Rotator cuff training should reflect how your rotator cuff actually works.
These muscles help stabilize the shoulder when you LIFT YOUR ARM.
Given this information, why would you only train it with your arm at your side? This is arguably the position at which your shoulder needs the LEAST support from the rotator cuff.
Rotator cuff exercises need to involve the less stable positions (overhead, lifted out to the side, etc.) to train its ability to stabilize in these positions.
