If you're the "I’m the type to swallow my blood ‘fore I swallow my pride" type of athlete, we've got your new favorite read.

50 Cent of lines like the above and "If I can't do it, homie, it can't be done," is taking his tough mantras into the world of fitness. Welcome Curtis Jackson's first instructional book, co-written by the editor-in-chief of BodyBuilding, Jeff O'Connell.

Jackson stopped by the Today Show yesterday morning to talk his workout inspiration and background and reveal his book, Formula 50: A 6-Week Total Body Transformation Plan. He explains the idea behind the book's two-part program: one for novices, and one for advanced athletes. The six-week program mixes workout instructions with tips on maintaining a healthy diet. It puts an emphasis on metabolic resistance training (MRT), which 50 says has been one of the key factors in maintaining his physique.

Head over to This Is 50 for the Street King's latest creation.
