Hey Dustin your weight is in a good range for your height. You describe yourself as being small framed right? Medium frame guys at your height may weigh a little more but you are at a good height.
I am 5' 9" and weigh 145 but i am small framed. Thats is the proper weight for me. Its better to be a little thinner than a little heavier. Obesity is a huge prob in the US. Especially with kids now a days. It leads to many diseases. So sounds like your at the right weight for your height...Peace out...
