Body Mass Index (BMI)

The ideal body weight for a runner is said to be 45.36 kg (100 lbs) for the first.1.52 m (5 ft) of your height, and a further 2.25 kg (5lb) for every 2.5 cm (1 in) above 1.52 m (5 ft).

If you happen to be more than 3 kg (7 lbs) over the 'ideal' weight, it is recommended that you consider walking as an alternative to running, at least for a couple of weeks (assuming you are able to get in shape).

Measuring your Body Mass index (BMI) to asses your body weight status.
a)  Measure your height in metres and your weight in kilograms
b)  Divide your weight by your height squared (W/H^2)

OK, here goes nothing again.

Writer's height in metres = 1.5494
Writer's weight in kilograms = 54

Height squared = 2.4006

Weight / Height ^2 = 54 / 2.4006
Writer's BMI          = 22.494

Now for the ideal body weight for a slightly vertically challenged writer:

Base height :  1.52 m                 Base weight :  45.36 kg
Extra height :  2.94 cm               Additional weight :  (2.94 * 2.25 / 2.5) =  2.646 kg
HEIGHT = 1.5494                    WEIGHT should be = 48.006

Oh dear, there you have it folks, I've known it all along ... I need to lose some weight.

(Arrgghh ... I need to lose a LOT of weight.  I am 15 lbs over my ideal weight.)

Now that I've done the math, the numbers cannot be disputed.
