Best Bench Angle for Skullcrushers?
I've performed flat, incline, and decline variations, and come to believe that the angle of the torso is meaningless. The focus should be on the angle maintained with the limbs during the movement. If the arms are focused on an angle where they are behind the head at the extension portion of the ROM, tension will be preserved on the triceps.
