Estimated BMI: 30.8
This former bodybuilder and Terminator star is the poster child for physical fitness. But surprise! He's "obese"—at least according to his BMI. He stands tall at 6'2" and our experts say Schwarzenegger probably weighs in at about 240 lbs., which would give him a super-high BMI of 30.8.
Schwarzenegger shouldn't sign up for a weight-loss program just yet. All that muscle mass can yield a misleading BMI. "I'm hoping that we'll find another easy calculation to replace BMI soon," says Largeman-Roth. "After all, it was developed in the 1800s."
