In a video posted to her Instagram page, the 20-year-old model looks fierce while emerged in a boxing class at her gym.

Wearing a rather uncomfortable-looking bomber jacket, the stunner is taking no prisoners with her sharp jabs and upper cuts, clearly relishes in the final few days of workouts ahead of the show.

Earlier this year, she told Vogue magazine: "Boxing's been great for me, it's like my new sport and it's something that I can get better at."

Aussie model Bridget Malcolm yesterday told Sunrise about her vigorous workout regime, claiming she goes to the gym for two to three hours a day and also meditates.

“For me it was a matter of getting into shape, both physically and mentally," she said.

"I had to work on what I was eating about three months before and then really step up the workouts about a month before.

"So for me that meant twice a day workouts. So doing pilates and something intense in the evening and then also doing a daily meditation routine."
