200-Hour O2 Yoga Teacher Training Online Program 2020-2021

Taking it to the Next Level

We do yoga for many different reasons. For those of us that it turns into a passion, we know all that care, dedication, focus, humility, and sense of humor that makes us return to our mats day after day, week after week, year after year. O2 Yoga owner and founder Mimi Loureiro says, “I like to teach people yoga because it makes them nicer.”  Time spent on your mat can be centering. Moving this way on the inhale and that way on the exhale is the key to a successful practice — that is all. Giving yourself the gift of 60, 75, or 90 minutes to focus on yoga and nothing else is what calms your nervous system and, indeed, makes you nicer.

What a 200-Hour Teacher Training can offer is the chance to learn more about the other side of practice: the teaching! Being a student is extremely different from being an instructor and getting the chance to learn the nuance of how to sequence a leveled class (Basics, Intermediate, and Power) with care and attention and then how to get up and lead students through that sequence while also watching and cuing for better alignment, stability and focus will transform your own experience on the mat forever. Whether your goal is to be a yoga teacher or simply delve more deeply into the how’s and the why’s, our Teacher Training program is for anyone interested in learning about the full 360-degree view of a yoga practice.

After 15 years of in-person trainings we have decided to offer our very first online-only course. Watch a short video of Mimi and Elliott inviting you to join us for teacher training. Here are some of the benefits of taking the course online:

  1. More flexibility with scheduling
  2. No travel required!
  3. If you have left the Boston area and miss O2, you can join us for this intimate experience!
  4. More affordable. We are offering this training for 1/2 of what the in-person tuition is.
  5. Now that so much more is offered remotely, you will get the extra benefit of learning to teach your classes both in-person and online.

Our training begins with a strong focus on the Primary Series of Astanga, both because it is the foundational influence of O2 Yoga-style classes and because it offers a consistent and predictable sequence for new teachers to learn the language of yoga. After that, we move on to the more creative aspects of planning an O2-style class with the goal of the training that all graduates of the program have a strong understanding of yoga-anatomy, sequencing, cuing and communication, yogic philosophy, energetics, and teaching online. To put it simply:  by the end of the training, you will have the knowledge and the confidence to stand up and teach a yoga class and then another, and another!

Join Mimi, Elliott, and other senior O2 instructors to explore, expand, and completely change your life. This is a Yoga Alliance 200-Hour Registered Teacher Training program.

Already 200-Hour certified? We open up the first two Astanga-based weekends to certified teachers as well as the elective courses.

We also offer the “elective” courses that are open to already certified teachers

*Students with a deep interest in Astanga Primary Series, Second Series, and Advanced Postures may also be eligible to attend these weekends. 

We limit the number of students in each training to ensure personal attention, so don’t wait to claim your spot in our yoga-nerdy program!

Teacher Training Frequently Asked Questions:

Will everyone know more than me?

Honestly, some people will but not all — and there are probably things that you know that no one else does!  Everyone brings his or her own experience, skill set, and background to the training and the result is usually a room full of people who are able to simultaneously teach and learn from each other.

Do I need to be able to do all the poses?

Not at all.  The hope is you will leave the training feeling confident about cueing students into a wide variety of postures, including ones you may not be able to do yourself.

Do I need to want to be a yoga teacher in order to take the training?

Absolutely not!  People choose to do teacher training for lots of different reasons — maybe just to deepen their practice or to learn about the other side of practice or to spend time with like-minded people who also love yoga.

What are my options for payment?

We accept cash, credit, or check or you can opt to do financing through PayPal.  A down payment of $500 is needed to secure your spot.  Payment plans can then be worked out on an individual basis (email mimi@o2yoga.com for more info).

What if I need to miss a weekend

With an online format, we will be recording all lecture content which will be available to all after the fact. We do not recommend missing any of it as you will lose the ability to learn in real time and participate in the discussion but will have the option to fill in some gaps as we move along.


Will O2 Yoga Teacher Training change my life?

It sounds cliche to say “yes,” but the answer is “yes.”  Want to know how or why?  Ask any of our teachers before or after class — all of them have gone through our program and they each have a story to share about their experiences.

I am a busy professional — will this training be too much to take on?

It is a time commitment but our recent TT grads have all managed to work things out with their employers in order to get this training to fit in with what may already be a hectic life.

How is the training structured?

We begin with our foundational practice:  Primary Series.  You learn to cue this set series of postures before moving on to the more “O2 style” creative sequencing.  There is some seated lecture, but most of the day is interactive, either in practice, cueing a practice, or working with a partner or in groups on on teaching, sequencing, and pacing.  Expect at least 60-90 minutes of  practice of some variety every time you meet, as well as lots of opportunities to get up, move around, and apply information.

What do I get at the end of the training?

You get a certificate saying you completed your 200-Hour Teacher Training.  With this document in hand, you can then choose to register as a yoga teacher with Yoga Alliance.

What’s good “prep” for the training?
Be as familiar with the O2-style of yoga as you can (i.e. practice with us a lot!) — and definitely take as many Astanga classes as you can!

Can I fail the training?

