Course program

The RYT-300-Hour Yoga Mastery by Happy Jack Yoga University is a Yoga Alliance-accredited advanced yoga teacher training delivered fully online. Rather than a linear curriculum, the program is built as a self-directed path through 12 in-depth 25-hour courses, giving certified teachers the freedom to deepen their practice in the directions that matter most to them.

This training is designed for yoga teachers who have already completed a 200-hour Yoga Teacher Training and want to continue toward RYT-500 registration or deepen their practice and teaching. It also suits long-time yoga practitioners who want to explore advanced topics at their own pace.

Students will learn advanced yoga teaching and practice by selecting any 12 RYT-25-Hour courses from a library of 30+ offerings, organized around five themes:

– Growth: business of yoga, certified yoga life coaching, leadership and voice, vocal expression, sharing circle facilitation, social media skills for teachers
– Philosophy: Bhagavad Gita, Bhakti Yoga, Buddhist Psychology and Mindfulness, Divine Feminine and Yoga Goddesses, Krishna and Christ, Yoga Philosophy and Spirituality
– Healing: Kundalini Yoga, Pain Relief, Therapeutic Tools for Yoga Teachers, Trauma-Informed Yoga, Yoga for Grief, Yoga for Mental Health, Boost Your Immune System
– Inclusion: Prenatal Yoga, Yoga for Conflict, Yoga for Everyone, Yoga for Injuries
– Restore: Ayurveda, Meditation, Pranayama Mantra and Mudras, Restorative Yoga, Yin Yoga, Yoga for Spiritual Care, Yoga Nidra

Additionally, students can participate in live-delivered intensives such as Bhakti Yoga Conference, The Science of Yoga, Ayurveda Training, and Pranayama, Mantra and Mudras.

The program is led by the founders Jack Boken and Hanna von Hafenbrädl, both E-RYT 500 with Yoga Alliance. Jack holds a Master of Divinity from Harvard Divinity School, an MBA, and certifications as a Tony Robbins Trainer and High Performance Coach. Hanna is a yoga therapist and Grief Support Practitioner completing master’s-level training in Integrative Yoga Psychotherapy in London. Individual 25-hour courses are taught by the founders and a rotating faculty of guest mentors. The school, founded in 2010, has certified more than 800 teachers across 30+ countries.

The format is hybrid: most coursework is self-paced and pre-recorded, completed at the student’s own speed through the school’s membership platform. Optional weekly live Zoom calls with Jack, Hanna, and guest mentors add live learning and community connection, and the 2026 calendar includes scheduled live course intensives. Access is delivered through an ongoing membership that also unlocks the school’s full 30+ course library. The membership starts with a 30-day free trial and can be billed annually or monthly.

On completion, graduates are eligible to register as RYT-300 with Yoga Alliance. Combined with an existing RYT-200, the credential opens the path to full RYT-500 registration — the highest registered teacher designation with Yoga Alliance.

I'm so glad I took this training. It was affordable, and the curriculum was flexible. I worked at my own pace and took so much from the whole experience, deepening both my practice and my teaching. I feel like I've grown immensely as a person throughout this training, and I'm eager to continue my journey as a yoga teacher.
Gail Wilson

I would certainly recommend the 200YTT to anyone considering it. I got a holistic experience, not just a teacher training. This is a gift.

I just completed my YTT500hr certification with HJYU, which all started back in 2019 when my brother, cousin, and I all joined Happy Jack's YTT200hr Hero's Journey in Muskoka Ontario with open eyes and open hearts. It has been such a fulfilling journey for me, and by no means the end. HJYU's community is filled with incredible people!

I did my YTT 200 HOUR training through happy Jack and honestly best decision I took. Jack and Hanna are wonder people and they truly intent you not to just get a certificate but help you transform yourself the best version. The community is also great, everyone's really supportive and it is such a safe space to grow and be vulnerable.

I have had an amazing experience doing the 200 hr. teacher training course at Happy Jack. I have felt safe all the time and been challenged to do what I didn't expected I could. I can only recommend it if you want to do something great for yourself.
