Aussie hurdler Michelle Jenneke's unintentionally sexy pre-race routine goes viral

Michelle Jenneke's athletic warm-up has got clammy-palmed internet users all excited. 

The 19 year-old brunette hurdler for from the Australian team at the World Junior Championships did some enthusiastic pre-race bounces and hip shakes ahead of her 100 metre hurdle race in Barcelona.

The action was put into sexy slow-mo by Vimeo uploader Losse Veter.

Unfortunately Jenneke hasn't qualified for the Olympics so her smiling face won't be seen again at London 2012. Yes, sorry about that...
