"Ant-Man" actor Paul Rudd (53) is one of those stars who apparently fell into the eternal fountain of youth. In any case, it is hard to believe that the "Sexiest Man Alive" of 2021 will be 54 on April 9, given his still youthful appearance. So why is Rudd holding up so much better than most of his male peers? In an interview with "Men's Health" he has now revealed his secret and revealed that it has nothing to do with hard training - quite the opposite.

Accordingly, he is asked at regular intervals about his nutrition plan, or: "How often do you train per week? Do you drink [alcohol]? Do you eat carbohydrates? Do you have a cheat day?" But none of these questions hit the mark, according to Rudd. Instead, he elaborates, "The most important part of training is sleeping." It has to be eight hours a day for Rudd's taste.

In his opinion, without enough sleep, even the most intensive training is useless. Taking extra naps so you can spend more time in the gym is the biggest mistake. In Rudd's view, these people would be "doing themselves a disservice". However, even Ant-Man cannot do without sport. After his eight hours in bed, he starts his day "with cardio before I've eaten anything."

Since 2015, Rudd has been mimicking the size-adjustable superhero of the Marvel franchise. In the past eight years, thanks to the role, he has learned a lot about his own body and its needs. Like MCU colleague Chris Pratt (43), he also had to get in shape with the help of personal trainers and nutritionists. In addition to a certain basic fitness, it also gave him mental stability – so that he felt “less like an impostor” as a superhero.

So Rudd's secret to eternal youth seems to be this: exercise, but don't overdo it - and hit your ears enough. Especially since there's always that one mountain of muscle that can't be avoided anyway, as the star revealed to "People" in 2021 with a wink: "I remember how it was on the set of 'Endgame'. I've trained so long and hard , ate perfectly, worked like a pro. And then I was standing next to Chris Hemsworth and I was like, 'What's the point? Why even try it?'"
