If Brooke Shields's latest Instagram post is any indication, age is nothing but a number.

The 54-year-old actress shared a video of herself and a trainer at Iconoclast Fitness in New York, showing off her incredible fitness skills.

The clip shows Shields doing crunches while completely suspended in the air, hanging on to her trainer and using her legs as support.

"Defying gravity at the gym today. Still feeling the burn," Shields captioned the clip, which she shared with her 898,000 followers on Instagram.

And as if the first video weren't impressive enough, the former Calvin Klein model also included a second video that shows her doing an inverted squat while hanging upside down with her feet in gravity books.

Fans and fellow celebrities were quick to praise the star’s show of strength. Jaime Camil, whom Shields acted alongside during her ‘Jane the Virgin’ guest role, left a clapping emoji and a raised hands emoji. And Shields's ‘Law & Order: SVU’ co-star Ryan Buggle commented with three muscle-flexing emoji.

The comments from fans were just as positive. "Wow, wow, wow! You’re making us 50s gals proud! Well done you!" one person commented.

"You are a superwoman," another person wrote.

The ‘Blue Lagoon’ actress subsequently shared a picture of herself standing in the ocean while wearing a blue bandeau-style bikini with string-tie bottoms, showing off her incredible, gym-honed physique.

In the picture her long brown hair is slicked back and she appears to be wearing no make-up, simply a pair of stylish aviator sunglasses with purple-tinted lenses.

“Hello gorgeous!!!!!,” was one follower’s response in the comments section, while also simply left flame emojis.
