Dangly bits

I have really baggy arms at the top now I have lost some weight. Does anyone have any exercises to help tighten them up. Also, I still have a tire roll around my middle, any suggestions for that too. I really do need to get in shape. I know  0 is a shape, lol

No exercise is going to change your skin. But muscles can fill out the space where some of the fat used to be. Plus, it's fun to be an old lady with guns.
