Rob Kardashian

Rob Kardashian is determined to get into the “best shape ever”.

The 'Keeping Up with the Kardashians' star, who has been battling weight issues in recent years, has been praised by his personal trainer Gunnar Peterson for his commitment to working out and focusing on his health, despite leading a busy life.

Gunnar hit back at recent jibes directed towards Rob, 27, who appeared to miss his sister Kim Kardashian's wedding last month because of body confidence issues.

He told E! News: “He's such a good guy. Rob was a solid basketball player, a serious runner and he's a serious athlete. It's when life gets in the way, that's what makes it hard to get to the gym.

“Here's a guy fighting paparazzi getting in and out of the gym. This guy is fighting through human walls to get to the gym. A lot of people have blown off workouts with a lot less obstacles.

“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.”

The fitness expert claims Rob is extremely committed in the gym and is impressed by his determination, despite juggling his own sock business and pitching his own TV show.

Gunnar added: “If it was Rob on his own, he'd be in every day. He's pitching shows, he's on a show, he has his sock line and other business ventures.

“People forget. They think these people are walking around just being celebrities.” – Bang Showbiz
