At physical they always note my bmi. it is always over 30 plus. i argue with doc why he puts it in my chart. i am under 10% body fat bodybuilder ?

Don't think about it: Doctors record your normal weight, even when it is normal. We record normal heights, normal blood pressures, and lots of normal findings. Recording a normal bmi is part of that (and the government wants it recorded as preventive care, due to other's - not yours - weight problems). Medical data is going electronic, so bmi is now calculated from height and weight, regardless of what the doctor does.
