You can get up early to climb the mountain every day, so that your legs can get all-round exercise, which will quickly reduce the fat of your thighs and possibly make them more slender by stretching the muscles of your calves. About thin waist: One way is to spend an hour twisting your waist in situ every day. Of course, you can also do it with music. Another way is to use professional equipment to exercise the waist. About thin hands: this question is more difficult. The key is perseverance, which must be well adhered to, otherwise the effect is not obvious. The method is to wash your hands and rub them with edible salt for 5- 10 minutes every night, and then soak your hands in 35-40 degrees hot water for about 15 minutes. It is best to add some vinegar to the hot water. Remember, you must stick to it every day!
