Live Kinnect Games, Question on downloadable Kinnect games Options

[Reidmere]

I just recently got further out of the dinosaur age (had a Wii and PS2), and moved up to a 360
(getting a PS3 too, for working on someone's computer).

Now that I'm coming out of my cave, I need to know the types of flowers around, and what I can eat.

Right now, I don't have any money to spend, but got a bunch of XBox Live credits from the local arcade.
(Put it this way: I walk in there with $5, they know I'm leaving with at least 1 jackpot).

So, I'm looking for a fitness type of game that I can download from XBox live, with my credits.
So far, I've downloaded Dance Party and Just Dance demos, and the UFC training demo, but I don't really know all of the games that are out.

We have Zumba Fitness: Rush already, and are looking for anything else that doesn't have to be a fitness game in itself, but one to get one's rear end off the couch. I want to get "Your Shape Fitness Evolved" when I get the money, but wanted something we can use sooner: But I don't feel like doing the Cha-Cha!

Thanks in advance!
