I know that I would be considered overweight even though I'm prolly in better shape than many other people out there, but I agree with the BMI scale if it measured how much a person eats because I eat a truckload of food everyday, more so than the "average" person
besides, I'm sure those of us on the forum who work towards getting into better physical condition, injuries or not, have a motivational aspect. I mean, if my whole goal was to be better than the average Joe, I would accomplish that goal within a few weeks, then slack off because there's no more goal. I know that I continually compare myself to the people in better condition than I am so that I always feel like I need to get better. If I compare myself to Mr. Smith who just picked up a barbell for the first time in his life, I would get either lazy or stagnant on my lifts.
