Offer your clients the only anatomy content based on spirality: Anatomy Inspired.

Created by clinical anatomist, Dr Karen Kirkness, this asynchronous online course is especially compatible with 200 Hour Yoga Teacher Training Courses.  

Dr Kirkness presents the foundations of classical anatomy in conversation with contemporary principles of spirality, biotensegrity & fascia science.

Discover SPIRAL ANATOMY via VIRTUAL Dissection

You could call Dr. Karen Kirkness an anatomy nerd and she wouldn't flinch.

Why trust Dr. K with your professional training?

For starters, she literally wrote the book on spiral anatomy in yoga. With her MSc in Human Anatomy & Ph.D. in Medical Sciences concentrating on anatomy pedagogy, Dr. Kirkness is obsessed with facilitating your transformation as a movement educator without you having to go back to school in the process. 

Get to know her style in one of these short dissections as you prime yourself for a deep dive into spiral anatomy.


Start your journey from the Earth upwards. Karen demonstrates the grounding spiral of the foot using the Visible Body virtual cadaver.


How do we greet the sky? Learn about the scapulohumeral rhythm in this free 15-minute demonstration using the Visible Body virtual cadaver.


The pelvifemoral rhythm links the femur, pelvis, sacrum, and lumbar tissues into a complex function region. See how it links into the Axial Matrix here.

Professionalize your PASSION for intelligent movement.  

You don't have to be a clinical anatomist or work in a lab to understand the helical basis of human form and function.

If you are a movement educator, your work teaching people how to breathe and move optimally just got easier.

The Five Filaments spiral motion rubric is a simple, evidence-based approach to understanding biomechanics and talking about functional movement with your clients in practice.
