What To Expect In A Yoga Teacher Training at Blue Osa

Yoga Teacher Training Review

Want to Know More?

Why study with Yogi Aaron? Who is my teacher?

Blue Osa is home to one of the most transformative, life-changing yoga teacher training in Costa Rica!

Each training has been carefully crafted by the world-renowned teacher, Yogi Aaron. During your experience, you will be guided on a journey of self-exploration, manifestation, and the cultivation of a purposeful life. Not only will you leave this training with a solid foundation for success as a yoga teacher, but you will also come to have a deeper relationship with yourself.

Who is Yogi Aaron?

Yogi Aaron is the owner, operator, and lead yoga facilitator at Blue Osa. During his 30 years of study, Yogi Aaron has developed an intrinsic understanding of yogic philosophy, anatomy, and the subtle body. He has studied under yogic masters such as Alan Finger, Bryan Kest, Genny Kapuler, Rod Stryker, Swami Rama, and David Swenson, among others.

Throughout his journey, Aaron has made several pilgrimages to the Himalayas, where he sought a deeper understanding of the Vedic tradition and Tantric pathways. These experiences blessed him with the opportunity to mentor under several spiritual masters and inspired him to create a yogic community in the lush Costa Rican jungle. And so, Blue Osa was born!

Creator of Applied Yoga Anatomy + Muscle Activation™ Yogi Aaron brings three decades worth of study, mentorship, and experience into his teachings, with a strong emphasis on yoga therapy and alignment.

“My passion is teaching yoga while guiding people to live a pain-free life to they may manifest and live their purpose. My desire is for each person to tap into their limitless potential and develop the confidence to embody yoga, both on and off the mat, so we’re able to reveal our best selves and shine brightly.”

I’m meditating every day and now my husband is too! Thank you Aaron. You’re changing the world and it needs you now. 
~ sandy F

I would recommend Yogi Aaron’s teacher trainings to anyone. Even if you don’t intend to teach, what you will learn from the trainings will open your eyes to new possibilities and understanding and to loving yourself more.
~ Mic

Aaron incorporated all aspects of yoga into this training, so if you’re looking for more out of your yoga journey, this is the place for you.
~ Katie M

Yogi Aaron at last is an incredible host and teacher. He leads with love and makes all people feel welcome in his sacred home. He is insightful and well-prepared to deliver an experience that is truly life-changing.
~ Chris R

Hello there my friend! I was thinking of you these past few weeks, during which I’ve been living in the Nepalese mountains.
I’m grateful for having been drawn to some wildly powerful places that helped me to internalize many lessons, and bring clarity to some of the challenges I was working through during my time spent at Blue Osa. I wanted to let you know I’ve felt a particular appreciation for your capacity as a space-holder and witness, and find it admirable how you remained seemingly un-phased by what could easily be triggering actions on the part of others (e.g. myself).

~ Varun

I appreciate and have so much love for you, the space you’ve created, and the knowledge you have shared. Life is all about relationships and the encounters you have with people, and the encounter and time spent with you, my classmates, staff, and locals have contributed to who I am today and will carry with me for the rest of my life. May our paths will cross again one day.
~ Cassie O

This experience surprised me in so many positive ways.

The two weeks for me were unbelievably introspective. It was like a two-week therapy session with myself. Only I had the guidance of Yogi Aaron and the support of a loving community.

The self-paced content has been awesome. Being able to rewind and pause the videos allows me to better understand the content and gives me time to reflect. I like seeing the length of time required to watch the videos in each section so that I can set goals and realistically plan my day. The worksheets and quizzes are just the right lengths, in my opinion, they are engaging without feeling like ‘homework.’ Being able to retake the quizzes is nice because I can go back to previous lessons and reinforce my understanding if I missed something. And I like listening to your anecdotes and examples for each topic (huge Sex and the City fan over here!!).

Even if someone doesn’t want a certification, having this time for introspection, to learn about your body, creating a fantastic community of people, and developing an excellent relationship with Yogi Aaron, would be an uplifting experience for anyone.
~ Kali

What style(s) of yoga will we be covering?

The Blue Osa YTT methodology has been influenced by the Himalayan Tradition of Yoga, which combines the wisdom of Patanjali’s Yoga Sutras and teachings passed down from a long history of yoga masters. We include a number of lineages such as Hatha, Iyengar, Vinyasa, and Kundalini.

Our holistic approach to teaching embodies the belief, “Function Over Form.”

Yoga is for everybody and we have created a teacher training that focuses on the individual. We provide you with the tools to confidently teach both private and group classes.

With the inclusion of Applied Yoga Anatomy and Muscle Activation™, you will have a signature experience that focuses on both muscle activation techniques and yoga therapy to benefit both you and your future students.

Does this program meet Yoga Alliance's international certification standards?

As a national accrediting organization for the yoga community, Yoga Alliance® provides a set of educational standards for yoga schools that specify hours or study in educational categories.

