Sister Wives’ Kody Brown on Aging Gracefully for Robyn Brown

And as Robyn put it,, she’s simply grateful that her husband of 11 years was taking care of himself. 

“I feel like Kody working out is kind of icing on the cake,” the 47-year-old said. “But really, what is the core of it is who he is as a person.”

And while the workouts are appreciated, Robyn confessed exactly what it is about Kody—who also split from wife Janelle Brown in recent years—that she loves that most, saying, “Something that really always makes me just go ‘rawr’ with Kody is when he’s a good dad.”

Still, when it comes to being a father, Kody is well aware that he could have done more for his 18 children. 

“I should have had a strong relationship with my children,” he admitted while competing on Special Forces: World’s Toughest Test in November. “I’m in a place in my life now where I’m very willing to say that I’ve been wrong.”
