The Underworld star, who turns 44 this month, told Shape magazine that in addition to hitting the gym and eating a healthy diet, she stays far away from alcohol.

“I don’t drink alcohol,” she says. “I feel [its effects] very quickly, so I’ve never actually had an entire glass of anything alcoholic.”

As for those workouts, Beckinsale works with celebrity trainer Gunnar Peterson five to six days a week, doing a mix of circuit training and cardio.

“I do circuit training interspersed with brutal cardio, such as crazy things on a nonmotorized treadmill. That part is torture,” Beckinsale said. “But the thing I like about circuit training is that you’re never doing one thing for very long. You get to the point where you almost can’t bear it, and it changes to something else.”

The British superstar and her 17-year-old daughter, Lily, eat super clean: lots of chicken, fish and veggies.

“Lily and I eat clean,” she said. “We have a lot of sautéed vegetables like Brussels sprouts and broccoli and chicken and fish.”
