fun, dance-based fitness DVD - any ideas?

[PlateSpinningAtAllTimes]

Need to do some exercise once I'm fully recovered from giving birth in December, but ideally something fairly gentle (Shred has wrecked my knee). I thought something dancy would mean I can do it when the DC are awake - DS can join in and DD will like the music. That's the plan anyway!
Any recommendations?

Do you have a wii.....the just dance ones are quite good and the kids will love it too :)

Alas, no! It's something we'll probably invest in one day though when they're a bit older...

Zumba!
