Find me a good "weights won't make you muscle-y" article 4 a girl

[teddyFBI]

My GF's sister is staying w/ her this summer. I've successfully got my GF in the weight room, after tirelessly deprogramming her "but i don't wanna get big" mentality, and we're both reaping the benefits from it.

Her sister's a pain in the ass, though, and my GF wants to get her in the weight room too, but she won't go until i "back up my claims" -- i told her i'd find her a good article about how lifting weights will make her hot, not muscle-bound. I've read some good ones but am too lazy to go find them. Can anyone link me to a good one?

(and here, I'm Rickrolling myself to get it out of the way.)
