Left Arm at the side or on the chest at Impact Fix?

OK. I'm a little shy about asking this question because it may be due to my "body by KFC and Thickburger." But . . .

At Fix, should you have the upper Left Arm resting at the side of your chest or on top of your chest?

It seemed to me when I had the upper part of the Left Arm ON TOP of my chest, that it was easier to get my Right Forearm On Plane and pointing at the Plane Line as a result.

Any takers on this?
