Well I have been reading some cycling material and other peoples posts and I find my self stareing in shock at what a lot of people are weighing in at. I am 5'9" and 166lbs. I don't get how I could be over weight as I am a lot smaller than my friends of the same height. Is it just a different build muscle? I have a rather thick upper body, but defined (not cut) abs, and pecks(sp).
