First lady Michelle Obama wants to know -- how do you move?
The first lady announced a new component of her "Let's Move" initiative during her appearance Thursday on "The Tonight Show with Jimmy Fallon."
"What we ask people to do is show us how you're moving," she said. "I want to see how people around the country are moving and changing the standards for health for our kids because people are doing some amazing things."
Obama's "Let's Move" campaign against childhood obesity starts its fourth year this week.
The first lady encouraged people to use social media to spread the word and provided some incentive for people to get started.
"And the fun thing is, is that if we get enough of a response, we will have a little surprise. The president and maybe the vice president will show us how they move," said Obama.
In case the two need any pointers there is the video Obama and Fallon collaborated on during her past appearance in 2013, "Evolution Of Mom Dancing."
Starting the show with a sketch where Fallon and fellow guest, Will Farrell, were dressed as pre-teen girls hosting a fictional show called "Ew," the first lady joined them sharing tips for a healthier lifestyle.
"I do try to exercise every day," Obama said. "Exercise is not EW. You just have to find an activity that's right for you. For example, I like to dance, play tennis, even do some push-ups."
Fallon's character Sara may not have known that about the first lady but Fallon experienced it firsthand in 2012 when he and Obama competed at the White House in a calisthenics challenge, where the two went head to head in tug of war, hula hooping, and, yes, push-ups.
Obama's guest appearance is part of Fallon's debut week as the new host of "The Tonight Show."
