Michelle Jenneke, who is set to represent Australia in the 100-meter hurdles, posted a series of photos to Instagram from training in Florida, showing off her abs and Olympics uniform.
The internet sensation rose to fame in 2012 when a video of her pre-race warm-up dance went viral on YouTube.
And now she has found herself gaining popularity again thanks to her revealing selfies.
Sharing a snap with her 200,000 followers on Instagram, Michelle wrote: “First week of training in Florida done and dusted and only 3 more days till I leave for Rio!!”
The brunette beauty reclines on a towel on the grass in the snap, her ample chest on full display.
The shot also gives her fans a fantastic view of her perfect abs.
Michelle wears a green two piece by Adidas in the photo.
Her followers love the racy image and it has received over 20 thousand likes.
They had plenty of words of encouragement for her, with one commenting: “Good luck, I’ll be watching! Go for Gold!”
Another was so impressed he proposed marriage, writing: “Marry Me”
Michelle had shared a similar photo a few days before and captioned it: “Cooling off in the shade today after a hot session in Florida.
“Also picked up my Aussie uniform today!”
Jenneke and the rest of the Australian athletics squad will fly from Florida to Rio on Wednesday.
She will compete in her first heat in the 100m hurdles in a week’s time on Wednesday, 17 August.
With a personal best of 12.82 in the 100m event, Jenneke presents an outside chance to scoop a medal at Rio.
Michelle shot to fame in 2014 when her pre-race dance routine caught the eye of viewers worldwide.
In the short clip, Michelle is standing with other hurdlers at the start line, but while the others are standing still, trying to calm their nerves, the Aussie begins swinging her hips.
