Kristin Cavallari [2] is living proof that hard work pays off. The "Laguna Beach [3]" star posted a new fitness record on her Instagram [4], deadlifting 185 pounds — for three reps, no less — without so much as breaking a sweat. "185lbs 💪🏻 new record for me," she wrote in her caption, tagging her personal trainer, Kevin Klug [5]. This accomplishment comes after Cavallari shared an Instagram story back in July doing the same trap-bar deadlift [6] with only 155 pounds. Now, with dedication, consistency, and a steadfast loyalty to strength training [7], she's already able to lift 30 pounds heavier — and she has the video to prove it.

Cavallari attributes a lot of this growth to her trainer, who she says always encourages her to push herself in new ways. "He kicks my ass," she told Us Weekly [8] in an interview from June. "He pushes me really hard. He has me actually lifting really heavy weight, the heaviest weight I've ever lifted in my entire life. I feel the best I ever have. I feel like I'm the strongest I've ever been."

Cavallari has shared about her journey on social media and talked about how impactful it's been to make fitness such a large part of her lifestyle. "I'm really proud of the progress I've made," she said in one carousel of photos [10] she posted to Instagram in late June. "I work out really hard and am dedicated to a healthy lifestyle and I think just because I'm a mom doesn't mean I can't be proud of my body and be comfortable in my skin."
