I am 6' 2" and at my lightest as an adult I was 147 (Rockclimbing for a living) and my heaviest around 185 (Grad School). Now I hover at around 165-175 depending upon my activity level. Ironically though when I was climbing I looked bigger than I do when I am cycling a ton. I guess its all on how it is distributed
me really light and climbing (rocks) well
me 20 plus pounds heavier but looking way skinnier.
