Port Huron Times Herald In some ways, opening The Wise Core fitness studio in St. Clair felt like a different kind of birth, owner Gigi Verstegen said. Although the “labor” was a lot longer, just over two months, it was also very emotional. There were tears, happiness and a lot of work went into bringing the studio to life that specializes in pregnant and postpartum women’s health and wellness. “It’s a dream come true,” Verstegen said. What is The Wise Core? Next to St. Clair Ace in the Riverview Plaza, The Wise Core is open 6 a.m. to 8 p.m. Monday through Friday by appointment and there is a Saturday class at 8 a.m. There is a play area for children so even if mom’s can’t get a babysitter they can still come in, Verstegen said.
