50 Cent has rapped about getting rich. Now he's focusing on getting fit.

The hip-hop star is putting out a fitness book that's set to be published in January 2013 by Avery Books. Titled "Formula 50: A 6-Week Total Body Transformation Plan," the book will tout metabolic resistance training as the key to getting in shape. It will also include a nutrition guide.

The buff rapper says he wants to help people "make positive changes and take charge of their overall health."

"Formula 50" will be the latest credit for 50 Cent as an author. He recently released the teen novel "Playground" and also wrote "Pieces to Weight, The 50th Law."

The rapper's latest book will be co-written by Jeff O'Connell, editor-in-chief of Bodybuilding.com.

50 Cent hasn't forgotten about his music: he recently released his latest mixtape, "The Big 10."
