There is a lot of attention surrounding Rob Kardashian and his extra pounds, and now the "Keeping up with the Kardashians" star has an advocate on his side - his trainer.

Gunnar Peterson told press that he is working hard with the reality brother in an effort to get Rob back to his healthy weight.

During an interview with E! News, Gunnar said, "Rob is such a solid guy, when he gets in here. I don't care if he weighs 50, 100 or 200 pounds. He works like an athlete. He never tries to beg out of a set. He never tries to hop off the cardio a minute or two before. He goes the distance every time."

In addition, Peterson said Rob is "a solid basketball player," "a serious runner," and a "serious athlete," adding that the pair works out as often as possible. However, he added, "if it was Rob on his own, he'd be in every day."

"There's no doubt in my mind. With 26 years of training experience of doing this, I can tell you without hesitation that Rob Kardashian will get back to his best shape ever. There's not one doubt in my mind."
