 ‘He made it his goal to get healthy for graduation and he stuck to it,’ a source told the website last year.

‘He started working out and making better food choices. He was away at school living like a typical college kid for a few years, but he’s growing up now and ready to take better care of himself.’

The insider said that Christopher didn’t drop the weight through a ‘fad diet or crash diet.’ Rather, he has been losing weight the old fashion way by cutting junk food and working out.

His efforts to live a healthier lifestyle have even impressed his family.

Last year, when Christopher celebrated his 24th birthday, both his father Arnold and brother Patrick  commended him on his exercise regimen.

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

Patrick wrote, ‘Proud of you. New job. Crushing in the gym. Whole new person. Can’t wait to see what this year brings.’
