Many
waitresses experience an
enlargement of the breasts after working
steadily, up to a half a cup size or so. My current
girlfriend went almost into the next
cup size while she worked in a
restaurant for some time, due to the increased chest
strength, and use of muscles in that region (
lifting above your head, holding trays, etc). The increased
blood flow to the area is
significant and actually does make breasts
bigger.
The increase is
muscular, and thus is subject to how often you continue such
exercises, as with any other
workout; simply "playing" with them is not enough to build consistent volume. Pectoral exercises aimed at
muscle tone will enhance them, and as with any
body building routine, it comes with the added bonus of making you more
healthy.
Many women employ external items to make their breasts
look bigger, such as stuffing, the
wonder-bra, and
implants; the more extreme the
measures, the greater the risk for damage.
Breast size isn't everything, and especially
large breasts can be bad for a woman's health. As with everything in life,
balance is the key.
