1, strengthen chest muscle exercise. The pectoralis major is developed and thick, and the chest can be raised very high. In order to strengthen the exercise of chest muscles, we can insist on doing push-ups, horizontal bar pull-ups, parallel bars stretching arms and various ball games. 10 minute aerobic warm-up +45 minutes strength training+10 minute stretching, remember to adjust your breathing. 15/ group, each group will rest for 20 seconds, and come to 8 groups.

2. Keep the correct body posture. When walking and sitting at ordinary times, you must develop the correct posture of holding your chest out and abdomen in. Every morning, keep doing chest expansion exercises, put your arms or elbows flat, stretch them backwards as far as possible, then lift your arms up, palms forward, and push them backwards.

3, often do chest and breast massage. Massage will strengthen the blood circulation of the chest and breast, improve the metabolic ability, and make the local flesh full and elastic. At the same time, breast massage can make the sympathetic nervous system and parasympathetic nervous system active, thus promoting the development of the breast, and the breast will be plump and keep a beautiful curve. The method is: put four fingers together and separate from the thumb, press the breast and massage yourself rhythmically, from light to heavy, repeatedly. 3 ~ 5 minutes each time.

5. Take part in swimming activities. Because of the pressure of water on the chest, not only the respiratory muscles can be exercised, but also the chest muscles will be particularly developed. Under the mild stimulation of sunlight, the toughness and elasticity of breasts will be enhanced, which will make breasts firm, firm, full and beautiful.
