The Y of Central Maryland plans to open a new facility by June in the North Plaza Shopping Center in Parkville. The location will be a full-service family-center Y that offers classes such as youth sports, swimming, water aerobics, martial arts, yoga, indoor cycling and exercise programs. The facility also will feature a fitness floor for cardio exercise and weight training, free child supervision, a teen/senior room, children's play area and family activities. The nonprofit has begun selling memberships for the new location at an office in North Plaza. Y of Central Maryland already operates 10 centers, in Baltimore City and Baltimore, Howard, Harford and Carroll counties.
