Someone was telling me about a martial arts/kickboxing class at Gold's Gym that's held in the basement of a Catholic Church just a couple blocks from the GVSU DeVos Center. The person couldn't identify the church (I asked him St. Mary's? St. James? St. Adalbert's? Sacred Heart? but none of them sounded familiar).As far as I know, Gold's Gym doesn't have any locations in Grand Rapids. Does anyone know what and where this gym is?
