Michelle Pfeiffer

To pull off her sexy, slinky turn in 1992’s Batman Returns,

Pfeiffer did months of gymnastics, kickboxing and yoga — plus, she learned how to use a bullwhip like a pro! (Director Tim Burton once said she was “better than her stunt people.”) Thirty years later, the actress, 63, remains in killer condition (and can still use the whip, as demonstrated in a 2019 Instagram video), eating a paleo-inspired diet and hitting the treadmill for early-morning workouts. “It’s simple,” she’s said of her wellness philosophy. “Eat well, exercise and get lots of sleep.”

The former vegan — who does yoga and Pilates — eats lots of lean meats, fruits, fish, vegetables, nuts and seeds.
