Contestant David Cook told Fox that "nobody can say they've worked harder for this." Cook even works out before performing -- he stretches his hamstrings as a ritual before every show. Perhaps he should keep doing what he's doing! Many consider the 25-year-old Missouri native a favorite to win this year's competition, including last year's winner Jordin Sparks, according to US Weekly. However, Cook had a health scare Tuesday night when he was admitted to the hospital after he felt heart palpitations. He's returned to the "American Idol" apartments and is "doing fine," according to People. (Frank Micelotta / FOX)
