I think I was "too advanced" for the class I took (I've not been in yoga long). It seemed more of aVERY basic yoga class, very slow. I didn't even get warm. I plan on trying a hatha yoga or vinyasa yoga class next.
The room was noisier than I'm used to as well.
I felt bad walking on the floor with my shoes - I'm used to having a cubby for my things, not placing them on the floor beside me.
I didn't see any of the usual props for a yoga class (except a very blocks).
