Celebrities Who Got Fit With P90X

Oscar-winning actress Marlee Matlin, known for her roles in "Children of a Lesser God" and "The West Wing," uses P90X. The only actress with a hearing impairment to win the Academy Award for Best Actress, which she won for the 1986 film, has made YouTube videos promoting the workout DVDs and tweeted about them last year: "Did you know that @p90x videos are closed captioned?"
