Gym, anyone? Whether Sharon Stone is showing off her street style or taking a break from the Southern California heat, the Mothers and Daughters star keeps proving that age is nothing but a number.

The 58-year-old actress looked half her age as she sizzled in a new photo she shared on Instagram over the weekend, which showed her fresh-faced and smiling for the camera as she takes a dip in a pool and flashes her toned bikini bod. In the snap, Stone wears no make-up, has her blonde hair slicked back, and strikes a pose in the water while wearing a printed black-and-white string bikini.

"It's so hot today! #summer16 #staycool," the mom of three captioned the photo. The jaw-dropping snap came not long after Stone showed off her enviable physique in June at the Hotbed Benefit Gala in Tiburon, Calif., rocking a silver Tony Ward gown that included a diagonal cut out and revealed a ton of skin.

As for how Stone has kept her figure in incredible shape over the years, she told Shape in 2014 that she swears by total-body stretches, strength training, yoga, and dance, and no longer drinks alcohol.

Just one look at her in a bikini will tell you that Stone's diet and fitness regimen is still paying off. Way to keep the fitspo coming.
