The Tracy Anderson method
Cheryl Cole is set to make it big in America - but despite being super slim already, she seems to be worrying about what living in the US could do to her figure.
Just 24 hours after landing in LA to start working on US X Factor, Cheryl hit the gym for a workout with personal trainer Tracy Anderson.
Tracy is already famous for working with celebs like Madonna, Gwyneth Paltrow, Nicole Richie and Jennifer Aniston.
If you'd like a tiny figure like Cheryl's, but can't afford to hire Tracy yourself, don't worry - Tracy has her own exercise DVD that you can do in your own home. And best of all, you can see a clip of it here!
The Tracy Anderson method: Dance cardio workoutIt's an all-over body blast, made up of fast-paced dance routines to thumping dance tracks.
It's not for beginners, but if you love dancing and already have a fairly good fitness level, she'll be perfect for you.
Tracy's theory is that reps result in 'bulking up', so the varied moves mean the toning and shaping is balanced all over your body.
Tracy first breaks down the routines for you to learn, which is a good workout on its own, before going into the full-paced versions. You can choose to follow the routine with Tracy facing you, or facing away from you as if you are in her dance class, depending on what's easiest for you.
It's an advanced workout, but if you are looking for a challenge and quick results, it's definitely worth a try.
