The gymnasium with a pyramid-shape roof has two stories with volleyball, basketball and badminton courts on the ground floor.

Choe Un Sim, a guide of the gymnasium, told KCNA:

Trampolines and mountain-climbing practices are very popular among visitors.

On the first floor, there are a bowling alley and fitness rooms equipped with body-building apparatuses.

Han Jong Nam, an officer of the Korean People's Army who took part in building the water park, told KCNA:

At the beginning of the project, the construction of the gymnasium was not planned.

When the respected Marshal Kim Jong Un dropped in at the construction site of the water park, he said there would be sports enthusiasts among the visitors to the water park, so it would be good to build a gymnasium in the park for them.

After receiving his instruction, the soldier-builders built this splendid gymnasium in a little more than one month.

The visitors to the Indoor Wading Pool can also build their bodies with over 10 kinds of sports apparatuses in the fitness rooms.

Ryu Song Il living in Mangyongdae District, Pyongyang told KCNA:

Body-building apparatuses are excellent. I feel refreshed.
