I've had a very productive evening so far. I've done half an hour of my Zumba game, it's bloody brilliant I love it, I only went on to try it out and ended up doing 6 sets, I feel like a total prat doing it but with the blinds shut no-one can see! The figure of myself on screen is nowhere near as hideously scary as it is in the Biggest Loser game, I'm relieved you don't need as much room as I thought.
I've also done the first work out on the EA Active Sports 2 which is also great, this was the one I was really worried about because it was expensive and I was scared that my livingroom would be too small.
I'm glad I haven't wasted my money, I might just have to try a recalibrate the Biggest Loser game to get it working right!
