cruc - I am in the same boat. I am 5'9" and weigh about 178-180 lbs. I have little to no body fat whatsoever, very broad shoulders, thick legs and extremely dense bones. I think my weight is perfect for me. I was built this way and I am going to make the best of it riding. I always have wondered what it would be like to look like Armstrong and if it would be an advantage in my riding. But that is short winded because I ask myself if I would like to look like Armstrong or Nelson Vails. My choice goes to Vails!!
