New to the site

¿Que tal chicos? I'm a 20-something, female English teacher, new to the forum, but I've been living in Buenos Aires for about 5 months now. I've lived in such diverse parts of the city as Villa Lugano and Las Cañitas, and now I'm living in Belgrano until July.

Any advice on good gyms in Palermo and/or Belgrano? I'm looking for group classes and a friendly atmosphere . . .
