Bounce, wobble, stretch and eat your way to a healthy BMI

To work out your BMI (Body Mass Index) first measure your height: the best way is to stand with your back to a wall, get a friend to mark the height with a pencil. Use a ruler or straight edge to get it accurate so you measure from the top part of your head. Next weigh yourself, set the scales to metric

Then use the formula

BMI = weight (kg)/ (height (m) x height (m))

To convert height to metric you need to know that 1 inch is 0.0254 metres
To convert weight to metric 1lb is 0.4545 kg

Or automatically calculate your BMI on the NHS Choices website

Underweight: BMI is 18.5 and below
Normal weight: BMI range is from 18.5 to 24.9,
Overweight: BMI range is 25 to 29.9
A BMI of 30 or greater indicates obesity

If you are a wee bit over perhaps you need to get more active, this is what I do: bounce, wobble and stretch – see my article on keeping fit and think about your eating and drinking habits

If you are a highly trained Olympic athlete don’t waste your time calculating your BMI, it will probably be meaningless! For us lesser mortals it is quite a useful guideline, easy and quick to measure and calculate.
