According to Us Weekly, Chyna has enlisted her personal trainer Chris Jinna, to help Rob come up with a diet and workout plan to get back in shape.

"[She came to me] recently, maybe a week ago," he told the publication. "She just asked some type of tips for Rob, to get him a meal plan. So I created a plan for them and sent it over."

"They just want to basically get in shape," the trainer added. "Just have a healthier life, live a healthier lifestyle."

Meanwhile, a source close to the family told ET this week that Chyna's relationship with Rob has caused some worry given his "fragile" state, coupled with her complicated past with the Kardashians. The 27-year-old model is Kim Kardashian's former BFF, and has a 3-year-old child with Tyga, who is now romantically linked to Kylie Jenner.

"The problem in this situation is no one wants to push too hard on Rob because of his fragile state," the source said, adding that Rob hasn't gotten his weight under control, and is still over 200 pounds. "Yes, Kylie feels betrayed, but she also doesn't see the need to publicly taunt him. If this relationship is good for Rob, even if it's temporary, then Kylie is not going to push it. She'll get over it."
