I've had this converstaion with my doc: does BMI take into account frame shape? i'm 6'2", and 245. i ran a marathon 2 yrs ago, and never weighed less than 230. (maybe a lil less at the end from water loss...) my suitcoats are size 48 long. i don't think i'd look very healthy if i weighed 200 or less. anyway, running does hurt, but riding only breaks the bikes!
