Poll: what is your BMI (body mass index )?

Yep ... when I'm training, I get thinner and heavier as I replace fat with muscle. How out of shape can an ultra-marathon wannabe be?

Yep, BMI is horrible especially if you have any muscle on you. My BMI is 27 which is in the overweight range which I definitely am not. Edit: Really what you should be concerned with if you are trying to judge fitness level is body fat %.

I find it useful for metric for comparison. I can't compare my weight to yours as we have different body types, height etc. . However, if your BMI is in the 18.5 - 24.9 range and mine is 26, it would be a fair to say that you are in better shape than me.
