BMI DOES work for the majority of people, we're just such a fat nation we say "That's rediculous it can't work! I'm healthy even if my BMI is 30!". The only place the MBI doesn't work is folks who have very low fat reserves but very large muscles (aka ripped). If you don't have a 6 pack, you still have too much fat to be claiming muscle. I've put on 22 lbs of muscle before and still been at 25.2 BMI. If you think BMI is crap, then you need to lose weight.
