Busan National Sports Center is a gym next to Gudeok Stadium in Seo-gu, Busan. It runs paid facilities for weight training, swimming, aerobics, tennis, and table tennis. On weekends, free swimming opens at 6 a.m., and from 6:30 to 7:15 a.m. people have to line up. The facilities are old, and the showers and changing rooms are poorly maintained.
