Reproductive health responds to movement. That was our founding principle for The Fertility Class.
We built this program after healing our own hormonal challenges - severe PCOS (PMOS) and hypothalamic amenorrhea - through a specific system of targeted pelvic exercises.
The right movement sequences, done consistently and timed to the menstrual cycle, support ovulation, improve pelvic circulation, and regulate the hormonal environment that both cycle health and conception depend on. We know this because we have lived it, and have since taught tens of thousands of women worldwide.
The Fertility Class exists for women who are trying to conceive, working to regulate an irregular cycle, managing PCOS (PMOS), or learning to understand their own reproductive health. A global, on-demand program built on the Aviva Method movement practice that has been used by women since the 1960s.
The Fertility Class workouts are short, targeted movement sessions designed to support reproductive and hormonal health at each phase of the menstrual cycle. Rooted in the Aviva Method and modernized through 15 years of teaching and research, every movement has a clear physiological purpose.
The movement sequences are designed to stimulate blood flow to the reproductive organs, support lymphatic circulation in the pelvis, and regulate the hormonal axis that governs the menstrual cycle. Classes are organized by cycle phase - follicular, ovulatory, luteal, menstrual - and by goal: natural conception, IVF preparation, cycle regulation. Each class is 20 to 30 minutes.
The relationship between movement and reproductive health has been understood across cultures for centuries. Aviva Steiner was the trailblazer to formalize it.
A Hungarian-born dancer and physiotherapist, Steiner spent decades observing something medicine had largely missed: that specific pelvic movement sequences reliably influenced menstrual regularity and reproductive health. She taught this work across Eastern Europe and Israel, refining her method through direct practice with thousands of women.
We discovered her method through our own hormonal and fertility challenges. The results were so significant that we spent two years in the full instructor certification, and have been teaching and developing these protocols for 15 years since. We then built The Fertility Class to bring this work to women everywhere.
We continue to work alongside clinicians and research groups to continuously build on our program and further the formal evidence base.

ZSOFIA JAMIESON
Co-Founder | Certified Aviva Method Instructor
Zsofia spent twenty years as a fashion executive, including a decade at Net-a-Porter. Alongside that career, she built deep expertise in the Aviva Method. She found it after being diagnosed with severe PCOS, used it to regulate her cycle and conceive, completed the full 2 year instructor certification program, and taught it privately for over a decade.
MARTA HAN
Co-Founder | Certified Aviva Method Instructor | Health Coach | Yoga Teacher
Marta trained as a ballroom dancer, is a yoga teacher and health coach. She came across the Aviva Method while navigating hypothalamic amenorrhea, a condition that had stopped her cycle entirely, used it to restore her health, and completed the 2 year Aviva Method instructor certification. She has been teaching the method for 10 years, bringing her background in movement, coaching, and functional health to every class.
With a combined 25 years experience as Aviva Method teachers, we created The Fertility Class™ to offer women worldwide what we wish we had, a proven, on-demand movement practice for reproductive and hormonal health, taught by instructors who have lived it and who truly care about women's health.
“The Fertility Class is the culmination of our combined 25 years of experience, empowering women to take control of their fertility health through movement. After struggling for many years ourselves, we turned our journeys into a solution for others.”
