The 30-year-old star of TV's The Jump is famous for getting muscly by pumping iron.
Now she's passing on the secrets of how to get buff to the rest of us.
As well as finding fame on the box, Chloe, who dates fellow fittie and rugby hunk James Haskell, 32, is a nutritionist and qualified personal trainer with a figure to die for.
Millions of people are hoping to shape up in 2018 and in her new book, The 4-Week Body Blitz, Chloe reveals her personal daily exercise and meal plans aimed at transforming us lesser mortals in just 28 days.
The daughter of telly's Richard Madeley and Judy Finnigan, Chloe also starred in ITV's Dancing On Ice and says: "Four weeks can guarantee a body transformation for everyone. I started training properly five years ago now.
"I began my personal trainer qualifi-cations almost immediately after that, and every year since, I have found myself leaning more towards short turn-around body transformations.
"This is partly due to my own career as a fitness model and also because clients usually come to me with a timesensitive goal in mind."
Chloe believes a month-long regime can make a big difference whatever your shape and size, explaining: "When it comes to what results can be achieved it depends on the start point.
"For example, a size 10 could get abs in four weeks, but would probably only lose a few pounds. A size 16 probably wouldn't see abs in four weeks."
To see results, Chloe recommends sticking to a strict diet.

“Remember, that creating new habits is hard and it takes time.”

She says: "Eat clean, single ingredient foods at every meal - fruit, veg, chicken, fish, lean meat, nuts, avocados, oats, rice and grains.
"Have small portions. Calories are hugely important when it comes to changing your body with diet.
"I count calories but I tell my clients they do not have to track numbers, but they do have to be mindful of how much they're eating.
Chloe also advises carb cycling - having days with low and high carbohydrate foods to help shed fat while keeping the body strong for some intense training.
She adds: "Time your clean carbohydrates such as oats, rice and potato, pre and post training. The rest of the time, have fats alongside your protein and veg instead."
Chloe admits that even she has guilty food pleasures.
"If I could have one wish, it would be that I could eat pizza every day and not gain any body fat."
And during a monthlong body blitz, she says we should rein in our treats, too.
"Have them once a week maximum, it is important for both your mental and physical health to give yourself a day off every now and then."
Chloe enjoys a glass of red wine or whisky. She says: "When I do drink, I do so daily on holiday or around Christmas!

But, as many people try to cut down their boozing for Dry January, she adds: "I go months at a time without drinking. It's all about getting over the first willpower hurdle."
When it comes to training, Chloe doesn't cut corners, working out six days a week.
She explains: "Monday to Saturday, I do 40 minutes cardio at home and 40 minutes weight lifting at the gym. Sunday's my rest day."
But how do the rest of us achieve our diet and fitness goals?
Chloe says: "Pick a start date at least a few days in advance and stick to it.
"Tell all your friends and family that you are doing this. This does not mean telling you that one piece of cake won't hurt. It means telling you to be strong and remember your goals.
"Clear out the kitchen and replace all your favourite meals with their healthy alternatives such as milk chocolate for dark or Nutella for almond butter.
"This way, you will enjoy your food without falling off the wagon.
"Set a cheat night in advance. At the end of a four-week blitz, for example, plan a date night, and use that as a reminder that food isn't going anywhere, you're just being strong for a few weeks!
"Remember, that creating new habits is hard and it takes time. You will not achieve it if you are not tenacious!"
The 4-Week Body Blitz is out now priced £14.99.

TOP 3 EXERCISES
BURPEES
CHLOE SAYS: "Stand up straight with your feet together and your arms down by your sides. Come down into a crouch and place your palms flat on the ground in front of you. Put your weight on your hands and jump your legs backwards, so you are in a hand plank position.
Jump your legs back in, knees to your chest, so you return to crouch position. Explode up into the air in a jump, landing back in your starting position."
MOUNTAIN CLIMBERS
CHLOE SAYS: "Lie on your front, feet hip-width apart, toes facing towards the floor. Place your hands by the sides of your chest, palms facing the floor. Push yourself up by your hands and feet.
Bring one knee up to your chest and then back to the starting position. As you do this, switch legs, so you are performing high knees in a horizontal position. Continue for a full minute."
SQUAT JUMPS
CHLOE SAYS: "Stand up straight with your feet hip-width apart. Extend your arms out in front of you and place one hand on top of the other - alternatively, place your hands on your hips.
Keeping your back straight, lower yourself down into a deep squat by bending your knees. Instead of standing back up again from the squat, gently jump back into a standing position.
The jump should be so gentle you can maintain your form from the very start of the exercise to the next rep. It should be so gentle you only come off the floor a little. Jumps can damage your joints, so keep it gentle. Repeat for one minute."
