I KNOW that athletes need to loosen up before their big moment, BUT, this Australian hurdler's warm-up video went viral because it's kind of ridiculous.Especially because she is smiling through the whole thing.  Normally they are frowning and focused.  Her name is Michelle Jenneke and she was competing in the World Junior Championships last weekend in Barcelona.  You may have the opportunity to see more of Michelle, they say it's likely that she'll make the Australian team for the 2016 Olympics in Brazil.
