What turned you into a kinetic link man???Physics??????Crack the whip baby!!!!!!

I see a flexed front side, hips already starting to open and getting ready to open more as the front leg torques the front hip back (at the same time the back leg turns over and torques the back hip forward) : both hips turning around the stationary axis of the spine!!!

> Those trailing figures are obviously replicas and offer no additional information about that swing..I just found it ironic that a site dedicated to discrediting the positive effects of weight shift in the baseball swing would display an image of a batter employing linear mechanics..I would go as far to say that this player will not be able to perform the "ideal" kinetic link..This batter has actually allowed too much weight to move forward before blocking with the front leg and conserving energy to be transferred throuhout the rest of the system..He has also made the mistake of bringing his hands forward with his weight shift..The hands should stay back (lead arm extension)until the hips open (blocking i.e. transferring)which will transfer energy to the shoulders which then open and block, sending energy to the arms which should remain back until this point...All physicists know that the ideal kinetic link produces high bat velocity by the sequential transfer of energy from the stronger and heavier body segments (legs and hips)to the arms and finally the bat. Our friend should continue to employ a strong weight shift with a closed front leg, it is the beginnings of a strong kinetic link..He should work on stronger blocking against the front leg, this will initiate a quick and powerful hip rotation (keep the hands back).... He must also work on gaining lead arm extension during the stride forward/weight shift..

>this discussion is absurb.........it's difficult enough to even look at a video clip & agree on whether or not the hitter is rotational or weight shift, so trying to make judgements based on a diagram, shadows, etc is rediculous............why not go over to the posts regarding weightshift vs. rotational characteristics and have a more substantive discussion?....respectfully, grc........