**Other questions, don’t hesitate to ask one of our teachers at the studio or email mimi@o2yoga.com**

TT Class of 2016


“When you sign up for Teacher Training you know this course will change your life – that’s kind of the point, right? –  but the way it does so will surprise you. It will deeply challenge you and have you thinking in so many more constructive and creative ways than you thought possible. And the best part? At the end of the class, you are officially certified to share your passion and what you’ve learned with others.”
~ Kat DeStefano

“Mimi’s classes at O2 always draw on creative energy and exploration while prioritizing student safety, expert cuing. If you take class with Mimi, it becomes evident that she’s the inspiring teacher you want to learn from.  Mimi’s gift is her teaching and she empowers and enables her Teacher Trainees with her passion for smart yoga.  I completed training with a strong understanding of the Astanga system and therefore the ability to sequence and plan intelligent classes, modify for beginners or injured students, and moreover, teach new and advanced students alike.  Mimi’s training was the beginning and only fueled a passion to expand my yoga teaching practice further.”
~ Devon Wilson-Hill

“O2 Teacher Training brought me closer to the O2 community, introduced me to a great group of friends, and changed my yoga practice in some pretty radical ways. I was never a big Astanga practitioner before TT, but learning more about the Astanga tradition, the postures, and the rationale behind the sequence really gave me an appreciation for how organized and balanced a practice it is. The program unlocked some ‘mysteries’ about sequencing and structuring a class. The alignment and anatomy discussions made me a more humble and patient patient practitioner because I now back out of postures that I used to ‘muscle’ myself into and use more props to better my alignment. I feel very lucky to have been trained by O2. There are so many teacher training programs out there, but I believe that O2’s is unique in the quality and depth of content and the community that surrounds it. Because the group’s size is limited, you will have many opportunities to cue sequences and give adjustments, and you’re given a ton of personal, thoughtful, constructive feedback. You’ll get to know the trainers and fellow trainees very well and it will be a supportive, welcoming group. Teacher Training will challenge your mind, your body, and will take you out of your comfort zone. Being able to stand up in front of a class and teach is so terrifying for many, and to be able to overcome that fear is a huge achievement!”
~ Kristen McCarron

“For me teacher training felt like a retreat, every weekend. I remember feel so energized and happy on Monday mornings after the weekend training sessions. Personally I felt that I spent all those hours being more conscious about my breath, my posture, my behavior, my connection with the teachers and my new TT friends. It raised my awareness and sense of self. It made me happy by allowing me to connect with other wonderful women and men. It felt like nourishment for the soul. I didn’t know this going in. I singed up because I love yoga and I got to experience an expansion of that love.”
~ Bora Vukaj

“Teacher Training was a life changing experience. It’s such an intense time of learning and challenging yourself. I remember on the first day of YTT, Mimi talking about the benefits of doing things you are comfortable with, that you don’t do well yet – and I could not agree more. I found it was so beneficial to my life to spend every weekend practicing something that I wasn’t good at and that I had to work really hard at. Especially because we were in such a supportive environment. I remember when fumbling through my first time teaching the whole room, Mimi said that despite nerves or forgetting a cue here and there, ‘If you can get people to breath you will change everything.’ I love that idea & I hope that every time someone comes to their mat in my class and breaths for 60, 75, everything changes for them.”

~ Ali Reeder

“Students come to yoga for various reasons. Some are looking for a physical workout, others are seeking relaxation to reduce stress, to find balance, or to heal from an injury. Whatever the reasons, most of us begin with asana, the physical work, and we keep practicing because it feels good. Yet over time, a shift occurs, as asana allows us to feel that there is something animating our physical form, deepens the ability to watch our minds, and attain a subtle shift in consciousness. The same is true of a teacher training program, as some students sign up with the primary intention of becoming a teacher, and others with the goal of deepening their personal practice.As a students of yoga, we have two sources of guidance, with the outer teacher being the one who guides students through asanas and transitions in safe, clear, and efficient ways. Those who have practiced with us at O2 for a period of time know that we believe anatomical knowledge informs class sequencing and our teacher training program is very focused in this regard. We feels it’s important for our teachers to understand how the muscles and joints work, the possible risks of injury, ways in which asana can be modified, how to use the breath and bandhas to direct the flow of prana, anatomical knowledge to inform proper alignment, the principals of intelligent sequencing, infusing our classes with creativity and playfulness, and guiding our students to deepen their relationship with their own practice. Without a doubt, our training program will deepen a student’s physical practice, but delving into the “why” and the “how”, as well as learning about the subtle body, enhances our inner teacher. This is the voice that informs our physical capabilities, tells us when we’ve reached our edge, when we have space to move beyond it, points out our emotional states, and the knowledge to find what feels right. This the starting point for cultivating a subtle energetic awakening to take the lessons from the mat out into the world.For me, Svadhyaya, or self-study, one of the Niyamas, or observances found within the eight limb path of the Yoga Sutras, is really the heart of yoga. To really do asana practice involves cultivating a consistent openness to being fully tuned in, so that the physical practice becomes a tool for self-exploration. Regardless of the reasons students come to our teacher training program, the result will be transformational. Where else can you invest 200 hours into your own personal yoga practice? There is something incredibly powerful in surrounding oneself with like minded individuals completely immersed into the world of yoga, and I often hear from our graduates, whether they end up teaching or not, that the program was life changing. The training community offers a unique opportunity to learn more about oneself, within a nurturing, supportive sanctuary that encourages growth, self-expression, and creativity. When I embarked upon our training program many years ago, I did so without the desire to teach and only wanted to learn more about something I loved. But along the way, a clarity of mind developed in which old patterns, or Samskaras, were brought to light, with the ability to let go of these patterns that were no longer serving me, thereby deepening a sense of self-awareness and connection to others. I learned to sit with discomfort and face those discomforts without fear, such as speaking in front of a roomful of people, or teaching a pose that my body had not mastered, and discovered life altering realizations that remain with me to this day. I feel it’s an incredible privilege to teach that which I feel most passionate about, and every year, am thrilled to share this knowledge with our trainees. But I’ll warn you: yogic insight can be addictive!”
