Training breast enhancement can start from several aspects: 1. Chest enlargement exercise, which is the simplest movement, is like the warm-up exercise taught by teacher physical education class. 2. Push-ups, if women's strength is not great, it will be easier to do the fulcrum with both feet kneeling (and do what you can). 3. Barbell bench press, if possible, you can go to the gym to do this action, and the weight should not be too heavy to avoid injury. 4. Massage every day to circulate blood in the chest and strengthen metabolism. The first three strength exercises can make the chest muscles firm, thus making the whole chest firm. Note: These strength exercises should be done for 20 minutes every day. Training focuses on moderate weight and multiple times, which can make the chest muscles firm and make the chest more stylish, thus making the whole chest firm and changing the sagging situation.
