This is very irrational. Think about how delicate a woman's breasts are. Even when taking a bath, the requirements for water temperature are very strict. Why talk about such exciting things? The best way to lose weight is to exercise chest muscles, and women can also exercise. For example:

Simple weight lifting

1. Lie on the ground and bend your knees.

2. Hold dumb poison in both hands and extend it to both sides. Elbow slightly bent, about four inches from the ground.

3. Slowly lift the dumb poison and exhale.

4. Slowly put down the dumb poison and inhale.

5. Repeat the action 3 and 40 times.

Changes in palm pressure

1. Kneel on the ground.

2. Bend forward and put your hands on the ground. The distance between hands is approximately equal to the shoulder width.

3. Keep your back straight and your hips tight.

4. Bend your arms slowly and rest your chest on the ground.

5. When you reach the bottom point, slowly push your body up and return to its original position. 6. Repeat this action 4 to 50 times.
