What you eat and how much you exercise plays an important role in your breast size. Exercises are crucial and there are certain breast-targeted ones which if performed regularly can have a big impact.
Some of the most effective exercise routines you should follow regularly are pushups, lifting dumbbells, wall presses and chest presses. These can help you build up muscle in the breast area, enlarge your breasts and keep them firm and perky.
All of these exercises are quite simple and performing them on a daily basis will just take a few minutes of your time but will have amazing effects.
