Ok you are talking about stride? And you don't think there is resistance during that move forward? I really don't care if a hitter strides or no strides as long as launch is barrel movement around the hands.
You talked about pull backs right? Pull backs are casting agents. These guys try to keep the hands loose and free so they can be loaded during the forward move. The resistance is against the negative move. The hand set you see is from this resistance. Not pulling anything back.
