White House chef Andre Rush flexes his viral biceps for veterans this Fourth of July

White House special events chef and Army veteran Andre Rush knows how to man the grill and flex while he's at it.

Rush's enormous 24-inch biceps went viral in June when reporters noticed the buff chef preparing a meal at the White House for Trump's Ramadan event and tweeted out the photos. Turns out he's a bit of a renaissance man and was often regarded as the Army's strongest chef by lifting over 700 lbs, as well as being a master ice carver, pastry chef, chocolatier, and an array of other specialties.

Rush, who served over 23 years in the United States Army, is putting his biceps towards a cause that's close to his heart.

This Fourth of July, he teamed up with the USO's #Flex4Forces campaign, which invites Americans to show support for service members by flexing their biceps on social media, and asks others to do the same and make a donation.

Tens of thousands of Americans have participated so far to show their support for service members, including celebrities like Dwayne "The Rock" Johnson, Jessica Biel, Chris Pratt, Elizabeth Banks, Tim McGraw, Zosia Mammet and many more.

Rush flexed for "GMA" and nominated Arnold Schwarzenegger to take part in the challenge next. He also shared some of his favorite grilled dishes that you can try all summer long. Get the recipes below.
