Obama made it to 25 while DeGeneres stopped at 20 push-ups during the contest, although both women joked that they stopped before they had to. Later, DeGeneres jokingly questioned the first lady’s form. They were both doing military-style push-ups, but the first lady lowered the intensity by never dipping below her elbows.

A tweet exchange between the two women, where tweets from the first lady are marked “-mo” to indicate she sent them personally, indicates Michelle ObamaMichelle LeVaughn Robinson ObamaGeorge H.W.

Questions about Michelle Obama’s form made it all the way to President Obama, who joked about the contest in June at a fundraiser with DeGeneres.

“I want to thank my wonderful friend who accepts a little bit of teasing about Michelle beating her in push-ups -- but I think she claims Michelle didn’t go all the way down,” he said. “I just want to set the record straight: Michelle outdoes me in push-ups as well.”

The first lady has appeared on DeGeneres's show several times, and since earlier this month she revealed she prefers sit-ups to push-ups when she gets a choice, her offer of a rematch just might be coming soon to day time TV.
