Let's do this by every 20 lbs. So it would go like this
(Say you are 5'8''.)
120 lbs - 11.5 inches
140 lbs - 12.5 inches
160 lbs - 14.5 inches
180 lbs - 16 inches
200 lbs - 17 inches
Would this be about right? I'm thinking of averages not genetic freaks.
Post your weight, height, and arm size so I can see an average.
