Ubisoft's Women's Things

Well, sort of. The map of my body makes my thighs look like overstuffed sausages. I mention this to Wallon. "We're still working on improving this design," she says. I say the same thing about my thighs.

You can't fault Your Shape in terms of thoroughness. It scans everything from your biceps and triceps to your hamstrings and abdominals. It can gauge bone alignment. It can tell you your height, arm length, shoulder span, leg length and more. It probably knows what you had for dinner last night and which member of Girls Aloud is your favourite.

Your Shape uses all this information to help determine what kind of exercises you should be doing and how hard you should be working. "There are about 10 levels of difficulty, so it really adapts whether you're a beginner or you're already going to the gym," says Wallon.

The core of the game, or fitness software, or EA Sports Active rip-off or whatever you want to call it, is the Personal Training mode. This allows you to work on a certain area of your body by following a specially designed exercise programme. Or to be specific, by following the actions of a computer-generated personal trainer. I have a go, trying out a minute-long round of knee thrusts and squat punches. It feels exercisey, but my thighs remain sausagey.

The Fitness Classes train you in the art of things like yoga and tai-chi. Kinect tracks the movement of your joints and limbs and a diagram in the top-right corner of the screen shows whether you're doing the moves properly. This works well; it's good to get constant, real-time feedback, rather than just having to hope you're sticking your leg in the air in the right way. According to Walland, more Fitness Classes will be released as downloadable content after the game is out.

And finally there are Gym Activities. This is where you'll find more casual exercises like hula hooping. I have a go at cross-punching and kicking some virtual coloured bricks. This is virtually impossible at first due a massive lag problem, but Wallon assures me this is a temporary issue - something to do with the demo code reloading data.

Things do improve on my second attempt, but something's still not quite right. It's not just because a little bit of lag remains either. It feels odd to be punching nothing but air while watching solid-looking things explode, and it's strangely unsatisfying.

Still. Ubisoft has a few months left to sort out any issues with Your Shape, and indeed any with the rest of the games being demoed at its recent showcase. I know I speak for all women when I say some of them look a bit rubbish, and some of them look quite good, but nothing compares to Just Dance 2.*
