Fitness studio for foreigners in Seoul?

Hi there,

I got a hard time finding a fitness studio with English speaking staff / for foreigners in Seoul, at least from sheer online research. I only found one or two very pricey ones, that on top of that are more spas than actual fitness studios! I also asked around elsewhere with no success!

So, does anyone know fitness studios with English-speaking staff? This is my first priority now, so even if it's pricey or has some issues from your point of view, I'd be happy if you'd name it still!

Thanks in advance.
