Laura Postor
Gym ownership isn't new to Laura. She built and owned three Seattle-area gyms, Big Iron Gym, where she created the Big Iron Babe community — empowering women to feel strong and capable in male-dominated spaces.
She's also a women's strength coach, perinatal corrective exercise specialist, nutrition coach, IFBB Pro athlete and a doula with more than a decade supporting women through pregnancy, postpartum and everything in between — and a mother of three.
“The work is not about bouncing back. It's about building something real.”
Materna is the next chapter: a studio built for women from the ground up, with the expertise, structure and care every woman deserves — at every stage of life.
