Kristin Cavallari’s Pilates instructor, Angeline Mitchell, is revealing the secrets to Cavallari’s impressive post-baby body, saying “she looks amazing.”

How Kristin Cavallari Got Her Body Back After Baby

Cavallari gave birth to her second son, Jaxon Wyatt, on May 7, and six months later Cavallari looks better than ever. According to Mitchell, Pilates enabled Cavallari to have an easier time getting her body to bounce back after baby the second time around.

“The reason why she wanted to actually start doing Pilates was because she had heard that she could continue to do it throughout her pregnancy, and then also to get her body back after she has a baby,” Mitchell said in an interview with People.

Mitchell revealed that she works with Cavallari two times a week, focusing on her core, and that the designer and Fabulist host supplements her Pilates sessions with one private training session a week.

But, it isn’t all about working out. The mother of two is also very mindful of her diet. “She’s very conscious about what she puts in her body, and she’s super committed [to her workouts]…. She’s very consistent and she’s very motivated and driven,” Mitchell said.

Cavallari herself told E! News in August about her obsession with her diet, saying, “I’m a freak about what I put in my mouth. I’m constantly reading labels and I don’t eat any toxic chemicals, so I think that plays a huge role.”

In July, Cavallari revealed that she was already close to returning to her pre-baby weight, admitting that she was able to get in half-hour workouts at home when Jaxon was about three weeks old, and soon after she picked up Pilates again.
