Assume the position you would be in when rotation starts and simply start your swing (rotate) from that point, with no forward movement of your Center of Gravity. Apply THT or BHT, work your front shoulder all the way back to the catcher while your top hand assumes the “L”,but simply do not allow your Center of Gravity (your belly button is approximate enough) to move forward.

ray..."Assume the position you would be in when rotation starts and simply start your swing (rotate) from that point, with no forward movement of your Center of Gravity.".....

as chrley lau said, you have to go back before you can go forward...whether a stride is simply overcoming inertia or whether it is something else in addition to overcomimg inertia, the situation you described is simply starting a swing from a dead stop...so adding the stride/load/go back first, whatever you want to call it, it is needed to overcome inertia...but does that mean it is "weight shift"?...if not, than the question still remains, what is weight shift?....if so (if it IS weight shift), then what IS weight shift over and beyond simply an inertia-busting mechanic?

what i would like to know is how/why some coaches equate x amount of weight shift with y amount of power...
