Celebrities Who Got Fit With P90X

Ashton Kutcher's six-pack may be the result of a P90X workout routine. During a press conference last year, the "Two and a Half Men" star said he bought workout DVDs from an infomercial but didn't outright name P90X. But Kutcher, 33, has tweeted about using the P90X program before. One 2009 tweet said, "I can't get my p90x dvd to play on my mac pro." His wife Demi Moore also spilled the beans.
