[Yoda]

There's this piece of equipment at my gym that replicates a standing shoulder fly.

I liken a golf swing w/o extensor action to someone who attempts to do a dumbbell shoulder fly with too much weight for them. Their head moves, their elbow bends, and their knees sag, all to compensate for the weight that they cannot control with their hand and triceps muscle only. On the other hand, proper extensor action ensures that the head will remain steady, the right elbow bend is constant, and the shoulder/hip/knee slant all respond to the path of the hands.

If you know the type of machine I'm talking about, or can imagine it, that's just my way of feeling extensor action, coupled with a startup swivel. I know it took a while, it's just one of those things that's harder to explain in words, but able to demonstrate in a few seconds.

Thanks for reading my novel approach to extensor action...pun intended

Welcome aboard, laangels, and thanks for this first post.

Each of us brings our own unique experiences to their study of The Golfing Machine. I am for whatever helps one understand and produce the required alignments during their golf stroke.

So . . .

Let'er 'fly'.

Pun intended!
