clubs or circles

Have you already decided what club or circle are you going to join? Well, I am not, having hard time deciding the two of which to choose; ballroom dancing club or international exchanging circle. I have a feeling that I want to do sports, as I belonged to a sports club in my junior high and high school. At the same time, I want to enjoy talking with many people, and improve my communication skills. I thought about joining both club and circle, but I think that will make me exhausted... Well, I haven't been to either one for explanations, so I think I will decide what club or circle I'm going to attend after hearing them.
