Query: Caused Abdominal Distress for Days

I have been practicing yoga for 10+ years, and this is one of my least favorite DVDs to date. First the set is awful. It looks like it must be in one of the girls' basements. The clothing is kinda... sloppy and doesn't match. I know I shouldn't care about that kind of stuff, and if the workout was stellar, I could overlook it. But the workout is simply not fit for a pregnant woman. There are too many poses that put a considerable amount of strain on the core. Consequently, I was felt overstretched (and nervous) after only 45 minutes of the laborious, tedious, and downright boring video. How the instructor managed to make a difficult workout so boring I will never figure out. As I sit here, I'm still nervous about the way my stomach is feeling. Wish I had never done this workout!!
