Stand against the wall after dinner every day, get as close to the wall as possible, and pull the whole person up.

Girls can try stepping on the edge of the steps, or in a book (refer to the thickness of the Oxford dictionary), pulling their heels up and holding them in the air.

Hold the wall with both hands and palms, don't squat hard, keep your upper body upright, hold your chest high and raise your head.

When standing and walking, subconsciously put your shoulders back, raise your head, lean your neck back on your collar and correct your posture.

Stick to it for a period of time, and the whole person's physical condition will definitely improve.
