"I started playing rugby my senior year of high school. I don’t love my body all the time but I’ve grown to really appreciate it. I get very mad at myself when I make mistakes. I’m self-conscious that my personality may be too much for some people. Tik tok is a way I can escape and not stress about my upcoming games," she said in the video.

Earlier in the week, Maher posted several hilarious videos about her interactions with other athletes in the Olympic Village.
