All aerobic exercises are good ways to lose fat, such as running, skipping and swimming. There is also summer, buy a disposable raincoat to wear, run at home (don't turn on the air conditioner), wave your arms quickly and sweat more, which can reduce fat and detoxify. Replenish water in time. The above exercises should last for more than half an hour at a time, otherwise they will be invalid. I recommend a very time-saving method to reduce waist. When watching TV, sit in the corner of the sofa, hang your legs upside down close to the armrest of the sofa, put your hands on your chest (you can cross them), and turn your waist at the maximum angle. In this way, you have already consumed the fat around your waist when watching TV. Eat less high-calorie and high-oil food.

Never do sit-ups. Sit-ups belong to anaerobic exercise and have little effect on reducing fat. If you only do sit-ups without aerobic exercise, the fat layer will not decrease, the muscle layer will thicken and the waist will be thicker.
