Remember that John Smith knows how to coach….the accleration is set by the natural rise in the hips starting from your first step. Any attemped to artificially enhance your accleration to stay down longer will hurt performance. What the cue is to allow your steps to create the shin angles and not making the error of popping up. All phases are seamless…this is why Mo had the best run of his life in Athens with a smooth set of transitions. I will admit that pressing down is a great way to get use to being in a forward lean. This is all based on power levels from the start….
