Fitness fanatic Gwyneth Paltrow parades her body in TWO thigh-high

She has been candid in the past about her grueling daily workout regime.

And it appears Gwyneth Paltrow is determined to display the results, even it means switching up her outfits in the space of a few hours.

The 40-year-old actress showed off her long muscular legs in shorts during a Good Morning America appearance on Wednesday in New York City, before flaunting her toned arms in a tight black sleeveless dress as she left the studio after the interview.

The Iron Man star wore tiny blue Rag & Bone pinstriped shorts paired with the brand's Jefferson Blazer as she promoted her new cookbook It's All Good on the popular morning show.

Gwyneth boosted her already tall 5ft 9in frame with strappy grey and brown heels, and added a formal touch with a high-collared white blouse.

The mother-of-two wore her blonde hair loose and straight over her shoulders and opted to keep her makeup natural, highlighting her blue eyes with smokey shadow and her lips with a rosy gloss.

Gwyneth then slipped into a sleeveless black knee-length dress that showcased her slender arms and tiny waist as she left the Manhattan studio.

The Rag & Bone frock, called The Piper Dress, featured beige panels on the hip and waist area, which had a slimming effect - not that the svelte star needed it.

Gwyneth wore pointy black heels and tied her hair back into a playful schoolgirl ponytail.

During the Good Morning America segment, the star demonstrated how to cook the turkey chili that appears in her book, which contains mostly gluten-free, low-carb recipes.

Gwyneth spoke during the interview about her own health problems, which motivated her to pen the healthy-eating tome.

'When you have young children and you’re working, you know, you never rest,' she said. 'It’s like you’re racing to get home. And my body sort of went kaput a little bit.'

'Then my doctor said you really need to clean up your diet and we’ll change all this blood work and it really worked,' she added.

Gwyneth said she cut out a host of foods, which helped her lose weight and boosted her energy.

'I thought I’d like to make a book that’s not as restrictive as that but that’s a little bit healthier and really, really good comfort food so you don’t feel like you’re cutting anything out. You know, that makes you feel better, lose weight and have more energy,' she said.

Responding to criticism about her comment that she deprives her children of carbs, the star said:

'People get things very wrong and don't open the book and see what is what.'
