As an aside, long-term (which is where we really care about "healthy" anyway), you would probably expect body builders to be healthier than some classes of athletes, with various circumstances obviously influencing that.
Professional sports are notoriously rough on the body (and mind) long-term. It's not a secret that athletes in certain sports (e.g. american football, boxing) often have debilitating health issues in their later years stemming from their career. I'd say Arnold is doing a hell of a lot better health-wise than Muhammad Ali, for example.
