and the police....which is a buggar cos they use the fat test too where they pinch your fat bits. When i left the accedemy I weighed 54kgs. I am 165cm tall. I had less than 20cm of fat on the pinch test. I was grossly underweight. My BMI was under 21. However - to their credit I had to put on 2 kgs to get to the 54kg before they would let me attest. 12 months later I weighed 60kg and got over 100cm on the fat test.....it can't have been 5kg of pure fat.
Very flawed.

I also was there with a guy who's BMI was 44 - they weren't going to let him attest. He was however a state sprinter and was a weightlifter - he could leg press a tonne (1000kg)
