Everyone on FPH already knows this but for the fatty lurkers reading on at home, 200lbs lean is fucking massive. I am 6'2" and 205lbs lean. I am enormous. My biceps are thicker than most peoples' necks. It is VERY unusual for me to meet anybody bigger than me. I have a BMI of 26. (barely overweight). For someone 5'  (over a foot shorter than me) to be 200lbs and not be fat they would be bigger and more muscular than Arnold Schwarzenegger, by a significant degree. A women who was 200lbs of muscle at 5' would, proportionately, be as big as the men on the Mr Olympia stage, the most muscular men on earth. It would certainly not be a tiny little softball player. BMI isn't broken, BMI works. You're much more likely to be in the 18-25 BMI range still be fat than you are to be 25+ and lean. If you're 25+ BMI and you aren't an ELITE (not casual) athlete, then you're fat.
