I don't mean to sound personal, but what are your measurements? And your height? And do you have an idea of what your body fat percentage is at the moment? What I'm getting at is this: If your body fat is low, say under 22% (according to Covert Bailey, at least) you may simply have a lot of muscle in your legs and rear. I know I do! It's genetic, even my brothers are shaped like that! But I found that doing squats and lunges just made that area bigger, not slimmer, since I just build more muscle on top of muscle.
What has worked for me is cardio on the bottom half just enough to keep things tighter and reduce cellulite, and resistance work on the top half of my body to build me up and balance out my figure. So now I'm 43-35-43 (still big, I know) but not pear-shaped. And it also helps the bustline stay perky, if you know what I mean. Actually, you probably don't at your age, but trust me, gravity happens, lol!
IMO, it's not about hating any body part, it's about making the best of the genetic cards you were dealt. Good Luck.
