KInd of my thoughts too, there's something not right there. I'm over 6' and under 90kgs. Not ripped by any means, but some clear definition and pretty heavy set (I do a few strength and power related sports). Maybe his scales are fucked up I would have to say though, that on the basis of that photo, not his numbers, her may well be within a normal BMI range. The weights as recorded look wrong though so can't really go on them.
