What message do you want to convey on in your second year as the face of International Fitness Week?
Working out is easier and more effortless than you actually think, you just need to find the right workout to suit you, whether it be a walk round your estate, doing my fitness DVD, or going to the gym and learning about fitness and gym equipment. You just have to make it part of your lifestyle. As a starter aim to work out at least two or three times a week – I don’t do any longer than an hour. Mentally it makes you feel good, it lifts your mood, you start to see the results in your body, and you actually have more energy.

Your physique is infamous, how do you keep in such great shape?
I work out, you have to make an effort. You have to be focused and consistent, there’s no point working out like a mad hatter for a few weeks, then never working out again, you have to make it realistic.

Your killer abs are particularly famous, do you do endless sit-ups?
I do about 600 sit-ups twice a week. It’s not easy but I change my position every 10 reps for variety.

How does your exercise regime vary?
I’ll do anything from an hour’s hike, my workout DVD, a run, light weights, or I’ll take an aerobics or a circuit class. I really vary it to keep me interested, I couldn’t do the same thing two or three times a week, that would drive me mad.

How did you keep up your fitness regime while you were on tour with the Spice Girls?
I’ve only really got into working out after my last baby, so in the last two years. I guess before I was running around on stage and working hard, whereas now it’s kind of been intensified as a more specific workout. I feel the fittest that I’ve ever felt right now, more so than I did ten years ago.

How did you find being a role model as a Spice Girl?
I’ve never really seen myself as a role model, I’m hopefully a good example for my kids and if anybody else wants to see me as a role model then I’m flattered.

How did you feel about going back on stage for the reunion tour?
It was absolutely amazing; it was the best thing all of us have ever done because this time round all of us really appreciated it even more. And our kids got to be a part of it – which made it even more special.

Did you up your fitness regime to get in shape for it?
I was rehearsing for Dancing with the Stars while I was doing my Spice Girls rehearsals – the last show of Dancing with the Stars ended on the Saturday and I was on tour on the Tuesday, so it kind of all fused together.

What inspired you to get fit after the birth of your second daughter?
I just wanted to be fitter. The older you get the more mentally you have to look after your body and what you eat. I just thought if I’m eating healthy I might as well work out as well and make it part of my lifestyle. I always work out with friends so I can have a gossip and get fit at the same time.

Do you encourage your girls to have a healthy lifestyle and get outside?
LA’s got the perfect lifestyle to keep them healthy – my 10 year old is hugely into basketball, and her skateboard, while my two year old just loves running around in the park. They play together with my five year old step-daughter. It’s important to encourage your children to make use of free parks and places where they can run around and kick a ball, there’s plenty of them in the UK too.

How do you think living in LA has affected your fitness regime?
It’s definitely easier, you wake up and the sun shines all day, every day. In LA people are fitness driven so it’s easier to join in.

How do you motivate yourself?
My friends, it’s way more interesting to exercise with friends.
