I liked Zumba, I sweat so much!
I wish my gym was as cool as yours sounds

I could stay on a machine for so long if I could watch TV. Actually when I get home, I plan to rig something like that up for the crappy exercise machine I have in my dogs room... Maybe I should make it so that I can't watch TV unless I am exercising... That might be motivating.
I like the Bodypump class... Hardcore!
Anyway, Good luck with the gym, and in no time your body will get vicious
