"As a former Ashtanga practitioner I had to unlearn a lot and relearn a new pain free way of yoga during my teacher training with Aaron. The way he integrates his knowledge of Applied Yoga Anatomy and Muscle Activation™ is a mindful and safe way to practice yoga. In a short period of time my shoulder pain got less and less and I felt more strength throughout my body.

Now I look at some poses in yoga in a different light and have a much greater understanding of their impact on the body."

~Hendrike - YTT Graduate, 2021



"I'm grateful for having clarity and overwhelming sense of peace I am taking away from 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 unphased by what could quickly be triggering actions from myself and others."

~Varun - YTT Graduate, 2017



"My time at Blue Osa was among the most incredible journeys I have ever undertaken, from both an amazing travel experience to probably the most substantial period of personal growth I have ever undertaken. From the friends and community I gained, to the awe inspiring yoga practices.

I am still in awe of everything I experienced in those two weeks. The wisdom you imparted upon us was simply life changing. I have never been exposed to yoga as profound as this experience. You are an incredible person and I thank you for opening the door to a whole new world to me."

~Stuart - YTT Graduate, 2023



"Being at Blue Osa woke me up.  I am finally consistently meditating for the first time in my life and I feel subtle yet powerful shifts in my outlook.

I am finally consistently meditating for the first time in my life and I feel subtle yet powerful shifts in my outlook. I see a difference in the way I react to things. I finally have some autonomy over my emotions.I see a difference in the way I react to things.

You had such a big impact on me and I've felt compelled to write you this to you."

~Christine - YTT Graduate, 2023



"This YTT at Blue Osa blew my mind, and really open my eyes to the possibilities of yoga.

Aaron is like a bright guiding light, he has such depth of knowledge and experience of these practices and traditions. I feel like I'm able to make so much more progress under his guidance.  A big win for me is my learning to speak with such COMPASSION, KNOWLEDGE, and CONFIDENCE.

I highly recommend this yoga teacher training at Blue Osa with Yogi Aaron to anyone interested in doing one! Regardless of whether you want to teach yoga or not, it'll be greatly beneficial to your life!"

~Hong - YTT Graduate, 2022



"I am so grateful for Yogi Aaron! I am now living a pain-free life. My yoga teacher training experience was magical and transformational. The training exceeded my expectations. This training guides us in the authentic yoga based in the Himalayan Tradition, and about stability of the body and mind through innovations like AYAMA (Applied Yoga Anatomy and Muscle Activation created by Yogi Aaron)!

I enjoyed learning how I can assist students with improving their range of motion through simple, yet incredibly effective exercises because we got the opportunity to put it to the test by experiencing these exercises ourselves and witness our own range of motion improve."

~Alexis - YTT Graduate, 2022

Your Teacher

Hi! I'm Yogi Aaron!


I look forward to welcoming you to my beachfront yoga retreat, Blue Osa, for a spiritually awakening experience.


I built Blue Osa to host groups in a safe, wild, and nurturing environment. I wanted to create a space where people could come and be immersed in a yogic lifestyle without all of the modern-day distractions. I wanted Blue Osa to help people come back home to themselves.


And since opening our doors, Blue Osa has provided just that to thousands of people.


Personally, I have 30+ years of yoga experience, have led countless yoga teacher training programs, and continue to embrace being a beginner at heart - constantly learning and expanding my own self-awareness and yogic knowledge.


I've designed Blue Osa's Yoga Teacher Training to be a perfect blend of the ancient and spiritual practices of yoga (influenced by the Himalayan tradition) offered alongside modern-day, science-backed methods like AYAMA™ (Applied Yoga Anatomy + Muscle Activation) which is a revolutionary approach to yoga that eliminates pain by optimizing muscle function.


I can't wait to have you join our Blue Osa family in a future training!


Our Farm-To-Table Food

At Blue Osa we believe that nutritious, wholesome food is not only the foundation for a productive life but is also essential for a happy one. Food that nourishes our soul not only needs to be healthy, but it also needs to be delicious too!

We are devoted to serving the freshest ingredients possible that are delivered daily to our kitchen. Whether it's pineapple from the Blue Osa property or squash from the farmers down the road, all produce supports the local economy.

This is truly a "farm-to-table" family-style dining experience. While attending our immersion, you'll enjoy three meals/day and be able to purchase smoothies and elixirs from our Juice Bar as desired. Tea, coffee, filtered water, and fruit are always available too. Dietary restriction? No problem, just let our friendly kitchen staff know in advance!

Your Blue Osa Family + Environment

Forget "staff," at Blue Osa we have family. From managers and chefs to spa therapists and tour guides, everyone plays a role in creating our immersive experience. Even our furry friends (think playful pups and curious cats) and the wild creatures roaming the grounds (exotic birds, little lizards, and the occasional crab) add to the unique atmosphere. And when you join our yoga immersion, you too become part of this extended family.

