Kody Brown is looking to keep himself young.
The Sister Wives patriarch shared insight into this fitness routine, confessing that he works out as much as he does in order to keep up with wife Robyn Brown, who is nine years younger than him.
“I got to keep myself young,” Kody explained while going through a rigorous workout routine on the Dec. 14 episode of the TLC series. “I don't want to be the old man in the family.”
He added, “I'm really trying to focus on aging gracefully. Strength training simply for the purpose of just staying well and healthy.”
The episode also saw Kody show off his impressive workout skill for Robyn, joking that he wanted to see how many pull-ups he could manage with “a beautiful woman watching me.”
And the 56-year-old’s dedication to keeping himself fit is something ex-wives Christine Brown and Meri Brown have both noticed.
“Kody always was obsessed about working out,” Christine mused on the episode. “Always obsessed. It was an obsession, I thought.”
Meri added, “I don't remember him working out in our early years of marriage as much as he does. Now he's in pretty good shape. He works hard.”
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."
His failures, he continued, were "were because I didn’t know s--t about being a dad and husband and I thought I did. I really thought I did and I misunderstood that and I did it wrong in so many ways."
However, the reality star “hated being blamed” for what he considered a failure, and was “resistant to ownership” for a long time.
"I would like to repair all the relationships with my family and even my ex-wives," he acknowledged, "and that’s not easy."
Sister Wives airs Sundays at 10 p.m. on TLC. For a deep dive in Kody and his expansive family, keep reading.
