Our Commitment

Woman learning yoga online

Sustainable Asana Yoga Foundation (SAYF) was born from decades of experience, practice, and purpose! This program was created to reduce the likelihood of asana injury, as there is an unmet need for greater understanding of human movement mechanics in the yoga community. Research is limited, tradition is diverse, and experience varies.

There are so many opinions and contradictions on how to approach yoga-asana that it can be confusing for even an experienced, educated, and well-intentioned teacher or practitioner. SAYF is both simple and comprehensive. There are some amazing trainers and teachers who are now offering movement mechanics education, and, for that, we are so grateful. SAYF can support even those programs, as an affordable and easily accessible option.
