Best excercise routine to tighten butt and lose cellulite thighs?

here's what helped me and i lost over 70#... i started out on the elliptical trainer and stair stepper, i couldn't do very much at first but i would do about 10 minutes on each every day, and every few days to week i would add just a couple of minutes (i got up to 65 minutes of each every day to every other day). after i built up a little more confidence, i began taking a dance class, tae kwon do, and pilates. tae kwon do seemed to help the most, since it involved lots of kicking exercises. i also started doing squats, boy my legs hurt! but man oh man they sure toned up so well. i did the squats on the smith machine, just begining with the bar (45#) and building up every couple of weeks. if your going to a gym ask one of the trainers to show you proper technique so that you don't hurt yourself. (by the way, i'm female, if that makes a difference)
