Now, I don't think that it is news for anybody that a regular bra won't support your bouncing breasts, I suppose that the number of women believing this is inversely proportional to cup size .

But still, even smaller chested women do need the proper support when excercising as breast pain isn't due breast size but bounce speed.

Now, looking back at the original article, there are some numbers that don't seem quite right:

In A-cup women, wearing a sports bra reduced overall breast movement by 53 percent, compared with a 55-percent reduction for G-cup women.

Only 2% breat movement difference between an A cup and a G cup?! Now, please tell us where to get those sport bras!

A pair of D-cup breasts weighs about 15 to 23 pounds (7 to 10 kilograms).

I really think they meant ounces here, and the Kilogram conversion of course is way off :-/
