This is a long workout- 78 minutes. I found it interesting that the pregnant background exerciser, Alison, didn't show modifications, but the other one (not pregnant) did show some (not many, however). Alison is obviously in good shape.
It definitely is not targeted towards pregnant exercisers. However, I found it manageable for a fairly complex step tape (choreography-wise). The intensity is high intermediate if you modify the power moves to lower impact, and advanced if you include them all. I did the workout on a 6" step.
I breezed through the first half of the step cardio. The second half was more of a challenge. Since I've only done this workout once, I'm not completely sure if I was just starting to get tired, or a combination of the following: frustration due to more complex choreography, frustration due to more choppy editing in the second half of the cardio (some of you may have noticed if you own CIA workouts), and being tired.
At the end during the ab section I found it interesting that Alison did the crunches on her back laying flat on the floor. Until now I was under the impression that pregnant women should stop laying on their backs somewhere between 12-16 weeks. Anyway, I went ahead and did the abs on my back too (which I had stopped doing a couple of weeks ago) and I felt fine also. I still think it isn't a good thing to do.
Anyway, I was originally excited upon receipt of the DVD that there was a pregnant background exerciser, but she shows no modifications. If you are up for complex choreography and interested in trying something different, consider this. But if you're feeling totally lacking energy, you'll want a lower intensity workout.
