Level 1: Yin Yoga Asana & Biomechanics (35hrs)

Part of the Foundations of Yin Yoga & Mindfulness Teacher Training

(Registration closes on Sunday, January 3. Enrollment is limited to ensure a more personalized experience.)

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.

Learning Objectives

This 35-hour online course unfolds over two weekends. In addition to lectures and posture labs, each weekend will include one Yin Yoga class 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 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.

Frequently Asked Questions

When does this course start and and finish?
The live portions of this course begin on January 15th and end on January 31, 2020. You may turn in your final assignment until February 28, 2021.
How long do I have access to the course materials?
Recorded lectures and classes 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 starting January 18th through February 8th, 2021.
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 booking time with the instructor at $75/hour.
How much time should I plan to spend in between sessions?
There are 7 non-contact hours built into the course which covers readings, quizzes, 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 2020, 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 is not directly affiliated with a 200hr or 300hr yoga teacher training program. If you are interested in getting credit towards another course, you'll need to talk to the administrator of your school.
