Trying to help my sister

My sister wants to start working out with me, but is sort of in the "what's the point" frame of mind right now. A couple of years ago, she lost about 120 lbs fairly quickly and with no exercise. As a result, she has loose skin that makes her very self-conscious. I told her that exercise isn't useless to her and that there are lots of people who have improved their loose skin situation. However, I can't seem to find the thread I was looking for in order to show her the proof. Is there anyone willing to help my sister out by posting some before & after photos?

She's one of the kindest and most awesome people in the world, and I'd love to be able to give her that extra boost to start gaining some confidence in how her body looks.

Thanks in advance.
