Part 7A will just go over the First Power Accumulator (6-B-1-0) and Extensor Action (6-B-1-D). Understanding the Power Accumulators and the Pressure Points are things that I've seen greatly help golfers even if they don't understand the rest of TGM. Each Power Accumulator discussed in the book talks briefly about the actual power accumulator and then talks about getting maximum power from the power accumulator. Then conversely it talks about what would provide zero power, then it discusses 'maximum trigger delay' from that accumulator.
6-B-1-0 (The First Power Accumulator)
This is the folding and then straightening of the right arm. The #1 Power Accumulator 'loads' as it folds in the backswing. It then starts to unload all that power as it steadily straightens in the downsing. Take a look at Hogan's swing and see how the right arm folds and then straighten and becomes fully extended in the follow through.
Again, notice how Hogan's right arm is bent as the club is almost at impact. Hackers tend to have a straight right arm at impact.
This folding and straightening of the right arm is very much akin to a boxer throwing a punch.
The right arm can only straighten as the left arm moves away from the right shoulder. Homer talks about the 'paddlewheel' and the paddlewheel motion. Below is a diagram of a paddlewheel.
These are used on ferries and steamboats to propel the boat forward. So imagine your right arm as one of the 'spokes' in the paddlewheel and the right arm pushes down in a counterclockwise motion, just like a paddlewheel.
The swinger does not use the #1 power accumulator according to TGM. Today's physicists are saying that's not exactly true, but according to TGM, the swinger does not use the right arm.
Maximum force is produced by developing faster hand speed. But remember, according to the Endless Belt Effect, the hand speed must stay constant in the downswing.
Only possible when the golfer pulls solely with the left arm. This is used by the swinger. The hitter *can* pull with the left arm slightly. I will get into this later on.
Maximum Trigger Delay
Delaying the lag of the club can be done by maintaining the wristcock on the downswing until the right elbow, from the golfer's perspective, 'passes the ball.' This may not be easily accomplished. However, I would suggest for those who want to have the right elbow 'pass the ball', they should greatly slow down their hand speed according to the Endless Belt Effect. This move of getting the right elbow to 'pass the ball' is part of pitch elbow, which I will get into later.
6-B-1-D (Extensor Action)
The base definition of Extensor Action is in the first line. It's exclusively the steady effort to straighten the bent right arm.
Homer also states:
It is in operation from Impact Fix to the end of the follow through.Remember, at impact fix you're trying to get 'impact hands' at address. However, you're also trying to get 'impact elbow' at address. Since the right elbow is bent at impact, if you utilize 'impact hands' at address, then you want a bent right elbow.
Remember, extensor action is the steady effort to straighten the bent right arm. So it's not just a case of the right arm straightening out from the top of the swing to the follow thru. But it's actually the right arm straightening from the first place it's bent --- impact fix (provided the golfer uses impact hands at address).
Extensor Action also promotes:
1. Full extension of the left arm at all times
2. Full extension of the right arm for the follow through
3. The correct rate of clubhead closing
4. The proper type of support for 'passive' Clubhead Lag Pressure involving Wristcock.
Basically what extensor action does is it keeps your left arm straight on the downswing thru proper use of your right arm.
Furthermore, the right arm has a 'natural' need to fold at the elbow. So at impact fix, the right elbow is slightly bent. From impact fix to the top of the swing the right arm goes from bent to folding at the elbow. Then from the top of the swing to the follow thru, the right arm goes from folded at the elbow to straightening out into extension.
Because the right arm has a 'natural need' to *fold* at the elbow, proper extensor action will prevent this from happening and also prevent the left arm from bending. Here's a great pic of proper extensor action and improper extensor action and the problems it creates.
