Best exercises to get rid of cellulite?

I'm very happy with my body weight/shape but I would like to firm up my legs. I'm "bottom heavy" so I carry most of my weight in my hips, butt, and thighs. What are the best exercises for toning up thighs and reducing the appearance of cellulite on the back of my legs. Serious replies only please.
Thanks Sarah MA!

I should emphasize that I'm only looking for exercise tips that have worked for others. I'm not interested in spam comments about free trials of diet supplements.
