You can't change your bones, but from a muscle point of view, you can visually change your waist-leg ratio through exercise. On the positive side, only by reducing thigh fat and improving muscle tightness can leg length be visually improved. After that, you can exercise the hip muscles, make the hip muscles tight and upturned, make the hips narrower and upturned, visually lengthen the proportion of lower limbs, and reduce the visual length of the waist extending to the hips. So what you need to do is to do more aerobic exercise, reduce leg fat, fully relax thigh muscles after each exercise, and make leg muscles slender rather than stout. After aerobic exercise, you can do some local exercises of hip muscles and relax hip muscles after exercise. If you are at home, you can buy a sponge massage roller for yoga to relax your muscles after each exercise. Most gyms have this.
