The year may be winding down, but Brooke Shields is not.

The 54-year-old put her impressive fitness regimen on display while working out with her trainer.

In a clip posted to Instagram, the “Jane the Virgin” alum did crunches while suspended by her trainer with her legs hooked behind his arms.

"Defying gravity at the gym today,” Shields captioned the video. “Still feeling the burn.”

Then to really show off her dedication, the mother of two included a video of herself hanging upside down at the gym while harnessed into a pair of gravity boots and performing inverted sit-ups. Do not try this at home!

Many of Shields’ celebrity friends offered praise for her inspirational training.

Supermodel Helena Christiensen wrote, “I have unleashed a Beast!!”

The president’s ex-wife Marla Maples added, “I’m coming over! You look great girl.”

While Cindy Crawford kept it simple by commenting with the strong arm emoji.
