about us



Sonja has had movement at the forefront of her life for as long as she can remember - growing up as a competitive figure skater in Austria, she later moved on to compete in show dance with her group Royal Jokers Dance Crew. Subsequently she's expanded her interests to include her current obsession with handstands which has brought her to travel the world in order to learn from several renowned teachers. She shared her journey, including many interviews with handbalancers all around the world, through her work at Handstand Diary. Acting as the Founder, CEO, and Head Coach at nook.


Sonja currently resides in the beautiful foothills of the Alps with her husband and now business partner, Ivo. She has found her purpose in showing up daily for her students to guide them to their full potential and in building a community of movers from all around the world through nook.

After deciding to specialize in bodyweight skill training he got his Calisthenics Coach certification in Argentina and finished an Exercise Science Program at the University of Colorado. Gian is a curious spirit at heart and keeps reading and studying every day to stay on top of the latest research on Exercise Science and Training.



Ivo is originally from Austria and has long been fascinated with not only the art, but the science of photography and film. Several years ago he began working as a photographer and videographer, shooting for Handstand Diary as he and Sonja traveled the world. It was during that time that he realized film was the amalgamation of his appreciation for not only capturing the moment, but also sharing it with others.


Similarly, Ivo loves optimizing processes and has a natural affinity towards all things tech and numbers. He is therefore perfectly suited to be the one behind the scenes (and behind the lens) at nook, making sure that the website and video platforms stay up-to-date. Ultimately, he strives to provide you with an excellent quality interface and digital experience so you can stay focused on what's truly important.
