In an interview with Us Weekly published Tuesday, the Very Cavallari alum, 35, talked about the new confidence she feels in her body after developing a fitness regime that makes her feel "the best I ever have." "I've put on a lot of weight in the last few years, but in a good way," she told the publication, adding that she's not looking to go down a size anytime soon. "My goal is sort of, right now, just to maintain the muscle that I have. I'm not trying to lose weight," she continued. Kristin Cavallari Says The Hills: Next Gen Is a 'Slap in the Face' to Audrina Patridge In looking at some of her past pictures, the Uncommon Beauty founder said she was "shocked at how thin" she used to be. "I didn't realize it at the time, how thin I was. So I'm happy that I've put on weight," she said. Axelle/Bauer-Griffin/FilmMagic Without using a scale to track her weight, the Laguna Beach alum revealed she started building her muscle through workouts with a professional trainer. "I'm really petite. I have no hips. I'm just small. And so if I don't work out for like a week or two, I feel like all my muscle goes away," Cavallari said. "So it is about consistency for me."

"My work-life balance right now is at a perfect place and I'm really thankful for that." Kristin Cavallari Shares Her Favorite Mother's Day Gifts — Including One Item She 'Lives In' Cavallari shares three kids — sons Camden Jack, 9, and Jaxon Wyatt, 8, and daughter Saylor James, 6 — with ex-husband Jay Cutler. She announced her separation from Cutler, 39, in April 2020 after 10 years together. Earlier this month, the True Roots author was given relationship advice by her sons, who told her to "date somebody older." "I'm getting dating advice from my boys," Cavallari said in an Instagram Story. "Older, a lot older," Cavallari's son Jaxon said off-camera. "Much older?" Cavallari asked with a laugh as Jaxon went off-topic to introduce his two stuffed animal bulls. "That's riveting content," she deadpanned before getting back to the subject. "So why should I date somebody older?" As he struggled to explain, she asked, "Life experience?" "Young people are crazy," Jaxon replied, to which Camden then objected. "That's not true. I'm young and I'm not crazy. Mommy, am I crazy?" "You're wild and crazy in the best possible way," Cavallari assured him.
