1. To lose weight, you must first adjust your posture. There is no doubt that more than 80% of abdominal fat accumulation is caused by many bad habits in daily life, and sitting posture is the number one killer. The hunchback, including the chest, will make fat accumulate at the waist, and over time, an ugly "life buoy" will appear. Correction method: The cushion with the function of adjusting the spine can well support several fulcrums of the back, make the back straight and reduce the production of fat. 2. Sit after dinner? You are in danger. Many people are used to sitting or lying down after meals. In fact, this practice is very unscientific. The calories you eat will turn into fat on your waist, but it is wrong to get up and exercise immediately, which will keep blood in your stomach.
