What's your BMI?

BMI is a calculation of your body fat based on your height and weight and can be a good indication of where you stand in terms of health brackets. Hydrostatic weighing is the most accurate way to test your body mass index, but I’m assuming most of you reading this don't have a big water tank available to weigh yourself in right now!
Below is a generalised formula for BMI.
Of course it is not totally accurate and does not take into account excessive amounts of muscle weight for example, so wont be good for someone very muscley with low fat, but for the most people will give you a good idea to what group you fall into.


BMI Classification
<18.5                  Underweight
18.6 - 24.9           Healthy
25.0  -29.9           Overweight
