Cardio will only decrease the fat on your body, and will likely make your breasts SMALLER!!! Generally, avoid too much cardio if you're looking to get boobs (although if you're very active, that's great, just know that it is probably going to hold back your boob growth if you don't have enough fat on your body).

Also, push-ups are great for building the pectoral muscles, which help make your breasts look larger and perkier. You can give that a try along with massage and hypnosis!
