In a recent thread post I talked about Jim McClean's [golf instructor] concept of the "hip rise."

Here's a good slo-mo clip of Prince Fielder showing this [further slow it down via the .25 settings]:

Note the hip line change from relatively horizontal to the ground to much more DIAGAONAL to the ground from lead heel up to foot plant.

Also note---and this is very important---that though the lead shoulder "dips" [due to lead side lateral flexion] at heel up, by foot plant the shoulder line is more symmetrical [the "dip" is not there so to speak].

From a biomechanical perspective, this makes perfect sense in that in order to optimize momentum, rotational force needs to happen around the transverse plane of the shoulder line.

That, as opposed to creating lateral flexion ["dipping" then "un-dipping ", so to speak,] i.e., anterior-posterior axis to initiate the unloading. Quite a few seem to think the "dipping" [lead side lateral flexion] somehow potentiates the unload.

Untrue and incorrect from a biomechanical perspective. Unloading --via a "ferris wheel" type motion, as opposed to the MUCH more correct "merry-go -round" angular motion, is a less than optimal unloading.[ This goes to the issue of DIRECTION of force/momentum].

I would only add that, as I have said MANY times, I don't make up the biomechancal "rules" that best explain movement! But, simply put:

In the context of throwing and swinging, I just know these rules really well!!
