OK, so I have enormous thighs. Huge. There are tree trunks that are smaller than my upper legs. Over the last 3 years, I have lost about 20kg. Most of this seems to have gone from my waist, my calves, and maybe a little from my thighs, but really not much. They are huge. The rest of me is a 12, but my thighs are more than happy in a 16, or a big 14.
I currently cycle (on real roads with big hills) 30km a day, swim 2km twice a week, but that's it.
What should I do next?
What can I do to rein in these enormous (like, really, bigger than some European nations) things on the lower half of my body?
