(1) The flat support is relatively simple and easy to learn, and it can exercise the transverse abdominal muscles, so it is a consumptive exercise method. It's hard to stick to it at the beginning of learning. You can do some basic movements first, straighten one arm and then lift it horizontally, and the elbow joint of the other hand supports the body to maintain balance. Insisting on exercise can improve the waist and abdomen lines.
(2) Sit-ups are a common method to reduce stomach. You can do it in a small range at first, but pay attention to the waist strength, so that the abdominal muscle activity will start from a small range and continue to increase in the later period.
(3) When the abdomen is rolled, the angle between the body and the ground is generally about 30~45 degrees. Don't go below 30 degrees when you go down, and don't go above 45 degrees when you get up. You always use your abdominal muscles to exert your strength. This exercise is a little more difficult, but the effect is very good.
Besides exercise, diet is also very important. Eat seven minutes full every day, eat more vegetables, and eat less high-calorie foods such as frying. It will be better to cooperate with exercise.
