Hi Nancy!
This may or may not help, but I just wanted to say that when I was pregnant, I tried Kathy Smith's Pregnancy Workout, as well as Jane Fonda's and Denise Austin's. Seems like I rented them from the county library. If you are new to working out, you will probably like them and also you will probably get a decent workout. However, if you have been working out for awhile and are already in good shape, they may not be challenging at all for you. I had been working out before my pregnancy, so I did not break a sweat during these videos. But I did learn some breathing tips and stretching from Kathy's and Jane's that I liked. Plus, just working out with some other pregnant people made me feel good (even if they were on tv). I am looking thru the collage video brochure, and it looks like Buns of Steel Pregnancy Workout, item #2382T, was done in 1994. At least that one is newer. The video's above that I tried were quite a few years old and the clothes were kinda funny. I guess that shouldn't matter, but for whatever reason, I kinda wanted something newer. Although the clothes are out of date, I believe all of them are approved by the American College of Gynecologists, so the info is probably still very good.
Good luck to you.
Lisa
