Michelle Jenneke in sexy new workout video

Michelle Jenneke, the Aussie hurdler who shot to fame when her warm-up routine went viral a few years ago, has taken her sexy image to new heights.

If you've heard of Michelle, chances are it's not for her athletic prowess.

She won the silver medal in the 100 meter hurdles at the 2010 Summer Youth Olympics and competed for Australia at the 2014 Commonwealth Games.

But sometimes her accomplishments on the track are overshadowed by her looks, and the above video will certainly not help with that.

In a steamy new video for WorldstarHipHop, she trains, hangs out in a bikini, does her world-famous warm-up and then jumps some hurdles, all while looking fantastic.

The video highlights Michelle's work-out routine, but takes no shame in focusing on her best assets.

Check it out above.
