Kate Beckinsale

Kate Beckinsale, the iconic vampire slayer of the “Underworld” franchise, has traded in her stake for a sun-kissed bikini. Decked out in a lime green bikini, Kate Beckinsale proves that a commitment to health and fitness can turn back the clock. Since 2018, she has sculpted her already impressive physique with a steady mix of yoga and strength exercises that prioritize flexibility and core strength.

Her approach to eating is just as disciplined—think plenty of proteins and veggies without torturing herself with unrealistic diet constraints. No wonder she looks fabulous at every beach outing or poolside appearance, proving that age is just a number when you’re as dedicated as she is.
