The arm should never completely extend. You should "punch the disc out" with a sudden direction change (of the arm/hand). If your elbow is locked, you'd have to unlock it before the direction change and you'd be decelerating very close to the hit.
I have a couple questions of my own.
How does the right pec drill differ from the closed shoulder snap drill?
I can't get my elbow as high as Beato's seems to be; is that critical, or should I just have it at a comfortable height?
Are there vids/pics of drills that start closer to the hit? It's called "working the hit backwards" but the hit is only the last 10% or so. I've tried working on it on my own, but my body positions are not right.
