FAQs About 300 Hour Yoga Teacher Training

Meet Your Instructor, Yogi Aaron

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. 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.

Yogi Aaron’s sense of humor, contagious laugh, courageous and adventurous spirit, and his own healing journey of overcoming pain and discovering and living his true life’s purpose makes him a stand-out and favored leading yoga teacher today.

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.

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.

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.

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.
