Anybody know of any fitness models with nice round butts and tight bodies?

I need motivation. I want to strength train to build a lean slightly muscular but still feminine body. Keyword: LEAN. I want to follow fitness models and learn their routine. I am already doing a routine that works different muscle groups each day.

I hate to offend anyone but honestly alot of the fitness models that lift look manly. I don't know if they are taking steroids or going over board but I definitely don't want their routine. It's hard finding a woman who lifts and has a lean feminine body. Also one that eccentuates the natural curves of a woman's body. I just don't want to be big and bulky like Serena Williams or alot if these chicks. Any suggestions???? Please include websites or YouTube names. I really want to start tweeting my routine for maximum results.

Update: thanks girls! All these suggestions are great!!! Exactly what I was looking for!!!
