Need bigger chest and shoulders...

For a little background, I've lost a few pounds this year due to some diet and exercise changes. Recently, there has been concern amongst loved ones that I'm anorexic. I'm pretty sure I'm not, but that doesn't alleviate the concerns. So, after getting feedback from Trina that it is my shoulders that make me look boniest, I've come up with a strategy to beef up my shoulders and chest. I've started doing bench presses instead of just pushups. I've added a few other chest and shoulder exercises, too. We'll see in a month if the changes are noticable enough to quiet the concerns over my weight loss...
