Isn't BMI broken? Why do people even use it?
BMI is pretty stuffty because it only takes weight and height into consideration.
When you then get those who train, they have large muscles, which weigh a considerable amount, their BMI picks them up as being overweight. Even if they were to have almost no body fat at all.
It's like me looking into a crowd of people and saying anyone who is wide is clearly obese. Regardless of their physical build.
