First Lady of the United States, Michelle Obama, is known for her fitness and big "guns" among other things.

So when Ellen DeGeneres asked the First Lady to do some push-ups on her show today, she did not hesitate dropping to the floor and doing 25. Although, she said could have done more.

"I just stopped," she said.

"I thought it wouldn't be good to show up the First Lady, so I stopped," DeGeneres said after Obama beat her. "Because I thought, this looks bad that I'm going to beat her. I'm 54, and you're 48."
