I have the same issues. I've almost gone done 2 pants sizes, which is great, but my arms are still exactly the same. And now they look bigger because of the strength training. Yuck. I figure my body will have to get to them some time though, so all we can do is keep going.
I can not believe you all are writing exactly how I feel. I have lost 10 pounds and my pants already feel less tight and My wedding ring fits so much better. But I suppose it will take an enormous weight gain to loose in my arms. A lady I work with had gasteric bypass and even after a 100 pound loss her pants are still big
