Wrestler-turned-actor Dwayne "The Rock" Johnson is one of the biggest, most muscle-bound dudes in Hollywood, but the hulking man appears to have transformed himself into a true colossus for his role as Hercules in Brett Ratner's upcoming "Hercules: The Thracian Wars."

Late last month The Rock took to Twitter to share his insane 22-week diet for the film, which has him consuming about three pounds of meat and fish a day, as well as 14 egg whites. He also hits the gym every morning -- and not for a breezy spin on the elliptical.

Earlier this week he tweeted behind-the-scenes proof that the extreme diet and workout regimen -- the epitome of a Herculean effort -- is doing its job, building the actor into a mortal version of the Greek demigod.

Based on a comic book by Steve Moore, "Hercules: The Thracian Wars" will storm into theaters July 25, 2014.