A truly special place that is run by special people.
January 16, 2024
I did a 200-hour yoga teacher training here in October 2023. The location is about an hour from the closest little town of Puerto Jimenez and is right on the beach on the lush Osa peninsula. It's a beautiful eco friendly property. There is a small spa, a beautiful meditation temple with Ghanesh inside, a lap pool if you don't feel like ocean swimming and a main pavilion. The yoga training I received was excellent - yoga philosophy core teachings, meditation practices and many muscle activation demonstrations and anatomy talks. I specifically chose this yoga teacher training because I wanted a way to safely do yoga poses without causing me further joint pain. I had found that yoga class always made my body tighten up a few days after going. This curriculum taught me everything I was hoping to learn on how to safely do yoga again and I got a ton of information on what yoga actually is. Thank you Aaron and Blue Osa team.

We were looking for a place to unplug and reset and the Blue Osa surpassed every expectation. It went beyond being surrounded by nature and the incredible animal kingdom, we were living among them. The grounds are beautifully cared for and the architecture blends in naturally with the setting and adds nicely to the Spiritual energy of the place. Having the ocean just steps away, or the pool, was a nice way to cool off and bask in relaxation. And speaking of relaxation, the spa package was just amazing and nurturing for the mind, body and spirit in such a beautiful setting. Thank you ladies. Loved your music too. Henry and the Blue Osa staff felt like family by the end of the week. They seemed to be one step ahead of what was needed at any given time and the meals prepared by the cooks were so consciously done, including the giving of thanks before dinner. We went to unplug and reset, what we experienced changed us forever. We will see you again Blue Osa, as you feel a part of the family now. With love and appreciation for a truly magical place and people! Sheila

My experience at Blue Osa was wonderful! Being dropped into the middle of the jungle and completely disconnected from Wi-Fi and electronics was extremely healing. From morning silence to yoga class in the evening every moment was enjoy able. All the meals were delicious and the evening presentation by the chef of dinner was something to look forward to. I also would recommend getting the juice package. You’ll get addicted to them and want them daily. Everything they make in the kitchen is amazing! If you’re looking to pamper yourself, I highly recommend getting a treatment at the spa. The estheticians are wonderful and I personally recommend the coffee scrub! More over the whole staff is fantastic! Not only are they preparing all your meals, booking all the spa appointments, and any excursions that you’d like to do but they also became my friends that I enjoyed talking with over my stay. Alex, Carlos, Henry, and Britchell are the heart and soul of Blue Osa they make you feel like family.

I normally don’t take the time to write reviews after a trip, but Blue Osa kept a little piece of my heart, so I felt compelled to share my experience. My wife and I stayed at Blue Osa in October (2023), and it was an amazing experience. From the moment we started our journey the staff at Blue Osa was fantastic. They answered our questions timely and made us feel very comfortable. They helped set up our in-country travel which went very smoothly. Upon arrival, the staff was accommodating, professional, and happy. I cannot say enough about the staff and management. We stayed in the Freedom room which was amazing. At first, we were worried that the lack of air conditioning would be a problem, but it wasn’t at all. The daily temperatures were great, and the evening and nightly breezes cooled the room down. Listening to the rain at night was peaceful and calming. My wife and I enjoyed the pool and spa. The spa staff and energy workers were great. This is saying something considering my wife and I have been to many spas. The spa is not big and, in many ways, it’s simple but that is what makes Blue Osa special, the simplicity. The yoga was fantastic. We enjoyed yoga each day at 4PM. We had three different yoga teachers while we were there and each one was great. The view from the Yoga Shala was stunning. Each morning I appreciated the morning silence. The Internet wasn’t available until 7:30AM and no one would converse during this time. It was nice to disconnect from modern society. Each morning I would sip coffee and watch the waves. I was greeted by beautiful birds and/or monkeys. The food was an experience. At most resorts, there are many food options to choose from and the portion sizes are massive. I normally order the “usual” (meat and starch) and never get out of my comfort zone. My wife and I enjoyed not knowing what Blue Osa was going to serve each day and I appreciated the fact that we were eating healthy food (lots of fresh fruit, vegetables, and vegan style meals). Every meal was unique and fantastic. I ate very differently than I normally do, and I stepped outside of my comfort zone. The portion sizes were smaller but there was always plenty of food if one wanted more. There were several other groups staying at the resort when we were there. The Blue Osa staff would set up the meals family style and we would all eat together. We would share stories and laugh while we ate amazing food. My wife and I had traveled to Costa Rica once before and stayed at a Four-Season Hotel which was beautiful, but it lacked the wonder of Blue Osa. If you are willing to step outside your comfort zone and immerse yourself into the Blue Osa way of life, you will be positively impacted by the experience. Blue Osa is truly magical. We will be back! Thank you from Matt and Lisa (USA - North Dakota)

What an incredible week I had at Blue Osa! The location is breathtaking, the food is so healthy and delicious, the vibe is relaxed and supportive, and the staff is so friendly and accommodating. I wish I could have spent more time there. The spa treatments were sublime, and the outings were well organized and fun. Whether you want to have an active vacation and see and do a lot, or keep it relaxed in one place, Blue Osa is an amazing destination in beautiful Costa Rica!
