Whiteley has an amazing set of abs, and she makes sure to work on them. She says that Pilates is a go-to ab workout for her. “I have to really work on my stomach," she toldHarper’s Bazaar UK. "I've found Pilates great because it's slow and controlled and you really have to think about the muscles you're working."

2. She Eats A Balanced Diet

When it comes to her diet, Whiteley makes sure to have a balance. She opened up about her diet in her Harper’s Bazaar UK interview. “It's hard, because I'm travelling a lot and I don't have a routine to my life, so I'm often eating out or ordering room service. When I'm at home I try and cook very clean, very basic foods. When I'm out I'll enjoy myself, but there are ways to make healthy choices – there's always fish and chicken and salad. If I have a lingerie shoot or a red-carpet event coming up, I might cut out carbs, watch my salt and sugar intake and drink even more water for a few days before.”

3. She Reduces Bloating

Whiteley’s amazing abs aren’t just because of Pilates. She also makes sure that she isn’t bloated. Whiteley shared her tips with Harper’s Bazaar UK. “I always find that when I've not been drinking enough, I get more bloated. It sounds counter-productive but drinking more water will actually get rid of the water retention. Probiotics are great for keeping things moving as well, I throw them in a smoothie or take them in pill form.”

4. She Takes Care Of Her Skin

Whiteley told Harper’s Bazaar UK that skincare is extremely important to her. “There's no point putting on loads of make-up if you're not investing in healthy skin,” she explained. “So, it's really about working out which products work for you. It can take time and trial and error and, believe me, I've been through it all. I'm very loyal to a product from IS Clinical called Active Serum which has changed my skin, and my aesthetician in LA, Shani Darden, has a fantastic retinal cream called Resurface, which is great for fine lines and dark circles and gives you that even skin tone we all want. I also try and wear sun cream everyday on my hands and face.”

5. She Does Body By Simone Classes

Whiteley likes to do a lot of dance-cardio workout classes. She tells British Vogue that she likes to go to Body By Simone classes in particular. "I love it because it’s a very female positive environment,” Whiteley explains. “You’re dancing and the music is blasting and all the instructors are training alongside you. It’s fun. And I see results very quickly."
