Bonds is raising his hands in the gif.
Hands aren't above or below the humerus. When the gif comes to a stop.LOL ... it is the raising of the hands that adds clarity to the external rotation that is taking place.
Wouldn't Bonds humerus be in a neutral position in this gif.
Hands aren't above or below the humerus.
I am the one laughing.....
I'm laughing even more now. You are now in a mode of making crap up.
In your image the movement from the arm in the lower position, to the arm position in the middle, the rotation taking place would be 'external rotation' ... even though the hand is below the humerous.
I'm thinking you're making up crap.........I don't see it the same way you think you see it. I know it's early in Portland.
To follow-up ... I marked up your image. The term 'internal' and 'external' is meant to describe the direction of 'rotation'.
