DeSanti, who rappelled from helicopters to treat wounded soldiers during the Vietnam War, showed off her muscles on camera while she performed 10 full push-ups without stopping, all while dressed in her uniform, FOX 10 reported.

When she was done, another agent helped the octogenarian to her feet.

DeSanti and the TSA agent were all smiles as they posed for photos after the calisthenics match.
