Audrina keeps fit with Pilates, boxing classes, swimming and hikes.
Speaking with a daily, Audrina revealed the secret behind her fabulous body, “When I`m sitting in front of the TV, I lift five-pound weights or do squats. And I wear heels when I vacuum because it works my calves and my butt. I feel more toned and more defined for sure. I`m really, really defining my muscles and toning up.”
