The milk crate challenge includes walking across a tall stack of milk crates.

“They’re all landing like on their chest and abdomen, which is very concerning,” said Dr. Crystal Arthur in the article. “If you dislocate your shoulder at 22, you’re probably going to have issues when you’re 65.”

YouTubers JC and ANT led the way in bringing the viral challenge home to Detroit, according to the article, with people filming the challenge on the east side.

“As soon as we posted, 200 shares, quick, like everybody wanted to do it,” JC said in the story. “We are in Detroit, everybody tough out here, you feel me? It’s all fun.”
