Judging from the body mass index (BMI), your weight is within the normal range, but I don't know how high your fat ratio is. This should be measured with professional instruments. When it comes to reducing fat, aerobic exercise is of course the best, but if you don't exercise much before, it will be unbearable and easy to cause harm to your body. In addition, it is best to combine anaerobic exercise before aerobic exercise, so that aerobic exercise can get twice the result with half the effort and not take too long. It is best to exercise every other day. Remember to exercise on an empty stomach, properly supplement protein after exercise (especially combined with anaerobic exercise), warm up before exercise to avoid strain, and stretch and relax muscles after exercise. Your persistence, good luck!
