Ralph Macchioplays a father of two in thehit Netflix seriesCobra Kai— and it’s a role he plays off-screen, too.

More than three decades after he became a teen idol in 1984’sKarate Kid— theage-defying star, 59, was actually 22 at the time — the actor is now embracing a new generation of fandom thanks to the success ofCobra Kai,whichdebuted its third seasonon Jan. 1. His real-life son Daniel, 25 (yes, named after his character!), and Julia, 28, are among those fans.

“Part of the beauty of the success ofCobra Kaiis how much my kids are enjoying it,” he tells PEOPLE in this week’s issue. “To bring something that was such a big part of my life 35 years ago, and see it be such a present part of their lives today, it’s really wonderful.” But, he adds, “I’m still a nerd dad!”

Macchio creditshis wife of 33 years,nurse practitioner Phyllis Fierro, and their children with helping him maintain a “one foot in, one foot out” approach to Hollywood.

“Without her and without the foundation and the family we established, ‘one foot in, one foot out’ would have been very, very difficult on my own,” he says. “Because there would not be balance.”

But he also acknowledges the challenges of parenting.

“You’re skinning your knees like it’s the second day of first grade,” he says. “‘Failing’ is probably the wrong word, but you are learning all the time through the journey.”

“Everything I do now, more often than 10, 15 years ago, I’m thinking of it for the sake of my children as they’re getting older,” he adds. “They’re adults, but they’re always your kids.”
