What is your Body Mass Index (BMI)?

What is your optimal weight? A team of British researchers studied 7,700 men for 15 years to determine what constitutes the perfect balance.

SPECIAL NOTE: If you're under the age of 20, there is a different calculation to determine your correct Body Mass Index. Click Here to visit that calculator on the Centers for Disease Control (CDC) website.

Weight in pounds: lbs.
Height in feet and inches: Ft.  In.

This formula calculates your weight-to-height ratio, or height-to-weight. Either way, it is a measure of general fitness and health. The goal is to have the ratio, or Body Mass Index (BMI) equal about 22, although it should be noted that anything under 25 is considered healthy.
Here's a table showing the range:

Body Mass Index (BMI)
Underweight -   Less than 19  
Ideal - 19-25  
Overweight - 26-30  
Obese - 31-35  
Severely Obese - 36-40  
Morbidly Obese - 41-50  
Super Obese - 51+  

What those enviable British researchers found was that the lowest combined rate of heart disease, diabetes, strokes, and even death occurred in men whose BMI was between 20 and 23.9. Once your BMI gets higher than that, disease and death rates start rising about 10 percent per index point - or about every six to eight pounds for most people (depending on height).

"But, I'm a bodybuilder. Does this really apply to me?" Yes. You can get away with a higher BMI, but even for you, a BMI of over 30 isn't healthy.
