Lederer, 18, said 'Zaching' began when he flexed his muscles coming out of surgery, and his father took a picture. "I wanted to make it very clear that 'Here I am, strong as ever,' " Lederer said.
He said he is grateful for the phenomenon of people around the country striking similar poses in support -- "Zaching."
“The coolest ones in my mind are the ones of the kids in the hospital,” he said.
