Upper abdomen: The upper abdomen is a part of the stomach. The easiest way is sit-ups. Attention, not sit-ups! If you sit up when doing this action, it is not good for your spine. Don't put your hands behind your head when doing this. Just cover your ears with your hands, or you will hurt your cervical spine. Do at least 3 groups every day, with 20 in each group.

Lower abdomen: it is a "small belly". Lie flat, legs straight, feet together, slowly lift, make a 90-degree angle with your body, and then slowly put it down. This action will be very tiring to do, but it can also reduce the fat on the front side of the thigh. Do at least 2 groups every day, one group 15.
