Hi There,
I would suggest getting the Kick, Punch, and Crunch//Legs & Glutes DVD for sure (I only have Kick, Punch, and Crucnch on VHS, and it is one of my alltime favorite cardio videos of Cathes. I like it so much more than Kickmax b/c it really works you hard the whole time, it targets the waist and legs. I don't have Legs & Glutes yet, but everyone says in their posts that the DVD of the two of them has AWESOME premixes).
Then, if I had to choose one other, I'd go with either the Pyramids or Boot Camp with Muscle Endurance. You can't go wrong with either. The reason I didn't pick IMAX2/Cardo & Weights is that, although they both have the fun factor, after Hardcore they just don't seem as tough anymore. But they are fun!
BodyMax is a great workout, but as someone said, it is long, and the music is real old--I definitely enjoy Bootcamp and Upper Body Pyramid more.
Good Luck!!
Melissa
