Jamie Foxx revealed in a recent interview what he's been doing to prepare for his role as Mike Tyson in an upcoming biopic!
Foxx says he has a daily workout regimen of 60 pull ups, 60 dips, 100 push ups ... "It's changing the body. Top half."
As for lower body? There's a different plan for that.
"I ain't got no legs, I ain't got no calf muscles so we're gonna have to get some prosthetics for that."
Foxx says he'll be 216 pounds when shooting begins (he starts as young Mike) -- and then to play Old Mike, he'll "balloon to 225, 230 which will look like 250 on screen."
