The tales of Kobe Bryant's work ethic during his time in the NBA have been well-publicized over the course of his career.
From his insane competitiveness during harmless scrimmage games, to pretty much staying up all night in the gym during the 2012 Olympics, Kobe's desire to better himself is almost unmatched.
But even after retiring over two years ago, Bryant is still keeping to the same training regime.
The legendary Laker recently sat down with best-selling author Lewis Howes for an interview, and explained why he continues to maintain a strict workout schedule.
"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."'
Kobe also admitted that his three daughters -- 15-year-old Natalia, 12-year-old Giana, and 1-year-old Bianka -- also served as motivation.
"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."
Bryant's eldest child has even joined Kobe on a few of his 4am workouts.
"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."
The Mamba Mentality must run in the family I guess.
