Nelly’s headed to the place where once thiriving entertainment careers go to die: Straight-to-DVD! In what may be the worst thing to happen to the “Country Grammar” hitmaker’s career since the evolution of Kat Stacks, Nelly is helping his fans work their waistlines down to ‘26″ with the release of a new fitness DVD, entitled Celebrity Sweat.

The heavily-muscled star — who regularly plays basketball, baseball and football — plans to introduce an exercise regime aimed at helping others achieve the buff and chiseled physique he’s become known for. 

“People think I just woke up all of a sudden and I was this big, but they haven’t been paying attention… If you look at the pictures from ‘04 to now, you can see the change. You can see me go from 160 to 170, 170 to 175, 175 to 180 to 190 (pounds). You put in all this hard work, and people want to discredit you. But you can transform your body in six to eight months. In two years, you can create a whole new person.” arrives next month.
