Anyway they did a whole BMI thing and they took 3 guys who are considerd obese by the BMI chart and had them go up against someone who is considered normal on BMI chart, running, hurdles etc. the guy that was normal was damn near worthless. He was beaten by the "obese" people I think 90% of the tests.
The BMI is virtually worthless in all directions but the only time it is even remotely accurate is if it is used to measure people that have never had any exposure to weight training or physical activity that could possibly promote muscle growth.
The fact that the BMI is still used by anyone is beyond me. It is about as accurate as someone trying to measure water temperature by looking at it.
