Arnold Schwarzenegger’s son Christopher just dropped jaws with his 30lb weight loss during a rare family day out in Cape Cod! Katherine shared pics of the fam looking windswept and happy, but everyone’s talking about Christopher’s flexed biceps and healthy glow. He opened up about how his Aussie adventure inspired him to get fit after struggling for years. Proof that even celeb kids have to work for it—and the results are worth it! #Fitness #Schwarzenegger #FamilyGoals
