Article: Despite the fluidity of swimming, it takes a considerable amount of strength to do steadily. If you have access to a swimming pool, this can be an easy way to firm your breasts and get a great workout. Practice doing freestyle strokes, breast strokes, and butterfly strokes to engage your core and chest muscles. While these may seem difficult to do at first, doing push-ups is an easy way to increase your muscle endurance without needing any extra equipment. As you increase your reps overtime, the muscles in your chest and core will strengthen and firm, lifting your breasts.  Your back should be straight the entire time when you are doing the push-ups. If your back bows, you will not effectively work your chest muscles. To help build up your muscles, you can start by doing push-ups on your knees, and then gradually work up to being able to do a traditional push-up. The weights will provide resistance to your chest and shoulder muscles, and will overtime lift your breasts. You can either use dumbbell weights or bar weights, whichever you are most comfortable with using.  Begin by lying flat on your back on an exercise bench and hold the weights with both hands. Keeping your back flat, push the weights away from your shoulders and into the air. Inhale as you bring the weights back down to your chest, and repeat the process 10 more times.  Bench presses can be dangerous since you are lifting the weights directly over your head. Make sure to have a spotter with you in case of an emergency. Once you build up your muscles from the bench presses, you can transition the same technique into a dumbbell-fly exercise. This is an easy way to target extra muscles, and you can even do this exercise standing.  When you push the weights upwards for the bench press, exhale, and spread out your arms like wings until the weights are level with your shoulders. Keeping your arms straight, lift the weights up, and then bring the weights back down to your chest. Do not start doing this exercise with heavy weights as you can easily bend or twist your wrists. This is a simple exercise that can be done at home, or between commercial breaks when watching television. To get started, you only need a small exercise ball, or a small playground ball.  Press the ball between your palms. The ball should fit comfortably between your palms, and have a little weight to it when you lift it up. Take a wide stance like you are mid-squat. Your knees should be bent at 90-degree angles, and your toes should be slightly pointed outward. Bend your elbows and bring the ball to your chest. Then extend your arms over your head, squeezing the ball tightly, while simultaneously extending your knees halfway out of the wide stance. Bring your legs back to the original squatting position. Then quickly pulse your legs upwards as you bring the ball back to your chest. The movement should be fluid, almost like a small bounce, before settling into your starting position.

What is a summary?
Take a few laps in a local swimming pool to firm your bustline. Do traditional push-ups to engage your chest and upper body muscles. Do weighted bench presses to tighten up your chest muscles. Transform your weighted bench press into an advanced dumbbell-fly exercise. Perform a high-low ball squeeze with a small exercise ball.
