thanks everyone!!
i wasn't aware of the promotion (it's not really advertised) until i was nearing the end of my first $99 initial month and one instructor mentioned it. i can see why they do it now, bc they figure they can really get ppl hooked with 2 months unlimited! even without it though, i would have still bought the 12mo membership.
anyway i am lucky that the studio is very close to my work..today i went during lunch.
also, should check out the new Empower class, it is great to get cardio in. it's also only 45 minutes.
