Hello Teen BB,
The following two pics are pics of my back. Both of which have been posted here before but I stumbled across the "before" the other day so I decided to post a before and after thread.
First pic was taken last november.
Second pic was taken two months ago.
In between this time (and up to now), I've been training for powerlifting, and accumulated a bit of mass as well. The after pic ain't really the best, I'll get a new one up this weekend.

Cheers.
