Chris is right. There are those out there who say that rotating the hips into landing is foolish and that it must happen UPON landing, not before. Now that's foolish. Just look at video of MLB pitchers and you'll see how foolish. Stride sideways, aggressively, to build up momentum and rotate the back foot, leg and hips just as you are about to land, or have to land. If your timing is correct, meaning that the shoulders are still lined up with second and home when the front foot lands, you'll have good separaton between the hips and shoulders, which, as has been discussed many times on this board, creates a stretch across the torso that fuels a more powerful shoulder rotation and trunk flexion.
