It is estimated that it will take around six to eight months for you to see results from your exercise and diet regimen for larger breasts. However, the size of your breasts may not be fully attained until several years later, depending on the intensity and frequency of your workouts and the types of food that you consume. When it comes to achieving larger breasts through exercise and a balanced diet, it is most effective to combine both methods. To get the best results, make sure that you are following an appropriate exercise plan that includes weight-lifting, cardio exercises, and muscle-building exercises. Additionally, make sure that the food that you are eating is nutrient-rich and full of healthy vitamins and minerals.
