The hips and shoulders do not go backward as the hands go out and around. It stays where it was after the stride or prep movement took place.

> > The most detailed useful info I have seen is from Mike Epstein's video-I hope Jack doesn't mind my mentioning his info.It is important to "trigger" the lower body with the front heel coming down and begin rotation with weight staying back on the inside of the back thigh( weight feels this way in throwing too).Lunging results from getting weight any more forward(onto the front thigh for example).

> i'm glad someone brought up the action of the rear leg and its importance to the swing. after reviewing some film of ramirez, griffey, jeter, and garciaparra, i think that it is evident that the rear knee is what allows the hitter to rotate to the back toe. once the hitter lands on stride, the rear knee works towards the lead knee, thus rotating the foot to the toe. the hitter does not simply elevate to the toe - it is the action of the back knee.
> secondly, i do not like hitters to "squash the bug." i think this term was originally used for kids who had zero rotation and flipped with the hands. now it has become abused and used in the wrong context. if the hitter simply squashes the bug, he will leave too much weight over the back foot and collapse - many times allowing him to fall below the plane of the pitch.
