It should be hard. It's not necessary. If there is fat in the waist and abdomen, you can try sitting in a chair, with your body and thighs at 90 degrees and your back straight. Put your hands on your thighs and grab the edge of the chair. Exert your stomach, count to five slowly, and try to lift your knees to your chest. Pause at the highest point, and then slowly put down your body at a speed of slowly counting to five. The effect of this action can eliminate abdominal fat and tighten abdominal muscles. But be careful, your hands don't need to be hard, just put them on your thighs easily. Moreover, the body can't lean on the back of the chair, and you must be able to clearly feel the stomach exerting force. Do this action according to your own ability, but it is best to work in groups of at least six people at a time without interruption. You can take a break and repeat a group.

It is difficult to lose weight in the abdomen. If you don't want to exercise or go on a diet, you can also use liposuction to lose weight, and the effect is better.

Liposuction to lose weight is a method to improve obesity by using a high-tech liposuction instrument to connect a professional suction tube and enter the subcutaneous through a small incision in the skin to suck out the local accumulated adipose tissue. Because fat cells are fundamentally reduced, they won't be fat again.
