“He made it his goal to get well before graduation and he stuck to it,” a source told the website last year.

“He started exercising and making better food choices. He was in school for a few years and lived like a typical college student for a few years, but he’s now growing up and ready to take better care of himself.”

The insider said Christopher didn’t lose the weight on a “craze diet or crash diet.” Instead, he’s lost weight the old-fashioned way by cutting out junk food and exercising.

His efforts to live healthier have even impressed his family.

Last year, when Christopher celebrated his 24th birthday, both his father Arnold and brother Patrick praised him for his training regimen.

“Between your boxing classes, your weightlifting classes, your stretching classes, your cycling classes and so on, I can’t even keep up with you!” his famous bodybuilder father raved on Instagram.

Patrick wrote: ‘Proud of you. New job. Crush in the gym. Whole new person. I can’t wait to see what this year brings.’
