Level 1: Yin Yoga Asana & Biomechanics

October - November, 2022

This is a high-touch program with lots of personalized support, so class size is limited. Get on the waitlist to be notified first when registration opens (late spring for Fall 2022 cohort).

Referred to as "The Quiet Practice" by its innovator Paul Grilley, Yin Yoga offers a framework for attending to the often overlooked inner realms of our body, mind, and spirit. The simple, floor-based postures, held for several minutes, provide a unique opportunity to release deeply held tension, free stagnant or blocked energy, and cultivate a peaceful quality of mind.

In Level 1: Yin Yoga Asana & Biomechanics, you will learn the essential elements of practicing and teaching Yin Yoga.

* Insight Yoga Institute Credit is now available. See Below. *

Learning Objectives

This online course unfolds over three weekends. In addition to lectures and posture labs, each weekend will include multiple Yin Yoga classes for an embodied experience of the theories behind the practice.

You'll also get lots of access to the instructor, Jennifer O'Sullivan, through a virtual sangha, optional weekly Yin Yoga classes, and virtual office hours.

History and Principles of Yin Yoga - Discover the Taoist roots of Yin Yoga & its complementary relationship to other forms of yoga.

Posture Labs - Learn how to expertly practice and teach the essential Yin Yoga poses and the variations that support each individual's anatomical structure.

Safety & Personalization - Learn how to help your students safely explore their own body's capacities and use props to creatively enhance their experience in the poses.

Fundamentals of Functional Anatomy - Find out how skeletal variation, biomechanics, and the Theory of Exercise help us understand how to support individual students and design innovative class plans.

Fascia - Learn about fascia physiology and how Yin Yoga affects this ubiquitous tissue.

Sensation - Learn the basics of pain science and how to appropriately play the edge in Yin Yoga postures. You'll also develop an understanding of the difference between tension and compression and how to relate that to your students.

Principles of Teaching Yin Yoga - Learn and practice teaching masterful Yin Yoga classes including sequencing, cueing, and holding the space for your students’ personal experiences.


"In my 30 years as a practitioner, this was, by far, one of the best trainings I've attended. Jennifer is extremely knowledgeable on a wide variety of yoga and mindfulness practices. It was an honor to learn from her. I'd recommend this training to anyone with an interest in Yin, anatomy, philosophy, and mindfulness.

- Randi W.

"I would really recommend the Yin Yoga & Biomechanics training with Jen. She has a wealth of knowledge, years of experience, and the variety of her own teachers results in a most comprehensive and evidence-based curriculum. Teachers would be lucky to gain such a thorough grounding in the practice."

- Grace T.

"This training was a well-balanced program that included segments like posture lab, in which we were able to gain a better understanding of individual experiences that can not be found in textbooks. I appreciated the way Jen organized and held the space for the group so that the learning environment had elements of in-person training."

- Dolly L.

"Jen provides a wonderful container for growth throughout her entire Level 1: Yin Yoga Asana & Biomechanics course. Besides the "how-tos" of guiding a yin yoga practice for students, she includes why to practice and how to allow students to take and retain agency for themselves. I did not expect to be so drawn to the philosophies, but I left wanting to learn more! The instruction on anatomy included information I hadn't heard anywhere before, and I left with a deeper understanding of how different we are on the inside, as well as the outside. Jen's course is a terrific value, too."

- Karen C.

"I truly think this certification program was one of the best I have ever taken. The care and attention that Jen put into developing a comprehensive, informative, organized program was evident. Every activity was well thought out and built upon the knowledge we were gaining from our readings and lectures, to culminate in a great understanding of the foundation, principles, and practice of Yin. The program was the perfect blend of lecture, readings, hands-on demonstrations, group practice, and leading others in practice. As a hatha yoga teacher, I feel like Jen's training has made me a better yoga teacher beyond Yin. Thanks for all you do, Jen!"

- Jill S.

"Jen's knowledge and delivery is fantastic. Her ability to organize and structure information in digestible chunks was so helpful to my application of this material in my practice and teaching. She has helped me view my practice in such exciting new ways. Every minute was intentional and well-spent!"

- Katie A.

"Jen's teaching is passionate, direct and highly educational. Her loving kindness is only surpassed by her thorough knowledge of physical, energetic and mindfulness practices. This training is totally worth the time and money. I am walking away with a lot of useful information for both my personal practice and teaching practice."

- Layne C.

Frequently Asked Questions

When does this course start and and finish?
The schedule will be posted when registration opens.
How long do I have access to the course materials?
Some lectures will be recorded for your reference and will be available forever. In the future, if I close down this site, you'll have a chance to download the materials to keep.
For how long can I take the Monday Yin Yoga classes?
The classes are included with your tuition for the duration of this course.
What if I can't attend all the sessions?
If you miss live lectures, you can watch the recordings and write an extra quiz to show understanding of the material. If you miss posture labs, you'll need to make-up the material by partnering with another student who can go over the content with you or by booking time with the instructor at $150/hour.
How much time should I plan to spend in between sessions?
There are 11 non-contact hours built into the course which covers Fascia 101, readings, assignments, posture surveys, and final assignment, turned in after our last live session.
Do I have to be a yoga teacher to attend this training?
No, you don't need to be a teacher to attend this program and get a lot out of it. In my in-person trainings, I usually have several students who aren't teachers who do really well with all components of the course including the quizzes and final assignment. Non-students find the program to be very enriching for their personal exploration of yoga. However, you will not be qualified to teach Yin or any other type of yoga after this program. Foundational 200hr trainings cover a lot of material that will not be covered in this program. Should you decide to do a 200hr level 1 teacher training program in the future, you could certainly teach Yin Yoga afterwards.
Does this program qualify for Yoga Alliance CEUs?
Yes. Upon full and successful completion of the program including the final assignment to be turned in after the last live session, you'll receive a PDF certificate via email which you can submit to Yoga Alliance for proof of credit. Through the end of 2021, Yoga Alliance is allowing for virtual programs to count for their full amount. Should Yoga Alliance discontinue their virtual training exemption, this course would still qualify for 20 non-contact CEUs.
Can I apply this course towards my yoga training?
This course qualifies towards the Yin Anatomy requirement for Sarah Power's Insight Yoga Institute. Occasionally, other 300hr programs will count this course as an elective. You'll want to contact your yoga school about that.
Can I include this course as part of a yoga training that I offer?
If you are interested in including Yin Yoga as part of your 300hr training program, get in touch: https://www.sati.yoga/contact.html
Do I need special software to access the course?
We will use Zoom for all of our live sessions, weekly classes, and instructor office hours. Zoom is available on all major platforms and mobile devices.

What are my payment options?
You can pay in full right away using Visa, MasterCard, American Express, Pay Pal, and Apple Pay. All transactions are encrypted and secure. Payment plans are available along with a limited number of scholarships for people who share yoga with underserved communities. Get in touch if you are interested in either of these options: https://www.sati.yoga/contact.html
