I want to share a portion of the members’ inputs in Yahoo Answers where I am an active member, in one of my questions that gathered really good feedbacks. 

Here is the question:  There are lots of exercise equipment sold on TV Shopping Channels. I just wonder if they are effective. Do exercises help in increasing bust/chest size? Or does eating more protein food or fatty food help as well?

The answer is No. What they do is strengthen the muscles that underlie the breast, so it gives the illusion of size, but no actual bust size increase.

Every woman wants to have great breasts. Here’s a quick anatomy lesson. Your breasts are actually made up of fatty tissue, so their size depends upon how much fat you tend to store there, which calls in factors like your genetics, your weight, your health and your age.

The muscles that reside directly underneath your breast are called the pectorals. They are partly responsible for the ‘perkiness’ of your breasts.

You can’t do anything about the size of your breasts (short of gaining weight or having surgery.) However, you can make them appear bigger and firmer by developing your pectoral, or chest muscles.

The Modified Push Ups

Lie on your stomach, bend your knees, and cross your ankles. Bend your elbows and place your palms on the floor just to the side and in front of your shoulders. Straighten your arms and lift your body so you’re balanced on your palms and knees. Tuck your chin a few inches toward your chest so your forehead faces the floor. Tighten your abdominals.

Bend your elbows and lower your entire body in one motion. Rather than trying to touch your chest to the floor, lower yourself only until your upper arms are parallel to the floor. Push back up. Don’t lock your elbows at the top of the move and don’t do the dreaded ‘head bob’ (when you dip your head toward the floor without moving any other part of your body).

Dumbbell Press

Lie on your back with your feet flat on the floor and a tin of soup or a dumbbell in each hand. Make sure the dumbbells are of equal weight. Push the dumbbells up so your arms are directly over your shoulders and your palms face away from you. Pull your abdominals in but don’t jam your back into the floor or let it arch upwards. Tilt your chin in toward your chest.
Lower the tins of soup down and a little to the side until your arms make a 90 degree angle and your elbows lightly touch the floor. Push the weights back up, taking care not to lock your elbows or allow your shoulder blades to rise off the floor.

Incline fly

Lie on the floor with your head, neck and upper back propped up against several large pillows. Hold a dumbbell in each hand and press the weights directly above your chest, palms facing each other. Tuck your chin to your chest to align your neck with the rest of your spine, and maintain your natural back posture, which is neither arched nor flattened.

Spreading your arms apart so that your elbows travel down and to the sides, lower the weights until your elbows lightly touch the floor. Maintaining a constant bend in your elbows, lift the weights back up, imagining that you have a barrel lying on your chest and you have to reach your arms wide around it. (www.ivillage.co.uk)

Dumbbells can be replaced by soup tins if dumbbells are not available.
