This chart works much better for me.. when I first got married, I was 180 lbs. Top of the weight chart for my large frame size according to WHO. I was skin and bones and my ribcage stuck out. At 200 to 210 lbs I was at me best weight and fitness...I am a little over 230 right now and according to the WHO charts I am morbidly obese. This chart makes more sense. I'm over weight, but not obese.....now, you guys are motivating me...my wife isn't able to exercise as much as I need to, so starting today I'm going to do more and try and get back under 220......wish me luck, drifters...did I just use that word?
