Capsule Stretch Arm Angle

Hi,

Can someone clarify what is the angle at which we should keep the arm under our body? Should we try to cross the arm such that it is directly under the opposite shoulder or below the opposite pectoral muscle or somewhere in between?

The angle of the instruction video doesn't show this detail.

Thanks!

I was wondering the same Giovanni.  My arm tends to be bellow my opposite shoulder.  As a general rule if my body has a tendency to do something naturally then I assume its not the optimal form .

It goes pretty much straight across.
