Update 13+ weeks later:
5 weeks into the yoga class, other things in life got really busy and I had to cut back training to like 2 hours a week, so there went regular yoga. When the musical concert season entered full-speed, I had to cut that out, too, with 3 hour rehearsals and performances 11 nights out of 14.
I'm re-taking the class starting in a few weeks, and it seems to be designed for this. To try to keep up a little, I bought some books. It's amazing how different Iyengar is from some other styles. My teacher is a stickler for form and for staying in an asana long enough to feel how to relax when in it. One of the books I bought (by Cynthia Worby) seems to follow this and models the form I was taught. Some of the instructions for achieving an asana are the same as in my class. Another book by Zack Kurland focuses on morning workouts (vinyasas?), and seems to move you from asana to asana at a rather quick pace - 15 asanas in a 20 minute sun salutation warmup or beginner vinyasa. So far I think I'll stay with Iyengar and Ms. Worby when I'm not working under my class.
Like that bandha site!
