This is obvious to anybody that sees black men in real life.
The crazy thing is that chart is thrown off by BMI, which puts even super in shape dudes in the overweight category.
I'm 6'7 250lbs and considered overweight by CDC standards when people think I'm a professional athlete when they see me in real life.
Black men are easily the most in shape race of men and it's not close. Only reason Asians are lower than us is because they naturally have slender builds, but they're frail.
