Sport club

One of my friends recently joined a sport club and took me there as a guest.
I am not interested in joining the sports club because I think running on the machine is boring and I would not go there often if I join it. Actually, when I was in Japan, I joined one but I did not go at all and just wasted money and that made me feel bad.
I found out some difference between Japanese sport club and the one my friend took me today. The pool was righted up in the blue colour and made people relax and the swimming wears are more casual. Most girls ware bikini and nobody wear hat and swimming glasses.
At Japanese sport clubs, people never wear bikinis there and have to put swimming hats and goggles compulsory otherwise some staff would take us out. People swims eagerly and do not talk much because they come to swim. If people really just want to swim, Japanese club are perfect, I think.
