Here's how to look like 'Hercules.'
Dwayne "The Rock" Johnson may be one of the most ripped actors in Hollywood, but when you're playing the demi-god Hercules, you still gotta go that extra mile.
How did the 42-year-old actor get in the Herculean shape needed to fight man-eating lions, giant bores and armies of enemies? Apparently, he watched fitness videos made by the old workout self-help duo The Fungo Brothers!
In actuality, the Fungo Brothers were just part of a great sketch on The Tonight Show starring Jimmy Fallon, in which Jimmy and Dwayne donned some ridiculous wigs and showed us all how to use a "thigh cruncher" and a shake-weight device they called a "Jack weight." WATCH.
