What To Expect At Yoga Teacher Training

“Through Yogi Aaron, yoga teacher training has helped me not only become a good teacher, but helped me grow into my most authentic self!

Want to Know More?

Why is this training 28 days and not shorter and cheaper while there are so many others to chose from?

Today, you can find so many shorter and cheaper yoga teacher training immersions. One of our renowned competitors in Costa Rica is offering a 14-day immersion that is a little less than what we currently charge for 28-days.

After running this immersion for 6 years, we asked our past students if they would have appreciated a shorter immersion, and this is what they said.

I think the pace was great. Getting those 200 hours in fewer days would eliminate the rest days, and those were super necessary to avoid burnout. Besides, who would want to be at blue osa for LESS time! I’m just about ready to run away back there forever! Lol


The month was a long time but it gave us s chance to bond with each other in a way that a shorter time might not have. One reason I took it was because it was condensed but I have the leisure to be away that long. Not sure how you would get 200 hours in a shorter time. Would cut into our benefitting from your knowledge. Long answer for s no.


I chose Blue Osa because it was one of the longest immersions I could find-that’s what I was looking for. I think there was a good balance of free time in the afternoons/off days and work time. I also agree that we bonded so much in the last days of the training, that might not have happened if it were only 3 weeks long.


I feel like if it had been any shorter length of time I wouldn’t have gotten as much out of it. The immersion is so intense, it took me at least a week to acclimate to the schedule and get into retreat mode. It was nice to have a whole month to get used to the daily practice, study, and yet still find time to relax and unwind.


One month is the right amount of time! It allowed us to truly experience and see the benefits of daily practice. Anything shorter would have felt like we left unfinished. I should also say that going into it I had wished it was shorter because I had exactly one month off from work. BUT…I made it happen because I truly wanted to, and I’m so glad I did! People can make it work…we all did!


Wait!!! But I want to do a 14-day training at Blue Osa. Do you offer one?

Blue Osa is now offering a 14-day Yoga Teacher Training Immersion.

While we think that the best option is for people to invest 28 days of their life into an immersion that will truly transform them at every level, we have had too many requests to offer this in the past.

If you do decide to do a 14-day immersion, with us or elsewhere, remember that the experience will NOT be the same as giving a month to this practice.


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?

With wisdom and experience comes mastery!

With over 30 years of teaching experience, spiritual mentorship, yogic interns, and personal practice, Yogi Aaron comes fully prepared to offer you a teacher training like nothing you’ve experienced before.

I have already taken the Blue Osa Teacher Training. Should I / Can I take it again?

Absolutely! Be prepared to pick up new skills, nuances, and information the second time around! We welcome former grads to join us on the mat at a discounted rate. Contact Aaron for more details.

When are the book reports and assignments due?

In order to be presented with your 200 or 300-hr YTT certificate, you must complete the required reading and reports. These reports will be due three months following the completion of your immersion.

For example, if you completed your immersion on November 16th, your book reports would be due the following February 16th.

Don’t worry! You’ll have plenty of time to work on your reports throughout the immersion or you have the option of completing the required texts prior to beginning the course. It’s totally up to you!

Once you’ve successfully registered, we’ll send you out the required reading material and you can decide for yourself when you’d like to get working.

How many times a year do you offer the One-Month Immersion?

Space is limited!

We believe in keeping our class size small. This means more individual, hands-on learning and teaching for you! AND these exclusive programs are only offered once a year!!

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!

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.

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.

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.
