1. Lose fat so you're less fat. Having a better face and jaw line is part of that bonus.
2. You're bone structure is of course directed genetically, however:
Bones are a dynamic system. Calcium is constantly taken out of the bones, and placed back in them. This enable regulation of the calcium pool in the body. Exogenous hormones (the ones you inject in your butt muscle in a vain and futile attempt to be like Arnold) will affect this process, and so will endogenous hormones. Since working out like a fiend will cause an increase in certain kinds of hormones, like testosterone, your facial structure can change over time.
Live like a man, and look like a man.
