Do more hip twisting exercises. Or sit up straight in the chair, with your feet facing each other, and press your upturned knees hard with your hands for 15 minutes every day, which should be effective. . . Just try it. I also think it's better to be small. If you really can't, you will lose your waist. It is easier to lose weight. Do 60 sit-ups every day, turn 200 hula hoops, stand more, eat more vegetables, eat less meat, and drink soup before meals. If you insist, it will be effective in 2 weeks. . . You can also try. It's your choice.
