The First Lady will make a big reality show debut on ABC’s “Extreme Makeover: Home Edition” as part of an outreach program to military veterans.

Mrs. Obama hit the road for Fayetteville, N.C. to help Ty Pennington and his crew build a design project for female veterans. She also pitched in to help with some gardening.

“This particular show is especially moving because it features Barbara Marshall, a Navy veteran, who despite her own struggles opened her home to serve homeless female veterans in her community,” Obama tells PEOPLE. “She’s an amazing example of the strength, values and service of America’s veterans.”
