Having just measured mine out of complete boredom, I am now confused.  When someone says their arms are x inches or 15 inches is respectable, is that flexed/unflexed? "hot"/"cold"?  Because mine are smaller than smalls, I swear to God, they are pathetic, not terribly unlike the rest of me.  But they are just a hair under 15" flexed/cold.  I assume it's measured around the whole arm, at the widest point? rippedtrojan, how tall/heavy are you?  Maybe I'm missing the ratio thing.  I'm a tall motherf'r, so I could still be as pitiful as I think I am.
