The Raismans.
Twenty-two-year-old Olympic gymnast Aly Raisman is probably nervous before going into a competition, but likely not as nervous as her parents are when they watch her compete. The Raismans — who were incredibly animated in the stands at the 2012 London Games — brought their A-game to Rio while watching their daughter on the uneven bars. Their routine includes tightly gripping each other, covering their eyes with their hands, and quietly muttering words of encouragement: a perfect 10 all around.
