Jake Pavelka isn't the only reality star not wowed by Mike "The Situation" Sorrentino's six-pack.

In an exclusive video on UsMagazine.com, trainer Jackie Warner (star of Bravo's Thintervention) says, "I don't like The Situation's abs!" (see video, above). "Everybody says Mike's got great abs, I don't like how he's formed. I like a beautiful six- or eight-pack, and I like it to pop out on a guy."

Who has fab abs? Twilight hunk Kellan Lutz.

Says Warner, "Kellan has the best abs in Hollywood!"
