I know you probably expected a post about the Presidents Cup but we've got plenty of time for that this week. Instead, I want to look in more detail at something Michael Breed discussed on Monday's Golf Fix. (I looked for a video clip at the GC website but it's not up yet.)
Breed called that something TRAIL ARM ARC but many players and teachers refer to it differently. Annika Sorenstam, for example, has talked about how she tried to feel as if she was pushing her trailing hand away from her shoulder when she reached the top of her backswing. Breed's 'trail arm arc' is the same thing.
The reason I determined to put in writing approximately it's far because this 'move' allows you create extra clubhead velocity, despite the fact that the good judgment behind it may no longer be with ease obvious to you. But the concept itself is truly easy to understand.
To help give an explanation for this I'm using every other of my stick determine drawings. The motive I use stick figures and not photos is due to the fact ten people may be in the specific same position and all will look specific. However, stick figures constantly show the equal angles, and people angles are what you want to recognize. So here's the drawing:

Let's focus on the top figures first.
- The thick dark lines represent your shoulders and the thin black vertical line represents your spine. The letter 'b' represents the angle your shoulders turn.
- The straight blue line represents your lead arm, which is straight of course, and the small black circle represents your hands.
- The bent black line represents your trailing arm, which is bent at the elbow. The angle of that bend is labeled 'a'.
- And the thin green line extending across the drawing represents where your hands are at the top of your backswing. The club shaft would be pointing down this line, over your shoulders and toward your target.
Are you with me to this point?
Now, you may have heard that the 'textbook' amount of bend in your trailing elbow (it is 'a' inside the drawings) is around ninety tiers. And in case you examine my drawings, you'll see that the LONG arc is only a little over 90 stages. That's because it's really difficult to push your hands very a long way faraway from your trailing shoulder at the top of your swing.
You must be asking yourself, "Why?" The answer to this question is why pushing your trailing hand away from your trailing shoulder creates more clubhead pace.
When you push your trailing hand away from your trailing shoulder, you pressure your self to make a larger shoulder flip -- or 'coil' in case you pick that phrase.
Look at the distinction in 'b' among the ones two drawings. The SHORT arc receives the arms to the top of your backswing with out out growing very much shoulder coil at all! However, the LONG arc creates a much bigger shoulder coil, which lengthens your swing and gives you more time to build pace throughout your downswing.
And in case you examine the bottom drawing within the the grey container, you may see a drawing with the SHORT arc's shoulder turn but the LONG arc's hand position. See how the hands are nowhere close to the pinnacle of the backswing? That's because the swing is so much shorter, and that is why it doesn't create as an awful lot swing pace.
So let me sum this up: The reason you want a LONG Trailing Arm Arc is because it forces you to make a bigger shoulder turn, and a bigger shoulder turn helps you create more swing speed.
I hope that helps you understand why Breed made such a big deal out of this, and why so many players and teachers talk about pushing your hands away from your trailing shoulder at the top of your backswing. It's all about creating a big shoulder coil.
