Rob Kardashian is putting in work at the gym.
The E! star's trainer Gunnar Peterson exclusively talks to E! News about the 27-year-old's workout routine and how he's working really hard to get back into shape.
"He's such a good guy," Peterson tells us. "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."
But Gunnar and Rob try to hit the gym whenever they can. It just gets challenging at times with Kardashian's busy schedule. "If it was Rob on his own, he'd be in every day," but Rob has a lot of commitments, "He's pitching shows, he's on a show, he has his sock line and other business ventures."