Blue Osa’s 200-hr RYT and 300-hr RYT with Yogi Aaron are accredited through Yoga Alliance®. Regardless of whether you join us for our 14 or 28-day YTT, you can register through this governing body upon receipt of your Blue Osa certification.

Yoga Alliance certification

What is the difference between the 200, 300 and 500 hour programs?

Blue Osa is a recognized yoga school by Yoga Alliance.

Yoga Alliance certification

Blue Osa provides a 200-hr foundational yoga teacher training that will equip you with the necessary learning to be a successful yoga teacher. This course will ensure you are confident in your alignment, cues, subtle anatomy and terminology. It’s a fantastic intro to teaching and will guarantee you success as you begin your teaching journey.

Blue Osa offers an advanced 300-hour teacher training that is available to students who have previously completed a 200-hr YTT (either through Blue Osa or another accredited school.) This course offers students the opportunity to deepen their foundational knowledge, enhance their teaching abilities and further develop their leadership skills as both a teacher and practitioner.

A 500-hr YTT would include both a 200 and 300-hr YTT or a 500-hr YTT respectively. Though many schools do not offer the latter and students cannot commit to the total time required, most teachers complete their 200 and 300 hours separately.

For more information on the differences, please read this article.


I have already completed my 200 hour / 300 hour / 500 hour. Why should I consider one of your immersions?

Immersions begin on Saturday at 3:00 p.m. and commence on the final Friday evening. This will allow for the option of a Saturday morning departure.

We recommend arriving in Costa Rica one or two days prior to starting the immersion and would suggest arriving in Puerto Jimenez on Friday evening so as to settle into the space and enjoy your first sunrise on the beach.

Please note that should you miss hours for any reason, you will be required to make up the time prior to receiving your certification.

How many times a year do you offer this? How many people attend?

Space is limited!

We believe in keeping our class size small. This means more individual, hands-on learning and teaching for you!

The maximum number of students we accept for our immersions is 25. We also limit the amount of training held per year so if you’re ready to join us on the beach in Costa Rica, sign up NOW!

Why is this immersion so affordable?

Blue Osa was created with the intention of bringing yoga to as many people as possible and Yogi Aaron believes in welcoming anyone who is ready to experience total transformation to come join him in his little slice of paradise.

The power of a yoga-immersion cannot be overstated.

When it’s combined with a supportive community, ocean waves, tropical birds, healthy food and room to breathe, there can be no greater impact to a person’s life. And when we are all living our best life, fully aligned with our path, we stand to make a greater difference in the world.

It has been this philosophy that has inspired Aaron to offer such affordable pricing and it continues to drive him in sharing his wisdom with his students.

I am on a really strict budget. What other costs are associated with these programs? What is NOT included?

We have catered our programs to be all-inclusive. This means that all lodging, farm-to-table meals, teacher-training and course material will be included as well as your certificate, upon completion.

Once we understand a little more about you, Yogi Aaron can help guide you into the perfect training for you.

Will this program cover the "business" aspects of becoming a yoga teacher?

As a former NYC yoga studio owner and as current co-owner of Blue Osa Yoga Retreat & Spa, Aaron has a wealth of knowledge available in this area, and will kindly field questions.

We will also give you access to our Business and Marketing Course For Yoga Teachers. This course will spend some time discussing the logistics of developing your own business as a yoga teacher.

Subjects to be discussed include how to find your first customers, how much to charge, where to teach, and best practices for growing your business.

I have an injury and/or need to adjust my practice. Will I hold the class back?

NO, you will NOT hold the class back. We will ALWAYS encourage you to only do what you are comfortable doing and to practice within the limitations of your own body.

Yoga is a personal practice. The first “value” we practice in yoga is non-harming.

Yogi Aaron’s background is in yoga therapy and the creator of Applied Anatomy. Therefore he teaches all of his classes to be therapeutic and healing. He is also very skillful at helping those with less mobile bodies to adjust their practice.

I don't have a strong yoga practice. Can I still participate in this program?

Absolutely! Even if you are relatively new to yoga, our yoga teacher training immersions are an excellent way to learn the art of yoga and cultivate a strong foundation for your life-long practice.

One of the strengths of our approach to yoga is how adaptable it is to the student. No matter where you are, there is a practice for you.

And frankly, some of the best teachers are the ones who can’t contort their bodies into pretzel shapes. Their limitations end up being an asset to their students.

I don't want to teach yoga. Why should I consider this Yoga Teacher Training Immersion?

Whether your goal is to teach yoga, deepen your personal practice, seek answers to some of life’s biggest questions, or simply find ways to live a more meaningful life, these Yoga Teacher Trainings are for YOU!

Yogi Aaron approaches every immersion with an open-heart and a desire to provide students with a safe space to explore their own personal depth.

This training is an opportunity for you to uncover truths about who you are and how yoga can help you live a more authentic life.

Surrender your worries to the soft sounds of the ocean waves. Nourish your body with farm-to-table cuisine. Get curious about yourself and your place in the world, and allow yourself to experience the peace and tranquility of Blue Osa.
