Doing sit-ups is simple and effective to practice abdominal muscles. You can also lie flat on the bed and touch your toes with both hands (lift your body). Do it slowly. If it is fast, there will be inertia, which will affect the effect. Be sure to do it to the end and do it in place. Each group does the limit. Remember not to do it every day, but every other day. Every time you do anaerobic exercise, you should destroy your muscle tissue as much as possible, and then use enough time and nutrition to repair the damaged muscle tissue and let it grow. To put it bluntly, muscles grow out at rest after anaerobic exercise. You also need to lose belly fat through aerobic exercise. 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. If you simply do sit-ups, the fat layer will not decrease, the muscle layer will thicken and the waist will be thicker. Only scientific fitness can have perfect muscles.
