BMI

A population measure, shown with the caveat it needs. It is a good description of a thousand people and a poor description of one.

Your BMI

Example

23.7

That falls in the healthy weight band.

0 to 18.4Underweight
18.5 to 24.9Healthy weight
25 to 29.9Overweight
30 and overObese

1.78 × 1.78 = 3.1684
75.0 ÷ 3.1684 = 23.7

Nothing in that equation knows what the weight is made of. Muscle is denser than fat, so a lifter can land in the overweight band on a body nobody would describe that way. For health risk, your waist measured against your height is the better number.
