Hi Wendy,
IS, BB, of HC? What a terrible dilemma. Here are the reasons why each one of these would be great for you to buy right now. I'll let you decide what your priority is ;-)
HC: if you order now, you will get it cheaper than you will ever be able to get it again. Plus, once everyone gets their orders (in early Feb maybe??) you are going to be reading a thousand posts about how great they are, and wish that you'd purchased them. A downside is that many of these workouts might not be doable during pregnancy. Certainly IMAX3 and HIGH STEP CHALLENGE are out of the picture due to the anaerobic nature of the cardio; LOMAX might be perfect if modified. KICKMAX will require serious modification to take down the intensity (if it's anything like KPC). COREMAX could be of limited use, given the modifications that need to be made as your abdomen grows; planks and anything in the supine position are certainly out, as well as any crunches, etc that have you lying flat on your back. I also wouldn't thing V-Pikes would be very doable. STRETCHMAX sounds divine for the pregnant body, but you've already told me that you are avoiding yoga-type stretching, so you might not like this one. The weight workouts would probably be just great, if you were wanting to incorporate more of that, with the appropriate modifications. I doubt HARDCORE EXTREME will be a walk in the park, cardio-wise
So, overall, limited cardio with this series, probably great weight work, but most likely going to be terrific for post-partum.
BB: this series is fun, fun, fun, fun!!! The trillion premixes on these dvds, plus the TimeSaver, allow you to get a workout at any level, and many different lengths. It is ideal for pregnancy, when you want to modify, and post-partum, when you want to kick things up a notch. Plus, there are no interval workouts that will have to sit on your shelf until after the baby's born. You can use all of these workouts starting now, and they will carry you through into post-partum very well.
IS: A superb series, but not very useful during pregnancy. You will have to leave IMAX2, BootCamp, and the Terminator workouts on the shelf until post-partum, or modify them so much that they would unrecognizable. This would leave you with cardio from only one workout: Cardio & Weights. It's a great workout, and would serve you well, but it would be the only one you would get any use of right now. Cathe created this series to help her get back into shape after her second baby, so it very much reflects that.
Well, despite my best intentions, I think it's pretty obvious that I'm partial to you buying the BB series
And the music is fabulous!
Let us know what you decide!
