Because Kate Beckinsale is actually synonymous with "not getting old", we all want to know her fitness secrets-so they are here. But please note that they are not walking in the park.

Although she was satisfied with the results, the 48-year-old British star admitted that her fitness program was difficult. "I was very scared of it at first, did an incredible punitive exercise, and kept complaining about it," she told Shape in an interview. However, she eventually "feeled 100% better when I left. Exercise is basically nature's antidepressant."

The actress likes to have a fitness program in the morning and collaborates with celebrity fitness coach Gunnar Peterson. As early as 2016, the coach asked her to shape her body in her movie "Underworld: Blood War", which she performed five or six times a week. Crazy things on a motorized treadmill. That part is torture. But what I like about circuit training is that you never do one thing for a long time. When you reach the point where it is almost unbearable, it becomes something else."

Actress Van Helsing likes her vegetables, even though she is not entirely vegetarian. She told Shape, “I’ve been a vegetarian for a long time because I hate meat. But when I filmed Pearl Harbor, I didn’t have enough energy. The coach I was working with at the time said, “You have to start eating chicken and fish. ". So I did it, it helped me."

The British also don’t like fad diets, recalling how she used to add ketone-friendly coconut oil to her tea and was allergic to it.

There are some weird trivia about Beckinsale's diet: whenever she travels, she puts butter in her suitcase, especially Kerrygold grass-fed butter, because it is a bit hard to find. She tells people, "If I am going from one city to another, I will put some in my suitcase to make sure I have it. I am a lunatic traveling with butter."

The star said that she needs some fat in her diet, because without it, wrinkles will appear on her face. She recalled taking a low-fat diet while filming Pearl Harbor, and it turned out to be "too old". Then it must be true-butter does make everything better!
