You think conquering the world is easy? Gotta have powerful bones to do it, sister. Sitting on the sidelines is no fun — in sports AND in real life. Keep those bones in shape and keep yourself in the game. Girls with powerful bones are up to any challenge. Powerful bones are like piggy banks. The more you put into them today, the better off you will be in the future. Girls who take care of their bones take care of their minds, too. There's nothing sassier than a smart, powerful girl!
