Move over, Arnold Schwarzenegger, there's some new muscle in town.
Vice President Joe Biden put his weight behind Michelle Obama's Let's Move campaign Friday via a Vine video in which Biden performs bicep curls. "I do a million of these a day," the vice president says in the video, "so just give me five."
Obama's latest health challenge -- #GimmeFive -- celebrates the fifth anniversary of Let's Move, an initiative the first lady launched in 2010 to combat childhood obesity.
Earlier Friday, the first lady appeared on NBC's "The Ellen DeGeneres Show" to demonstrate a choreographed routine she plans to perform at the 137th White House Easter Egg Roll on April 6. The White House expects more than 35,000 people will gather on the South Lawn for this year's edition of the annual event.
Singers Beyoncé and Nick Jonas, as well as TV personality Ryan Seacrest and NBA player Dwyane Wade, have already participated in Obama's #GimmeFive challenge.
