Welcome to this group. I can tell you one thing there are a lot of people in this forum with a lot of useful information and experience. Any questions you may have just ask. So I have the same issue as you "bat wings" and i have always had this issue since my weight would fluctuate. However, since i am awaiting for my surgery I have done some research and getting serious about getting rid of my wings.
I found 2 wonderful sites with great exercising tips that will help.
First one is: www.nowloss.com this is a workout routine to get rid of flabby arms or arm fat. It has video, which I love, because i am a visual person.
I am thinking for myself to mix them up and create my own but at least they gave me wonderful ideas. Anyways, let me know what you think and best of luck to you.
