Yoga Class & GYM (Santiago de Chile)

Hello All,

As i just moved to Santiago and do not have a Rut yet (cheers registro civil), i wanted to ask if anybody knows of a yoga course in las condes, where i can pay cash?
Preferably Iyengar Yoga, but i am happy with any other one,too.

Also, do you know a gym where you can sign up without a Rut? Tried the one above the W hotel but that´s way out of my price range..

thanks!
