Was talking with a friend about something that Yoda mentioned
to me. If you stand too upright without waist bend and knee flex
then the hips cannot rotate correctly. You have no Hula Hula.
My friend said that he could related to that. When he taught his
kids to use a Hula Hoop, he demomstrated that standing straight
up the Hula Hoop would not revolve very good. When bent over,
he could really spin the thing. Nice example.
I have a question, in order to do the hula hula exercise, or to drive the right shoulder on plane through the ball efficiently using hip's power, does the hips have to "face", be vertical (or close to vertical the better) to the swing plane, ideally the rotated shoulder turn address angle ?
Hula Hula is really the ability for the hips to rotate without moving the head or the shoulders and it is caused by the bending (flexing / straightening) of the knees. It isn't a lateral move of the hips.
Stand straight, facing a wall with shoulders, hips, knees and foot line parallel to the wall. Slightly flex the knees and bend forward as in a golf posture. Make sure your hips and shoulders are parallel to the wall.
Bend the left knee so that it goes about 4-5" out while simultaneously straightening your right knee so that it goes about the same distance in, as per standard knee action. Just a bending and straigtening of the knees.
Neither your head nor your shoulders should have moved; but your hips are now turned anywhere from 25 to 45 degrees, depending on your flexibility.
That's Hula-Hula!
Per 7-14: The Hip Turn as a Stroke Component is strictly the product of the Knee Bend and the Waist Bend.
I think the Pivot, regarding hip motion and Hip Action has not been given enough pages in the yellow book. Hip motion is simple to understand but Hip Action requires specific setup, muscles and propulsion. Those attributes are not addressed.
