If you naturally have a different build, that's one thing. Some people have to work a lot more than others to achieve the same goal.
I've gone from maxing my benching at 90lbs to about 180lbs. I may not be getting big enough to look any better than average, but I'm making real progress that will legitimately help me.
Edit: Going into the Air Force for 2-3 years?
I enlisted in August. I started working out 2 months ago.
