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..

I bet this was a picture picked out by a company that created the web site and not by Jack's choice.I can see the same problems in the picture simply because at that snaphot some body parts are not where they should be for where other parts are.Looks like a pitcher or someone taking a pitch and drifting through it.

> I think the shadow pictures are the same image,so let's just deal with the single best seen "top" image.Looks like real stop action to me and not a "set up" still shot.Looks like this player is at or just after "launch" if you define this as the front heel being down and the hand path starting forward.Head and body look in good position to me.Elbow needs to be down by this time,it is.There is still some separation,with hands and shoulders back and hips open.

> The appropriate footwork to get the hips open seems to have happened.I can speculate that the back knee flexed out to home plate to keep the weight from going too far forward with the stride.The hips started to open as the back knee began turning down and in and the front knee started turnng out.Back foot not on toe yet.Front heel is now down with firm flexed front knee ready to proceed with balanced leg contribution to continued rotation around a stable axis.I suspect this will be a fine swing.

tom.,

those "posed" stills at hitting.com don't deserve a comment. maybe a grunt - "ugh!".
