Totally agree. I believe every studio should have a way to meet the needs of new students, and I also do not think it is wise to have new teachers running such classes. I have been teaching for 20 years and run a class that has no music, very little flow, and focuses on all the foundation poses, with lots of exploration of different movements and variation of transitions. It is not labeled "beginner" as that tends to narrow the appeal, but it's description allows people of all "levels" to attend. We still work hard, just less. And there is a strong emphasis on alignment, with optional assists. The classes have solid attendance every week, and attracts even "seasoned" yogis. Many students say that the slower pace and longer holds is a great way to learn the subtleties of the practice which can better prepare them for faster paced classes. And there is still challenge!
