My first yoga class was a vinyasa class a little easier than the one you describe. Overwhelmed by the array of choices before me, I asked my brother the yoga instructor to recommend one. He said "try the vinyasa -- it'll be a good workout". The instructor had a thick French accent; not only didn't I know any names of poses, it took me three weeks to figure out what "lunch pose" might mean.

Poor girl. I hope she finds her level faster than I did!
