What's a nice girl like you doing with a dirty game publisher like EA?
"EA Sports approached me because they know I like sport and I'm a really active person, so it made sense to hook up. I feel pressure to get into the gym. I'm aware that I need to be super super fit in order to do my shows, but I can never find the time to actually go train.
So what really helps me is that I can train in the comfort of my own home - doesn't matter what time I have to go work. It's really quite a high intensity workout. It's perfect for my lifestyle. So it made sense to work together."
You've done a ton of charity work. Is improving people's fitness an extension of that?
"I like getting involved in projects that have a message, and when it comes to exercise I think it's the single best way to make yourself feel good. I know that for lots of people it's a pain, and a lot of people would much rather be doing other things, but to have a healthy heart, a healthy lifestyle - it's like, healthy body, healthy mind! It kind of goes hand in hand."
Not for us. We think immobility is an under-valued pastime.
"What I like to say to people who don't want to go to the gym, that can't be bothered to go out and exercise, is try to do things that are fun, because if you're doing something that's fun, you're not going to feel like you're exercising. It's not a chore.
So obviously EA Sports Active is a great example, because you can play tennis, you can play boxing, you can race against each other, you can skateboard - there are so many fun activities in that game - in the comfort of your own home where nobody can see you, so if you feel self-conscious about your body, or you don't want to go to the gym because you don't feel comfortable in that kind of environment, it's the best thing to do."
And this is all "good for you", is it?
"It's a fact that in order to have a healthy heart, you must do one hour of cardio in a week. Now obviously I would advise people to do two to three hours in a week, but I think something is always better than nothing.
So even if you don't want to do a four hour workout, can't be bothered with that, just do twenty minutes - even if it's just going out for a walk, whatever it might be. Something is better than nothing. It makes you feel better, makes you feel more alive, keeps you alert. So yes, I like to support things that have a healthy angle to them, because I think it's probably the most important thing in this world."
Especially for people who spend a lot of time playing games, we suppose.
"Sure, I mean my 16-year-old little brother would come back to the house after school, he'd be straight on the Xbox, and after a while it started to bother me because all he was doing was living his life sitting on a chair, playing a computer game.
But that's the great thing about this - it offers you the ability to be active and not sit constantly for hours on end. It's a really good thing. And it shows that the computer companies are thinking out of the box and trying to do things which encourage children to get up and get active. It's very important."
There are 25 activities in EA Sports Active. Which is your favourite?
"I like the running one, because I used to do athletics while I was at school. I used to run for my county. So I love the athletics one because you go on an athletics track. And if you do it with somebody you race against each other. It makes it more fun because my competitive nature comes out. And once again I'm trying to beat her rather than worrying about how long I'm running for.
The boxing is a great one for women, because I think you really work out without really realising how much you're doing when you box."
Does the game scale well to different ages? Could our granny play it?
"I would imagine so. Depends what she enjoys doing! You can do gentle arm exercises. On the athletics track, you don't have to be running full out - you can do a gentle jog, you can walk. My nan loves walking, she walks her dog an awful lot. So I wouldn't expect my nan to come round and start playing tennis on EA Sports Active, but she could probably do the walking, yeah."
We hear the game gives you dietary advice. Sounds unpleasant.
"It gives you tips on the right food to eat, yeah. You have your own personal trainer within the game, that guides you. Which is fantastic, because a lot of people don't know what to do, they're not quite sure what foods they're supposed to be eating. So it gives you all that advice - it's basically somebody in the screen looking after your needs. You put in all your information, and it gives you an answer back."
Besides the default stuff, you can tailor-make your own fitness regime, correct?
"You can create your own activities and each day it tells you how many calories you've burned. And it gives you a daily progress report. You can set yourself a weekly program, and follow the progress of that week, with differents settings each day. So you can see what you've done, what you've burned off, what you need to do.
And it's great. It's as if your personal trainer were physically there in front of you, giving all the information you need throughout the week. You could set yourself an easy workout, a hard intensity workout - it depends on your personality."
What does your own weekly program consist of?
"I don't need a program as such because I'm not counting calories. Again, it depends on what you're trying to achieve. I'm not trying to work out how many calories I'm burning, plus when it comes to diet tips and stuff I kind of have that down. For me it's really kind of a simple thing. I put on the running program, and I do that, or I might do some tennis, or some boxing. I like to change it up every day, that suits me."
