Even after retiring, Los Angeles Lakers legend Kobe Bryant wakes up at four o'clock in the morning to work out.

In a wide-ranging interview with Lewis Howes, Bryant, among other things, discussed in detail how he has adjusted from 20 years of playing professional ball to working on other endeavors outside of the sport. When he was still playing, it was relatively easy for him to wake up at four in the morning because there was a tangible goal.

“There's several factors for that, like when I first retired, I let myself go a little a bit … and then the challenge was, can I get back in shape?” Bryant said. “And it's really hard because there's no end goal; I'm not training for anything. So how do you motivate yourself to do it? For me, it was, okay, I have to aim for something. I said I want to aim for size, I want to aim for bulk. So that's a tangible thing, I'm gonna go for that.”

Now, as he's spending more time with his kids, teaching them lessons in life is his prime concern. And for Bryant, whose work ethic is considered legendary by most, he still wakes up at 4 a.m. just to show his kids the value of hard work.

“Your kids can't see how hard you work. You go to the office, I come to the studio. They don't really see the effort,” Kobe said. “So how can we teach our children what it means to work hard? You do it through training.”

“When I get up in the morning, my daughter goes with me. 4 a.m. My 15-year-old goes with me,” Kobe said. “She goes with me before school and it becomes a daddy-daughter thing.”

Indeed, Bryant's Mamba Mentality lives on even after his NBA days.
