It depends really, does she like dance games in general? If she's not a huge fan - and she doesn't do Zumba in real life - then she might find it difficult to get into a Zumba game, as the routines can be quite complex and it can be easy to give up on them if you don't have some natural ability. Your Shape is good for more general exercise as it has a wide variety of activities, from cardio to yoga, and it tracks your whole body so it knows what you're doing wrong (and when you're cheating!). One thing I would advise if she does get this game is to wear quite tight clothes while using it - for some reason Kinect doesn't cope well with baggy clothes and can think you're not hitting your marks even when you are.
