated in ongoing education workshops with Polestar and Bodymotion. Currently she is participating in the BASI comprehensive teaching program as well as participating in a seminar for somatic work with children.

Her classes are influenced by her rich movement experience in dance, as well as incorporating elements from various somatic techniques. She views the body as a field of experience of one’s own vitality. With it, in it, and through it, we understand the world and ourselves. Jenny’s goal is to make this liveliness come alive. With a variety of images as well as through sensitive and precise tactile assistance, she supports her participants in learning to feel the movement in their own body more accurately and thus efficiently train strength and flexibility.

In my classes, I make sure to train the whole body without losing focus on detail. I think Pilates is a very good way to improve the strength and flexibility of the body, while also finding mental calm.“


Romina Brocke

Romina was born and raised in Berlin and studied contemporary dance at the Dance Academy Balance 1 in 2001.

In her professional career as a dancer, she realized how important it is to take care of your body and yourself. Since then, Pilates training has always provided a perfect balance for her and helps her to stay healthy and injury-free.

In addition to her dance career, she worked as a model and dance teacher. In 2010 she did further training as a masseuse, in 2011 as a Nordic Walking Instructor and in 2014 she completed the Pilates Teacher Training at Body Balance Pilates. In order to meet the physical responsibility towards her clients, Romina decided in 2015 to pursue additional training in anatomy, with focus on learning modifications and variations for physical limitations within the Pilates Training.

Starting in 2015, she enjoyed a three-year education program to become a fitness and wellness coach, in order to immerse herself more in the matter of body, mind and spirit.

The internship in a Pilates studio in Berlin in 2018 inspired her to learn more about the work with the Pilates equipment. She was allowed to audit group and private sessions the on the Pilates equipment and was fascinated by how much the Pilates equipment is conducive to support the work with clients, focussing on prevention and rehabilitation.

So in 2019 Romina decided to complete the Comprehensive Teacher Training Course with BASI.

Romina considers her work as a Pilates Instructor as being precise and intuitive, putting the physical well-being of her clients first.

Chris Breuer


Rebecca Buhner

grew up in the United States and has lived in Berlin since 2015. She spent her childhood and teen years practicing Tae Kwon Do. After a long movement break and many years working a desk job, Rebecca rediscovered the joy of movement in many forms, among them Pilates, in her mid 20s. She was impressed at how Pilates combated the physical effects of a desk job while also making her feel stronger in her physical hobbies of dancing and running. While the physical benefits of Pilates are numerous, Rebecca was most impressed by the benefit to her mental health, finding an increasing sense of inner peace and self-confidence through her practice. She knows Pilates can strengthen both the mind and body and aims to help clients learn how to work together with their bodies and foster self-confidence through movement. She has been completing her BASI comprehensive teacher training in Berlin since 2022.
