Kim Kardashian isn't using pregnancy as an excuse to let herself go. In fact, she's more motivated than ever to stay healthy. And she's got one heck of a secret weapon in her arsenal to help her do it: celebrity trainer Tracy Anderson.
Anderson -- whose other clients include Gwyneth Paltrow, Jennifer Lopez, Bethenny Frankel, and mom-to-be Shiri Appleby -- is working with the E! reality star to develop a fitness routine that works for both her and her baby.
"She's been doing amazing," Anderson gushes to Us Weekly of the three-months-pregnant 32-year-old, who's expecting her first child with boyfriend Kanye West later this year. "She's doing it with caution and she's listening to her body; she's not overdoing anything. [She's] such a great example -- I'm so proud of her."
The admiration is mutual. Anderson not only helped Kardashian's sister Kourtney lose 44 pounds in six months after the birth of daughter Penelope; she also specializes in helping women stay active through each stage of their pregnancy and beyond. She even has a new series of DVDs, the Pregnancy Project, that feature different workouts for each month leading up to labor.
"It's about staying connected, it's about circulation," she explains to Us of her maternity fitness philosophy. "Every month is really different."
Every woman is really different, too -- so Anderson is customizing Kardashian's routine just for her specific needs. "We take it one day at a time," she explains. "One of the things that I love is that she doesn't want to go crazy. She's not interested in being like, 'I want to look hot during my pregnancy' or anything like that. Just like, 'I want to be healthy, I want to take care of myself and the baby...' She knows I'll get her back better than ever after [the birth]."
The fitness guru tells Us she's been very impressed with Kardashian's work ethic -- as well as with her attitude toward motherhood. "I think she's going to be a really natural mom...You can see that she has a real love for and a real connection to babies. I think right now she seems like a very in-tune, very together pregnant mom that has that first baby glow," she explains. "She just seems to be totally on the right track, really healthy of mind and spirit, and totally ready to do this in the best way."
"She seems to be really at home and really at peace," Anderson adds. "I think this is going to be a really big year for her."
