your back is much more defined and toned .. is what I am seeing anyways .. probably what the others are seeing as well and your arms .. they have that lil muscle curve to them ... you look great! congrats!
you look stunning, and you can deffinetly see a difference in the top of your back and legs. I could not see toning (but i cant see through material lol) but it looks amazing, im very jealous of those legs too :-( lol one day maybe
I cannot take credit for my legs at all. I was a sprinter in high school, so I have to thank my track coach. But once I started working out again, my muscles just remembered what to do, I guess.
