>>> My first question is that although each leg must push with equal force on the pelvic structure to cause rotation, do both have to be pushed in unison, or can you push the back leg open 45 degrees with back leg first, then use the front leg to open the front part of the hip structure second?
The second pertains to your quick thoughts on how to use the bag correctly. Should I hear loud thud! and knock it off its post. In other words, what are some aural and kinesthetic cues to ensure I am performing the drill correctly. <<<

Hi BHL

I think we have discussed this before. -- I understand that both legs are probably contributing fairly equal to rotation. But to honest, in my swing, it feels to me that I am using the lead leg to cause most of the hip rotation. I can feel the back knee turning as I pivot, but it seems more automatic rather than something I intentionally do.

Some coaches that I have a lot of respect for would say that the hips should open (30+ degrees) before the torso muscles are contracted to start shoulder rotation. I still cannot find a sound reason to support this theory. Although a few of the better hitters do open their hips before shoulder rotation is initiated, I think it may be more of a holdover from their linear mechanics days. -- With linear mechanics the batter turns and extends the back arm similar to a boxer delivering a punch to an opponent’s mid-section. When delivering this type of arm action, striding with the toe open and having the hips open before shoulder rotation feels more powerful. -- In order to slow this early opening of the hips, many coaches would have their player’s stride with the front toe closed.

BHL, would you mind resubmitting your second question later. It will require some time to answer it.
