How do you lose weight on your legs and bum quickly?

Ho run, you need to know two things, first is that weight loss isn't quick, our bodies aren't designed to burn fuel that fast, and secondly, fat is distributed evenly all over your body, it just looks like theres more in one place then another, so you can't directly reduce fat from your legs and bum alone, all you can do is run/swim/cycle and lose weight overall. Eventually your legs and bum will thin out along with everything else.
