Yeah I noticed the arm thing too. I guess it helps me get the shoulders lined up or something and that's how I started doing it or something without even noticing LOL! I'll focus on that arm.
Am I popping the right arm out too early? I am aren't I?
Oh, check out your PM on you tube I send you a pic of my bielman

that one's coming along nicely too.

I'm actually enjoying stretching for it, makes my back feel all relaxed afterwards.
Thanks for the comments!

I'll try the rolling thing, it sounds good.
