Katherine Schwarzenegger, daughter of Arnold Schwarzenegger and Maria Shiver, is releasing an inspirational book for girls focusing on complete body acceptance. In other words, she "wants to pump you up!"

The life of Katherine Schwarzenegger, daughter of Arnold "The Governator" Schwarzenegger surely has its perks (she can ask him to say "I'll Be Back" anytime she wants, for starters.) But, when he's also a former Mr. Universe and mega-famous action star, it's likely body acceptance is a little more difficult, especially during the tumultuous teen years.

Her struggle for self-acceptance is why Schwarzenegger, 20, decided to write Rock What You've Got: Secrets to Loving Your Inner and Outer Beauty From Someone Who's Been There and Back, out Tuesday from Hyperion.

"I want to let girls know they are not alone with the changes and doubts about their body," Schwarzenegger told USA Today.

She cites her parents for giving her a good childhood.

"They were very protective of having us in the public eye when we were younger. We didn't go to Hollywood premieres. We practiced community service," she said.

However, Schwarzenegger's happy childhood didn't mean she was immune to self-confidence issues. Her fourth-grade year was when she started feeling fat and ugly, she said. It continued as she transitioned to middle school and attempted to stay as thin as one of her friends, though she denies that she suffered from an eating disorder.

Now, Schwarzenegger is a junior majoring in communications at the University of Southern California and maintains her positive body image with healthy eating, daily workout sessions and a close relationship to her mother, Maria Shriver, and father.

"I also have an amazing relationship with my dad. ... I talk to him about boys, about going out, about what I'm interested in, about business," she told USA Today.
