A frequent complaint among women during the sunny seasons is that unsightly skin that rests between your arm pit and your chest. While body fat could be the culprit, changing your diet alone won’t always solve this issue. If you’ve noticed women with implants have very little of this extra tissue. That’s because increasing the size of your chest by adding muscle or implants (in their case), can fill out that skin. Doing chest exercises paired with back exercises can help fill out that problem area.
