Along with being a “Dancing With the Stars” pro, Cheryl Burke has also been moonlighting as a blogger for People, and this week, she’s talking about partner Rob Kardashian’s weight loss since the “Dancing” workouts began. “He’s lost a lot of weight,” she says. “His whole physical appearance has changed. He’s using different muscles. He’s super sore all the time. I’m not sure if he’s changing his diet, but the cardio is really good. I think he lost most of the weight just rehearsing from the jive because it’s so fast-paced.” She says that he’s taken note of his changing physique, too — and that’s manifested in a little bit of vanity! “I can tell Rob is getting more comfortable with his body because he’s starting to wear tank tops to rehearsals. And you’ll see his arms out. In the beginning, you’d never see that. He looks at himself in the mirror. It’s really cute.”
