Rob did a great job last week on Dancing with the Stars. He was really feeling the dance. I think it gave him some confidence with the judges. And he was really happy, especially when Carrie Ann told him he was better than his sister.
It’s just nice to hear positive feedback, especially for Rob. He does have his insecurities and he does have low self-confidence. I think it really pushed him to do even better this week.
Rob’s also become more and more competitive. No one wants to get a bad score on Monday night, and the only way to avoid that is to really work hard. He’s taken it seriously from the beginning, but I think now he wants to make sure he improves every week.
He’s lost a lot of weight. 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.
