Mitt Romney and Evander Holyfield released a promotional video ahead of their charity boxing match, scheduled for Friday.
Romney, the 2012 Republican presidential nominee, and Holyfield, the former world champion boxer, will enter the ring in support of Charity Vision, a Utah-based medical nonprofit that Romney and his family support.
In the video, Romney and Holyfield warm up with some verbal punches.
"Does he even work out?" Holyfield says.
"You may think this is a joke, but I'm taking this very seriously," Romney responds, while lifting barbells.
Watch the video above.
