Taekwondo in Seoul: Sangrok Gym, (http://www.sangrokgym.com).
World Gym, 765-2 Yeosam-Dong, Kangnam-Gu, closest metro is Hanti. The gym is OK, equipment is very 80s but has dumbells which go upto 50 kg, two smith machines and a couple of benchs among other machines. Not good by Western standards and not as good as Chicago fitness club in Busan but definitely good enough for short term training if you are staying in Seoul.
