Ronda Rousey, the MMA’s most dominant fighter, recently released her first book, My Fight/Your Fight, in which she gives a glimpse of her life story.

Ronda Rousey On New Book

“It’s not really a memoir and it’s not really a self-help book,” Rousey said on Good Morning America of her book. “It’s a little bit more a mature themed book. It’s a life story and life isn’t PG rated.”

Among the topics Rousey covers in My Fight/Your Fight is her family life, which included the early loss of her father. “We lost my dad, and that was a hard time, and my mom had all of us to take care of by herself, which was really hard for her,” Rousey said.

Rousey has nothing but love and affection for her mother, who had been a judo champion before having her. Her mother’s experience as a fighter may have made her a bit less sympathetic of Rousey’s injuries, but is all about nurturing her UFC fighter daughter if she’s ever ill.

“My mom if you’re sick is like the most nurturing, sweet, beautiful person. And it’s funny with the injury she’s like ‘Walk it off!’” Rousey joked. “But if you cough she’s like, ‘Oh, my baby, are you okay?’ So the second I get sick, I’m like, ‘Call mom, it’s nurture time!’”

After winning a bronze medal at the Olympics, Rousey had found success despite the odds. But, it was soon followed by a stint of homelessness. Rousey, who was born with her umbilical cord around her neck and was unable to speak until age four, believes that the tougher times in her life have made her a more interesting person.

“Easy lives make boring people and things have definitely not been easy,” Rousey said, spinning what could be a negative into a positive. She did the same thing when asked about her portrayal as something of a villain in UFC circles.

“The thing is, the antagonist is the person that drives the story. The protagonist just reacts,” Rousey reasons. “If it wasn’t for Lex Luthor, Superman would have sat around all day.”

My Fight/Your Fight is currently available in hardcover and e-book.
