Old Forum Hands internally or externally rotated during push ups?

[SupermanBeyond1938]

Hey folks I always thought that during push ups you weren't suppose to internally rotate your hands but this article is suggesting otherwise.

My understanding is that the hands should be in neutral position (straight) with a slight outward rotation applied against the floor- but not actually changing the actual position of the hands.  Other thoughts?
