I hope I don't fly away....

So this is for those who have lost a good amount of weight and are struggling with some loose skin.
A little bit about my background:
I have lost 120lbs and have just recently noticed slight wings on my upper arms and inner thighs.
I notice this the most when waving or using the elliptical, and my thighs look great in jeans, but look uber gross in shorts.

I"m not a HUGE fan of weights, but I know how to use them if need be.
Can you please suggest a few weight routines I can do to start firming up these 2 parts?

Like I said I'm thankful that it's not in other areas of my body for as much as I've lost, so any ideas you have I will try!
