On Tuesday's Tonight Show, host Jimmy Fallon got Dwayne "The Rock" Johnson to star in a spoof workout video where the two play the Fungo Brothers. They first start out with the thigh cruncher, though Fallon, a.k.a. Jeff Fungo, finds the workout a bit hard.
"You'll know it's working when you feel the burn between your legs," Johnson, a.k.a. Tad Fungo, insists.
"And remember, you gotta hustle for the muscle!" the men say in unison.
