Hinge action is what? Controlling the clubface through the impact interval - which takes what - 1/1000th of a second???
And swivel is the rotation of the hands into and out of the impact interval.
But the true way to practice is to practice the motions relative to the associated plane, no? Just seems like...while I understand and appreciate the concept of hinge action itself...it is inherent in the motion taken relative to the associated plane - vertical, angled, horizontal.
