I'm shrinking everywhere but my arms!!!

OMG...So there I was at my Zumba class Tuesday *which I LOVE* and decided to rock my new work-out gear. I have been so proud that I'm FINALLY in juniors (xl) but none the less, a junior size! Anyways, we're doing the workout and the gym is covered in mirrors. I notice that my arms, compared to my body, are huge STILL. Flapping around like nobodys business. Everywhere else I thought I would have a problem with skin isn't happening. My tummy is getting flatter and not too much of a skin issue, same with my legs (they're looking AMAZING). But my arms? I'm going to the gym which will help tone the muscle underneith, but I'm disqusted with the "bat wings" that are going on! I've lost a total of 20" right now and only 1 of those inches are from my arms... 1/2" off each.
As long as I don't lift my arms, they look ok.

Here's a pic (hair looks AWFUL)

You'll lose at different rates from different places.

But yeah, you're going to have batwings. Almost everybody does, unless they get plastics.

Keeping it up at the gym will minimize (but probably not eliminate) them though.

Yoga planks and push-ups will help but ultimately surgery will be the only thing to eliminate batwings.   If you do the push-ups now the surgery will look so much better later.
