I own it on video, and found it to be disappointing. The salsa aerobics didn't feel good on my pregnant body. They were actually annoying in general.
The "yoga" part wasn't much of a workout. Leisa Hart breathes very loud during this section, which was irritating. I've seen better reviews for her post partum workout; however, I haven't tried it.
I didn't use any pilates videos while pregnant, so I can't offer any opinions in that area.
