Brooke Shields, 54, wows followers with gravity-defying ab workout

Actress Brooke Shields may be in her fifties but that certainly hasn't stopped her from being at the top of her game as far as her fitness is concerned. If anything, she appears more determined than ever to push herself to new limits

In fact, as part of the 54-year-old's latest Instagram post, Shields shared a video of herself in the middle of a workout with her trainer at Iconoclast Fitness in New York.

But what was ultra-impressive about this particular fitness routine is that the Blue Lagoon actress was doing crunches while suspended in the air, using her legs to hang on to her trainer for support.

Check out Brooke Shield's impressive gravity-defying ab workout routine:

"Defying gravity at the gym today. Still feeling the burn," Shields captioned the clip.

As part of the same post, Shields included a second video in which she is seen hanging upside down while doing squats.

Needless to say, both fans and high-profile friends of the actress commended her for her strength and fitness.

Jaime Camil, a co-star for her guest role in Jane The Virgin, responded with a simple clapping emoji and a raised hands emoji. And Shields's Law & Order: SVU co-star Ryan Buggle left three muscle-flexing emojis.

And fans were just as keen to shower Shields with some much-deserved praise.

"Yo yo yo, d second exercise is terrifyingly hard...hats off to u," wrote a fan along with three clapping emojis.

"Wow, wow, wow! You’re making us 50’s gals proud! Well done you!" added another enthused follower.

"What a privilege to hold brooke shields as she does full body crunches near your soul," added a third.

"Wow!!! You definitely Rock on, lady!" raved another. "That's really impressive."

However, not everyone had such positive comments to make about the routine, with one person suggesting: "That can’t be good for your knees."

And clearly proud of her incredibly body, Shields later posted a bikini snap to her near-900,000 followers.

She captioned the snap above: "another blue lagoon" - a reference to the movie Blue Lagoon that made her a household name.
