What is BIRTHFIT? 

(We're glad you asked.)

BIRTHFIT is a worldwide movement of women and men, coaches and athletes, practitioners, chiropractors, teachers, movers and shakers who are changing the game in the world of pregnancy, birth, and postpartum.

  • BIRTHFIT is a movement. It’s about pregnant and postpartum moms taking charge of their bodies and their decisions, and supporting one another’s journeys—together and apart.

  • BIRTHFIT is an approach to birth. We challenge the status quo and ask the questions no one else asks. We read, research, experiment & consolidate all the common sense, time-honored wisdom & recent studies we can find and present that information to you through various education models. Our pillars are fitness, nutrition, chiropractic & mindset. We unconditionally support YOU—the birth mom & birth partner—to make the best decision for you and Baby.

  • BIRTHFIT is a state of readiness. Childbirth is perhaps the most physical, mental & spiritual experience of a woman’s life. We want you to be ready in body, mind & spirit for the experience of birth and the lifelong journey that follows.

  • BIRTHFIT is your support team. We are a team of practitioners, educators, chiropractors, coaches, nutritionists, fellow mamas, men & women who are involved in our local communities and we are all rooting for YOU.

The Four Pillars of BIRTHFIT


To functionally train throughout the Motherhood Transition in all planes of motion to develop competencies and physical skills as well as enhance the main metabolic pathways.


To cultivate a relationship with food that is rich in color and nutrients from a wide variety of animals, fish, plants, fruits, fats, and starchy tubers, while nourishing the body through the different rhythms of life and the female cycle.


To create space between a stimulus and a response, to embrace a growth perspective, and create action around values in order to make decisions from a place of love rather than fear.


To open pathways from the cellular to the metaphysical level wherein a human can experience and express optimal health in body, mind, and soul.


Meet the BIRTHFIT GR Regional Director 


Dr. Theresa Osmer

Hi! I'm Theresa, owner of FLOW Chiropractic and the Regional Director of BIRTHFIT Grand Rapids!

I am the oldest of 5 girls, and am 100% convinced that the amazing women in my family are the inspiration for my passion when it comes to all things birth and babies.

I began following the BIRTHFIT blog in 2012 while trying to help navigate an amazing woman through her motherhood transition. More on that here. After that experience, I became a birth-junkie, and began to hyper-focus my continued professional development by obtaining my Webster Certification through the ICPA and Prenatal Yoga Certification through Blooma's Teacher Training, attending various prenatal, postpartum, and pelvic floor conferences/seminars, and finally applying and being accepted as a BIRTHFIT Regional Director for the 2018 class.

I strive to help women (and men) of childbearing years reach a state of optimal health and well-being through applying the Four Pillars of BIRTHFIT. I am passionate and have a hunger for knowledge, collaboration, and community. I want to make a difference in this world, and am starting in my local community of West Michigan.
