Pay more attention to diet in peacetime.

Large pelvis is the root cause of thick buttocks and thighs.

Sit less and stand more.

Pay attention to the clamping of your legs when sitting, because you can put your legs together. Pay more attention to the clamping of your legs when you walk. You'd better walk slowly, and don't twist your hips. Then you can go to the beauty website to watch some skinny hip aerobics. Some are really effective. You can also buy some Chili oil and apply it to your thin buttocks or run more, but it is best to jog, otherwise the calf muscles will thicken. Tipping on the stairs or twisting your waist 50 times a day will help lift your buttocks and prevent looseness. If not, go to liposuction.
