I'm 26 yrs old and about 130 pounds. I have not done any heavy working out, but over the past few months I have done push ups to build up my chest a bit and it has worked. I used to have nothing there and now I actually have pecs. The problem is that my left pec is fuller than my right pec. What can I do to even them out? It seems that even why I try to put pressure on the right, I still feel it more on the left. Please help!
