At Sogang University, behind K-building. It is a little bit difficult to find. If K-building is on your left and the gymnasium (체육관) is on your right, proceed in-between the two buildings down a steep hill. Just as the hill levels out, there will be a set of stairs on your left which run parallel to the length-wise back side of K-building, at the top of these stairs, you should already be able to see the pull up bars. There is also a set of parallel bars.
