# BODY MASS INDEX

The Body Mass Index ( BMI ) is a guide to show what weight you should be for your height. It works on a score with a range from 20 – 25 and any score within this range is acceptable. A score or BMI of less than 20 indicates the person is underweight. A BMI of 25 – 30 indicates the person is overweight. A BMI of more than 30 indicates the starting of obesity, from slight obesity at the lower 30’s up to very obese at BMI’s of 40 plus.

The BMI score is only used as a rough guide as everyone has different body types and build sizes, however it should be made clear that if you have a small build then you should be looking at a BMI at the lower end of the ideal range of 20 – 25, for example 21. A BMI of 24/25 for this person could still mean slight excess weight. A BMI of 21 for a person with a large build could mean slightly underweight.

To calculate your BMI you need to divide your weight ( in kilograms ) by your height ( in metres ) – squared.

So:

weight (Kgs)

BMI  =  ———————–

height (metres) “Squared”

an example would be:

70 Kgs ( 11 stones )

BMI  =  ————————–

1.7 mtrs ( 5foot 7 inches) “Sq”

70

BMI  =  —————  =   24.22

2.89

BMI  =   24

The BMI is a rough guide for normal, average people so wrestlers or strength athletes or weight lifters will have a high BMI but a low fat percentage. The BMI score is inaccurate for these types.
