Arms are getting bigger.....help!!?

I started poling in December and I am learning tons....loving it! And aside from the bruising, front foot soreness and other small complaints that are all worth it, the one I'd like to fix is the fact that my arms are getting bigger.  I already had very large fat arms, now they are becoming very, very large toned arms.  I am a plus sizer who does hope to drop pounds and now shirts and suit jackets are starting to no longer fit.  They are tighter in the boobs and the arms......yowser.  Although the waisteline and hips are certainly looking much better.  I don't want to be any more top heavy than I aready am and I certainly would like to shrink my arms.  I am gaining strength but can't I have both smaller arms and strength?  Any suggestions?
