Underarm/back fat?

Hi, I was wondering I have this like fat that is apart of my under arm and boobs at the same time lol. Do you know what I'm talking about like the bra strap area. Can someone tell me how to get rid of it? please. I really hate that it ruins my outfits, because even when I feel I look good it's always there. It's the "confused" fat it doesn't known if it wants to be apart of my boobs or my under arm or back lol..
(Any exercises to do to slim it)

Don't know if this is what you mean or not.   Basically I have little pockets of fat that are sort of separated from the breast and just in front of the arm-pit.   Unfortunately for me it is "displaced breast tissue" according to my OBGYN.  When I had my kids it filled with breast milk just like my breasts and was very uncomfortable because it hurt to put my arms down by my sides.

So, if yours is the same, then other than surgery or losing enough to lose your breasts (not a good idea of course -- lol) it's not going to go away.  If yours is more to the back, then it may not be like mine... not sure from your description.

I don't know you are suffering from displaced breast tissue but sometimes finding a proper fit for a bra can make a huge difference.  Usually with the "back bulge" a bra is too small causing a "bubble" sometimes referred to as a back boob :)

Besides cardio to lose weight, you can do a number of exercises with weights, resistance bands, or just the resistance from your own muscles. One good exercise is to kneel one knee on a weight bench and keep one leg standing; one hand firmly supporting on the weight bench and one arm extended with weight in hand.  Do 3 sets of 8-10 repetitions.  I have found a book that shows different exercises "Change Your Body Shape"
