Has anyone taken Prenatal Yoga classes? I already belong to 24hr Fitness and wonder how different the Prenatal Yoga classes really are? I think I'm going to buy a package for 5 classes at a yoga studio to try out the Prenatal Yoga (and try to make some mommy friends) but it seems just like an additional expense.

Could you do a lot in the normal yoga classes with just a few modifications do you think?
