I own the original pump it up DVD, and wanted something new, as I liked the original DVD a decided to buy another in the series and I'm pleased I did!
The first two times I did this workout I found it really hard to keep up, loads of rewinding to try and get the moves right, but after doing it a few times it soon sunk in, and I felt like I'd really achieved something by learning the moves (although still a couple I need to perfect)
The DVD is not as intense as the first MOS was, but often I prefer that, and I still feel like I've got a good exercise at the end. The toning section is brilliant, no push ups which I hate! Love the music too, really gets me in the mood!
I've been doing this DVD 2-3 times a week, all 7 sections, for about 2 months now and I definitely can notice a difference, I feel slimmer more toned and more flexible.
There are a couple of negatives, I agree with what others have said about the dancers not having as much of a personality, and also perhaps there is a bit too much of the 'base step' in between doing the dances, however, if they didn't have this I think I would have struggled a lot more in the outset.
Overall thinks its a great DVD and one that I've not got bored of, which is unusual for me!
