tone up around your armpit area << Oh my. Now we have to worry about our armpits?!? Frankly, I think the only way you can 'tone up your armpits' is if you lob your boobs off as they are all one in the same. This pin is because we are so used to seeing women who are super slim and would naturally have no breasts, get implants, hence, no breast tissue near pits, and 'armpit issue'.
