Michelle Obama is famous for her toned arms and she showed talk show host Ellen DeGeneres exactly how she got them this week.
The US First Lady was appearing on The Ellen DeGeneres Show to promote her fitness campaign Let's Move when she was challenged to practice what she preaches.
Michelle promptly dropped to the floor and did 25 push-ups in front of the cheering studio audience.
But while Michelle's effort was impressive, Karl Stefanovic's TV push-ups on The TODAY Show this morning were even more remarkable.
Karl asked co-host Lisa Wilkinson if she was willing to try to beat Michelle's effort before getting down on the studio floor to do it himself.
Karl put on an extraordinary display, doing several regular push-ups before showing off with some more exotic displays of strength.
Things got weirder from there, with Karl sexing it up for the cameras like an adult entertainer.
Check out the video above to see Michelle's TV workout and Karl's exotic dancing session.
