Although I'm not fat, I have a very simple method that doesn't cost extra money. When watching TV every day, or brushing your teeth and washing your face, your legs should be shoulder-width apart, and then make a March. Be sure to keep your upper body straight, especially your waist. Try to make an S shape, and then twist your hips left and right. Your body must not relax, you must twist to the limit, and feel the muscles inside and outside your thighs, hips and waist tense. It sounds difficult, but it's easy to do. As long as you do it in your spare time every day, you will soon see the effect ~
