When sitting, put a thick magazine or book between your thighs and knees and exercise every day whenever you have the opportunity to sit. The effect is to tighten the muscles of thighs and buttocks, burn fat, and the thighs will be thinner (and there is no cost). You can wrap the calf outward with the broadband under the knee and wrap it tightly for an hour and a half. Don't do it while sleeping, it will easily affect blood circulation. You can also buy a special belt. I have one with only a little leg.
